Hi!

I’m experiencing some clocking issues with driver 570.86.16, RTX 5080 and some games, especially Hogwarts Legacy. Somehow the GPU won’t clock above 780 MHz, so performance is very bad. See the attached screenshot showing mangohud.
This only happens when Nvidia Reflex Low Latency is enabled (i.e. frame generation).
The funny thing is, that it will usually just run fine when I disable it ingame (GPU will immediately throttle back up to full power) and then reenable it again (GPU will stay at full power)
I don't really know if this is driver related or vkd3d related. There seem to be no obvious errors...

This smells like a major driver bug, we have no way to control GPU clocks in any way whatsoever.

Nvidia has confirmed and reproduced this issues and it appears to be a driver bug, so not related to proton.

Nothing extracted yet.
