Almost certainly a sync bug from some recent reworks, I'll look into it.
Just need to pray it actually reproduces with the demo.
Turns out it wasn't a synchronization issue, it was a shader issue instead.
Still not 100% sure if the fix is correct and if there's perhaps driver memes happening, but it works on my 4070 now.
Nothing extracted yet.
Using latest Git version of DXVK, ME:Shadow of War shows graphical issues, parts of the vegetation (grass,bushes,trees) flicker in and out of view randomly. The game works fine with DXVK 2.7.1, seems to be a regression.
Also already affects newer versions of Proton since they use DXVK git.
A git bisect pointed to the new DXBC shader compiler introduced last year being the problem.
