  1. Sorry for being really, really late. Uni has been taking time... Just the other day, I accidentally broke Optimus and the eGPU only worked only on an external monitor. Confused about why it was doing so, I thought of an SMC and PRAM reset. Link to SMC reset: https://support.apple.com/en-us/HT201295 Link to PRAM reset: http://guides.macrumors.com/Zapping_The_PRAM Everything went back to normal after those were reset; Optimus worked again on Windows 10 for me. Maybe try those?
  2. Hmm, that is really weird. I have upgraded to 362.00 as well and it hasn't affected Optimus for me. Did you clean install the drivers or were they "express installed?" If you didn't clean install the drivers, perhaps you should try it. However, it probably isn't a good idea to try the 364.47 driver yet as it is known to cause various problems. More on that here I hope that helps somehow. Anyone else have any ideas?
  3. @Dschijn No, the internal display for me isn't limited to 60fps. Tested Heaven at very low settings As you can see, it is at 92 fps here. But, the results were a lot lower than I anticipated for such a reduction in quality from extreme (only rose maybe 1000 points at the most). @DschijnMaybe vsync is on somewhere?
  4. I know you already reverted back to Windows 8.1 but for everyone else out there. Try out different boot procedures! Every setup is unique and there is no one-size-fits-all for boot procedures. Sometimes, even though the EGPU is seen, it wasn't actually initialized correctly, leading to it not actually working; yes, it does take a bit of fiddling around to get it to work properly. But in my case, I found that Windows 10 works perfectly fine for Optimus for me with a mid-2014 15" MBP with Iris only. I use a Gigabyte miniITX 970
  5. Anyways, time for me to upload my proof. Using this Boot procedure: I decided to run firestrike from the 3dMark demo on steam with only the internal display on (no external monitors plugged in) to show everyone optimus works in Windows 10 (at least for the mid 2014 15in MBP Iris Only...still need confirmation for other systems) Note the display size and the operating system. 2880 x 1800 is obviously the internal display for 15" Macbook Pros since 2012. But, Geforce experience doesn't show you the performance. Here is my 3Dmark Result with the internal display: http://www.3dmark.com/3dm/10694991? Compare this with the 3DMark Result on an external display with the same clock speeds: http://www.3dmark.com/fs/7439086 These results are totally consistent with the performance loss (-14% performance) due to Optimus. It is also quite obvious that the egpu is working with a score of ~7700 in firestrike. Hence, please continue to ask me questions and don't give up on Windows 10 so easily! I will try my best to answer ones I know about. @Dschijn can answer the rest -ZapCord
  6. Interesting that a lot of people aren't able to get Optimus working in Windows 10. I am honestly surprised. Another boot procedure that works (for me): -external displays aren't plugged in to start connect thunderbolt cable from egpu to laptop boot laptop while holding alt to get to boot select screen Start EGPU wait 30 seconds Select Windows Once Login screen is reached, plug monitors in if external displays are needed Otherwise, just log in I hope this helps someone. EDIT: And no, I did not use Evo's guide to enable optimus
  7. @stemoac interesting, maybe try booting up with only the egpu and internal monitor connected at first (same procedure) and then connect the external monitor to the gpu after boot. You'll get a few screen flickers right after boot but it is ok. Are you sure you are using driver version 361.75? My setup during the test was: GTX 970 with 361.75 (none of this worked pre 361.75 and the computer was using integrated only on internal display) 2 1920x1080 external monitors connected by DVI Internal display was primary display. -All of these were on extended display mode.
  8. @stemoac Greetings! It is very much possible to run both displays with nvidia. However, the internal display will not show the egpu as its display adapter. -That is due to the fact that the internal display is connected to the integrated graphics no matter what; however, the brunt-work is still handled by the egpu. You can see this in the spoiler below. -Notice that the score is a little bit less than the one I posted above in my original post as it is run on the internal monitor. -That is due to the inefficiency of having to route all traffic through the integrated graphics no matter what for the internal display. I hope this clears it up! EDIT: grammar errors
  9. Can confirm Optimus now works on my mid-2014 Macbook Pro 15 with Iris only graphics using driver version 361.75 I am not too sure on that. Someone should try with the latest drivers on a dgpu model.
  10. CAN CONFIRM OPTIMUS NOW WORKS!!! Tested on Warframe and the game looks nice on the internal screen (yay). To get Optimus working on Windows 10, install driver version 361.75 released 1/27/2016 Boot procedure is now: plug everything in start egpu start laptop wait 30 seconds boot Profit Big Thanks to Everyone!
  11. First of all, big thanks to Dschijn, nando, goalque and the rest for their fantastic guides! EDIT:MUCH THANKS TO @goalque FOR THE SCRIPT TO GET THIS WORKING ON OSX!! Tested Computer: 2014 15" MBP with Iris Pro only; i7-4770hq @ 2.2 GHz (Turbo to 3.4); 500 gb ssd Parts List: PSU: EVGA 600 B1 80+ BRONZE GPU: Gigabyte GeForce GTX 970 Mini ITX Overclocked GV-N970IXOC-4GD Thunderbolt 2 Enclosure: AKiTiO Thunder2 PCIE box Cables: 2 Molex to 1 PCIE cable (to make a molex to barrel adapter) 2.5mm x 5.5 mm male DC Barrel Plug (screw terminals are the easiest) Monitor: Dell 1920x1080 ^^Not sure why there are links there... Procedure: 1) Install Windows 10 via bootcamp instructions here 2) Download latest Nvidia drivers here 3) Open Akitio enclosure 4) Line up the x16 on the graphics card with the physical x16 slot on the Akitio. Push in the graphics card and screw the top screws on the Akitio to hold the graphics card steady. Plug in the PCIe 6/8 pin connector(s) from the PSU into the graphics card. 5) Make a Molex to Barrel Adapter using the 2 molex to 1 PCIE cable in conjunction with the barrel plug instructions here As Dschijn suggested, I made the barrel plug with 2x molex instead of 1x molex by twisting together 1 yellow wire (12V) from each molex connector and 1 ground from each molex. The yellows go in the positive terminal while the grounds go in the negative; make sure the plug is center positive! Be sure to check polarity of the barrel plug with a multi meter to make sure it is center positive! 6) Plug in the molex to barrel adapter into the PSU's molex connectors. Apply the paperclip trick or adapter on the PSU's 20/24 pin connector 7) Plug the barrel into the Akitio's power input 8) Connect the thunderbolt cable from the Akitio into the Macbook 9) Connect the video output cable from the eGPU to your desired monitor 10) Turn on the Mac while holding "Alt" 11) When the boot selection screen appears, turn on the PSU (I use a power strip) 12) Count to 5/wait for the fans on the GPU to spin up 13) Select "Windows" on the boot screen 14) Install Nvidia drivers 15) Follow the prompts to restart the computer and what not. 16) Profit The Boot Procedure that works most of the time for me: Assuming everything is plugged in, power on the macbook while holding Alt When boot selection appears, turn on the PSU with a power strip Count to 5 or wait for GPU fans to spin up Select Windows Both screens should work. If not, turn everything off and try again. I use Intel's XTU tool to undervolt and underclock its boost speed to reduce heat output. I underclocked it to 3.0 GHz and undervolted it by -75 mV. There are UV guides on the internet I used EVGA's Precision tool to OC the Graphics card. I managed to get +190 MHz on the core clock and +350 MHz (+700 MHz effective) on the memory (probably could push further). I also use a custom fan curve on the GPU via EVGA's Precision Tool. Temps never go above 61 degrees Celsius. Games: World of Tanks runs everything on Max/High 60fps @ 1080p with VSync and Triple Buffering on Witcher 3 runs Max/High no hairworks smoothly with no noticeable drops Naval Action (In alpha) runs everything on max no AA (kills fps in this game at this moment) @ 1080p open world and combat CSGO obviously no problems BF4 high in multiplayer @ 1080p and 60 fps Warframe is smooth everywhere on Max including Physx @ 1080p and 60fps Fallout 4 is same as above as far as I could tell Questions are welcome even though I might not be able to answer all of them. EDIT: Almost forgot to mention the paperclip trick Images: http://imgur.com/a/I9jaf External 1920x1080 Monitor: Heaven 4.0: Extreme settings at 1920x1080 with extreme Tess. and 8x AA GPU OC: +190/+350 Score: 1310 Valley: Extreme HD settings 1920x1080 GPU OC: +190/+200 score: 2318 Firestrike: +150/+200 Score: 8980 +190/+200 Score: 9154 SteamVR Performance Test: VR Ready +150/+200 Fidelity could be higher with a higher overclock CPU: limited to 3.0 Ghz and undervolted by 75 mV via Intel XTU Note: It says Iris Pro Graphics for GPU but it actually tested the GTX 970 Fidelity: High 6.2 Frames below 90 fps: 0 Frames CPU Bound: 0 Windows 10 Optimus Heaven: same settings as above, +150/+200 Score: 1137 ~13% performance loss Firestrike (demo version on steam): +150/+200 Score: 7754 ~14% performance loss
