When I boot my pc (Windows 10) after it is off/in sleep mode the performance of my GPU is way worse than it is should be. Only after rebooting it (OS reboot, not shut down and start with power button) usually the performance is as expected but sometimes it takes two or three reboots before it works well. It has been this way for quite a while, even after multiple driver wipes (with DDU) and updates.
- GTX 770 MSI gaming version
- i5 4670K overclocked a bit
- Mobo: Gigabyte GA Z97X Gaming 3
- PSU: Corsair CS650M
Heaven scores (1080p high 4xAA normal tesselation)
when performing well:
1418 (56 fps)
when performing poorly:
683 (27 fps and very choppy/stuttery)
The weird thing is that the GPU/CPU usage/temps/(v)ram usage/GPU boost clock etc. seem to be pretty much exactly the same in both states. Does anyone have any idea what could be causing this?
