Whenever playing ACU with DXVK, the lights or shadows will start flickering like crazy, you just need to add dxvk and play the game to reproduce

Works fine on Linux as usual. Kinda getting tired of these problems with AMD's Windows driver that don't really reproduce anywhere else, impossible to tell whether any of these are genuine bugs on our end or just driver memes.

@VanitasFR I have a similar issue with AC Origins here #5356 , can't say if it's shadows tho. You might try with DXVK v2.5.3 or downgrade Radeon drivers to v25.9.1 and see if it's related.

DXVK 2.5.3 works as intended like @vturcotte mentionned, using Adrenalin 25.11.1
