Only 48fps with Gtx 970 on Internal Screen, help!

Recommended Posts

Hi everyone, I've made this post to gather as much information of the problem I'm facing with my Gtx 970 egpu setup, so if anyone is suffering something similar it would be really helpful if you could share your setup too.

My Lenovo y510p Setup:

Cpu: intel i7-4700MQ

8gb of ram

Windows 8.1

Bplus PE4C v3.0 adapter mPCIe

Gpu: MSI Gtx 970 (4gd5 oc)

Evga 500 power supply

 

My setup is working find without errors but whats bothering me is that when I'm using Internal Screen to play my fps won't go beyond 48-49fps no matter how old the game is DX9, DX10-11.

I've tried to lower graphic settings, resolution, disable full-screen on all the games and but still stuck at 48fps. I know I should get lower performance because of internal screen but fps shouldn't be limited to 48?

What I've tried but non helped :

Installing different drivers.

Overcloking gpu.

Changing nvidia global settings, like vsync, etc..

 

 

Share Your experience if you have similar behavior on your egpu.

 

Edit. Found Someone http://www.owen-lu.com/egpu/ with same behavior with gtx970 but using ExpressCard connection.

Is that value close to the refresh rate of your display? Like 49-50Hz?

My laptop screen has a 60hz refresh rate, and vsync won't help at all.

PD. I think it has to be something with my gpu, gtx 970.

Ok, I asked because I was limited to 60fps when using the internal display of my MacBook in the past.

Are you saying that you're using an Optimus setup that only has the internal screen, and that it's limited to 48FPS,

or are you saying that you have an external screen, but are rendering to the internal screen while capped to 48FPS?

Yeah optimus but not reaching more than 48fps

1. is it limited on an external monitor?

2. have a game running in the background on the internal screen and then load up GPU-Z. Go to the sensors tab and look at the performance cap graph. Does that show any thing bottlenecking the performance?

1. No, it's unlimited. Just on internal has the limit.

      Hi,
      I want to show you my new project.
      I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.
       
      Its specification:
      Intel i7-4700MQ
      Nvidia GeForce GT745M
      16GB RAM
      512 SSD Adata SU800

       
      Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
       
      So I make a decision to buy external grahpic card.
      I choose GTX970 and now I am looking for occasion to buy it.
       
      I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

       
      I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
       
      My plan:
      1) unlock bios
      2) buy GTX 970
      3) enjoy Witcher 3!
       
      BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
       
      1) laptop on table, playing GTA V 1080p

       
      - first minute (GPU core 1045MHz)

       
      -after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

       
      2) with thermalpad Glacier NC400 SilentiumPC

      - 30 minute and longer (GPU core drop to about 900MHz)
       
      3) without down case of laptop (like on picture with thermal paste) on thermalpad.
      Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

       
       
      Bacause of that I bought second down case for my laptop and I will cut there additional holes.
       
      Greetings!
       
      I will describe next step when I get all stuff I need!

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.

      Hello!
       
      I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
       
      thanks.

      Hi there guys,
       
      I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
       
      I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
       

       
      The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
       
      If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
       
      Thanks.
