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.
