The same for me, AMD Fidelity FX Mod works better than DLSS from Assetto CC.
I hope I can go back to my previous settings.
It’s time to start looking for the folder in which to replace it.
Having tried it with OpenFSR, I’d say upscaling could be perceived to work especially well with Skyrim, thanks to the “aquarel”-y effect it tends to produce synergising quite well with the “wax crayon”-y artstyle that Elder Scrolls games have… :7
In other Skyrim news: Prolific Skyrim VR player Cangar has made a mod that maps your mana level to your relaxation level, as read from a consumer grade EEG headband. 
So much exciting stuff happening with VR mods atm. Go Cangar, really happy for him. How freaking cool is his mod idea.
So I tested with the new 1.8 ACC update , 3090 and a 8700K on windows 11
Disabled the hardware acceleration as mentioned above , but still had many stutters on my 8KX , did a fresh install with DDU of the latest Nvidia driver and am able to run ACC on VR Epic preset with a couple small adaptations (140->110 resolution scale) and having Smart Smoothing enabled , now I am getting a stable 45fps ~> 90fps with less then 20ms in FPSVR , smooth gameplay , so DLSS is a game changer !
DLSS in ACC on Perfomance with 30% sharpening seems to work quite well ,
Please let me know if you would have any suggestions for improvements!
