[PC] Sudden CPU rendering

Alright so i am the victim of one of the crashes in 5-30 minutes bug… I still try to play it even though i know it’s gonna crash (i think it’s THAT good, if only the staf would show that support to us, but i digress)… Out of no where, I crash today, restart the game again and now i am forced to use a “console mode” .
Basically, my GPU does not get utelized and locks at about 34% utelization. I get about 30-35 FPS ingame, while yesterday i got about 110-150…
Tried upgrading my drivers to 416.6 (didn’t help), downgraded again to 411.7 (didn’t help), reinstalling the game (didn’t help), terminated and resetted the game (didn’t help) and also tried to run the game with as least programms open as possible…
Now the strangest thing is, in the main menu, i DO get my 165 FPS, but that’s mainly because my GPU doesn’t get stressed past 34% utelization. I have a 1080 Ti so Vram isn’t an issue, also other games are not an issue.

Update: Forza uses CPU Rendering instead of my GPU, while it actually knows the GPU is there and ready…

Alright fixed it somehow (i can’t imagine i haven’t done this before), by editing: NVIDIA Control Panel → Manage 3D Settings → Global Settings → Set Power management mode to Prefer maximum performance… Now my FPS are back: Good benchmark da - Album on Imgur
