We have some unofficial drivers (beta). We will check them. DX12 should work flawless
The drop is huge and unacceptable.
Can you post the exact driver number (462.xx) the shows this problem?
BTW1. Any chance to test with VSYNC enabled? Or are you running 120Hz display?
BTW2. We will check Dirt 5 on RTX 2080 tomorrow (with newest drivers)
Thanks for following up on this!
I was going to do a nice big write up but I think
I've found the cause - Hardware accelerated GPU Scheduling (HAGS).
I reinstalled the Nvidia driver fresh again - 460.71 - and it was smooth and had no issues. I rebooted and the issues came back, which prompted me to think about HAGS. Turned it off, rebooted and now I'm not getting the performance issues when using timeshift...
BOCW, Dirt and Division all have 1-3fps drops when timeshift is on which is what I expect. Everything is smooth now...
Just in case - I'm using freesync (well, GSync compatible) with forced VSync, plus low latency on and 142fps cap. 144hz monitor.
I'm not sure why this hasn't affected me before or why it's fine on 457.xx drivers. I might be jumping to conclusions but I can't replicate my issue with HAGS off... I'll see if it still behaves tomorrow.
