Gaming Performances & Behaviours

Recommended Posts

Im trying to start a thread where we can organise comments specifically about gaming performances with our EGPU rather than have all that scattered around the forum

Comparing to to my desktop PC build (I5, 8go ram and gtx970) the EGPU system is definitely slower on Elite dangerous and also on other games that I can't include right now because I have not played them on this build so far. Two main comments:

- FPS is around 30-45 FPS in Elite Dangerous (almost max settings) but many times dropping around 20 so It can be a drag sometime because I had full 60 FPS on the PC build; that is quite a loss but still playable. Curiously, lowering graphic settings do not give much gain (about 10FPS more)

The MAC version of the game is still recent so I expect some software tweaks but still wondering where does the problem comes from. Maybe a TB1 bottle neck? Looking at ISTATS I can see that the GTX gets used at 70%max of its capacity; is this normal ? Could someone with OS X and GTX970 comment on that ?

- Macbook FAN Behaviour: looking at Istats, my CPU appears o be used at about 10-20% so not much but still showing above 80 degrees so the fans are kicking quite a lot (5000RPM). Any comment on that would be much appreciated too. I have ordered a laptop cooler to see I that helps.

- Another FAN issue while this one inaudible is the GTX 970 that appears to have one of its fan only running after gaming sessions. Reboot fixes the problem and the fans are off when not playing. Anyone having this issue?

I Scored 1213 on Heaven Benchmark on extreme settings, is this a normal score ?

My build is :

Thunderbolt 1

Webdrivers: 346.01.02f03

EVGA GTX 970 4go

Mid 2012 Macbook pro retina I7 2.6 Ghz

Akitio + GTX 970

OSX 10.10.3

I would suggest when doing your desktop vs eGPU comparison you do so on the same OS platform. OSX gaming isn't as optimized as Windows gaming.

Pls install Windows 7 or 8.1 on your Macbook, load your game and then compare to your desktop system.

Im easy on that. I can see the benefits of both in the same thread too but feel free to add it to the title if you think thats better.

On windows on my mac, sorry but that's not going to happen, I'm allergic to windows (even if I must admit win 10 is looking good) and will not install it on my macbook :61:

Fair enough. Though can you confirm you are comparing Windows gaming performance on your desktop to OSX gaming on your Macbook? Just want to make sure you haven't Hackintoshed your desktop PC or are using a MacPro or whatno.

Yes Im comparing to my desktop PC (that I want to sell so bad, Im itching every minutes). No hackintosh here.

I made some PC vs. eGPU Benchmarks in my first guide: http://forum.techinferno.com/implementation-guides-apple/7879-2013-13-macbook-pro-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-osx10-10-%5Bdschijn.html

For gaming I strongly recommend to use Windows 8.1! Gaming performance is just amazing and OSX still doesn't have well made GPU driver for high end performance.

Your problems could be a bad Mac version of the game, TB1 and not good driver.

As soon as some load is on the Mac for a continuous period of time, the temperatures will rise. The fan profile is adjusted to provide very quiet operation for a wide temperature range, but if you get above e.g. 70°C the fans will start spinning up pretty fast. For best CPU performance you can set the fans to 100% fix, because you without that the fan can't spin up and cool the CPU as fast as the CPUs temperature will rise. By that the temperature will win the race and the CPU has to clock down.

In windows you can also make adjustments to the CPUs vcore by reducing the voltage and by that increase long time performance of the CPU.

Is the GPUs temperature getting below 60°C when one fan doesn't stop? Maybe a driver is interfering the GPUs fan profile.

I would agree on that

I see on your graph that you lost about 20% performance on your windows EGPU comparatively to your desktop build. I would estimate my loss between 30% and 40% but I would need to put my card back into the desktop to benchmark first. OS X is definitely less optimised.

Would be useful to get many heaven benchmarks from different OS X configs to get a base for comparing. Comparing in one game is not very accurate too.

My biggest question right now is why I don't get a 100% load on the eGPU

As soon as some load is on the Mac for a continuous period of time, the temperatures will rise. The fan profile is adjusted to provide very quiet operation for a wide temperature range, but if you get above e.g. 70°C the fans will start spinning up pretty fast. For best CPU performance you can set the fans to 100% fix, because you without that the fan can't spin up and cool the CPU as fast as the CPUs temperature will rise. By that the temperature will win the race and the CPU has to clock down.

In windows you can also make adjustments to the CPUs vcore by reducing the voltage and by that increase long time performance of the CPU.

Setting the Fans 100% ON is counter productive for me as I am trying to get less noise.

Yes I wish I could down clock too, I7 is actually way too much for gaming lol. Istats show about 20% of use during gaming. That's also the reason why I don't get why it heats up so much with 20%..

Is the GPUs temperature getting below 60°C when one fan doesn't stop? Maybe a driver is interfering the GPUs fan profile.

Yes, internal 650 shows 43ºc, EGPU has fans off before I start the game so yes too.

CPU idle is 48ºc

I'm running my CPU without turbo. That keeps the CPU at around 60°C at most and it keeps the fans quiet so I can't hear them. I'm using Macs Fan Control with both fans controlled by CPU temperature. They're set to start rising their rpm at 50°C and max. that shall be reached is set to 75°C. This, together with the "disabled" turbo, keeps the book more or less unhearable but I don't have any issues regarding performance for now. Once there are issues I can still enable the turbo again.

This is on Windows, though. Macs Fan Control is available on OS X, too. You may have a look if there's a way to disable the turbo on OS X as well. This should lead to the same behaviour.

Apart from this I've been playing most recent games without problems. If there's a thing that's limiting then it is my GTX 960.

Thanks a million for that ! I did not think of turbo boost :D

After putting it in google it seems that this would solve my fan issues like they say here

HAHA there is an APP for disabling turbo boost !!!!! SILENCE IS MINE :Banane14:

Turbo Boost Switcher for OS X | rugarciap.com

Enjoy ! Testing now

Edit: It improved greatly: 1000rpm less (around 3500rpm now) so fan noise is bearable now. CPU 81º. Now I can also adjust the fan speed manually with Istats so will continue to test this. Still 20% load on the cpu during gaming.

What RPM are your fans running at under full load?

What RPM are your fans running at under full load?

They go up to 100% under full load but that's what I want them to do. Full load = 100% CPU usage. Temperature shown by Macs Fan Control is ~80°C but the Intel Power Gadget shows up to 87°C. I don't know why they differ but it's the same on OS X.

If you want to know what my RPM are under usual gaming load then I've just tested The Witcher 3 for you: ~2700 RPM @ ~55°C. It's always rougly about 60°C with this RPM or some more(3100)(GTA 5, DayZ, Arma 3, CS GO etc.). Fans can't be heard.

I posted this elsewhere but I was rather shocked to find that the CPU in my 1.4 Ghz 2014 Mini ran at 10Watts and very cool temps whilst playing Far Cry 4 at 4K. It stayed at 2Ghz and never broke a sweat.

Meanwhile, the GTX980 or Titan-X would always be roaring like a lion, as well as fans on the PSU running it.

But then you realize, that is why eGPU is such a great thing and why it is important to get the word out. The CPU was only needed at a minimal level, the GPU is doing all of the heavy lifting.

@MVC @Morv looks like 2014 macs run cooler than my 2012 macbook. Looks like Im running 10-15° hotter in general (turbo boost disabled).

Booked an apple store appointment to check inside (and finally take care of my dead pixel)

@MVC: Yeah the 1.4GHz version is using very very little amount of power and by that can be cooled easily. That is the CPU originaly used in the MacBook Air and later build into the low end Mini and iMac. With a quiet GPU that setup should offer great silent gaming!

@w4vz: A 3 year old MB might have a dusty cooler and dried up thermal paste. Cleaning and applying new paste should help a lot!

Hi,

I built an eGPU system today with a GTX 680 initially and now a GTX 770 and I can comment that I noticed the GTX 770 handles resolutions above 1080p much better than the 680 does despite having 2gb less RAM.

Not sure why but it feels like some sort of bottleneck on the 680 causing really severe framerate drops at higher resolutions.

Starcraft II and Heroes of the Storm running very nicely in OSX with GTX 770 at 2560 x 1440. Haven't tried 4K yet.. I'm under no illusions that it will suck over thunderbolt :D

Cheers!

Yes. In Windows you need to go into the power options and adjust the profile for battery usage.

I changed the power plan to high performance but there's still a huge difference plugged and unplugged.

Does disabling turbo boots have any effect on gaming performance? Using an Alienware m14x r2 for casual gaming, specifically, GTA Online and looking to get the most out of my gt650m.

Hi Guys,

I have problem with playing "Euro Truck Simulator 2". In this game i am getting very low performance. I tried low graphic settings and high settings but there is not any difference between these settings. This game is not playable. Also i am playing more powerfull games like "Witcher 3" and "GTA 5" but i have not any problem in these game. Do you have any idea about it?

My system is;

  • Acer v3 571G
  • i7 3630qm processor
  • 8GB 1600 mhz ram
  • Galax GTX 960 EX OC
  • EXP GDC Beast
  • Dedicated Monitor

- - - Updated - - -

Also i have same problem in "Reign of Kings".

@kayacan93: Can you try to monitor CPU and GPU during gaming? You could use GPU-Z to show graphs how load, clock speed, temperatures,... behave.

Have you installed the latest GPU driver?

Yes, i have installed latest gpu driver. I use to play this game with GT 640M and there was not problem. It is so annoying, i cant play this game with egpu.

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
       
      Here's some common problems and some troubleshooting steps to correct them.
       
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
       
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
       
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
       
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
       
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
       
      eGPU does not get detected
       
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
       
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
       
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
       
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
       
      eGPU still not detected - set the PSU to be permanently on
       
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
       
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
       
      http://forum.techinferno.com/enclosures-adapters/8441-%5Bguide%5D-switching-atx-psu-using-paperclip-trick-swex.html
      http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html
       
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
       
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
       
      eGPU still not detected - faulty hardware?
       
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
       
      NVidia driver stops responding
       
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
       
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.
    • By TheLoser1124
      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?
