Considering that there are profiles for DX12-only titles like Gears 4/5, Forza 4, etc I would definitely assume that the driver still handles some low level functionality and that there are limitations of DX12 that requires work to be done by the driver.
Hello. I noticed that the Nvidia profile for Metro Exodus does not apply to the UWP variant. I saw this thread on Nvidia: https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/319872/driver-profile-for-metro-exodus-does-not-apply-for/ Anyone know what to do about this? The profile includes some much needed stability and performance improvements. I checked on nvidia inspector on my system and there was no listing of the UWP executable on that profile, like the thread.
