I'm aware, but no idea what causes it.
It also doesn't really help that legal versions of this game do not work with wine, which doesn't exactly make debugging this any easier.
Seems somewhat on the extreme side, but if I look at some windows complaints seems like a drop of >= 4x is to be expected on AMD GCN3 hardware. On the radv side I guess we could put an option in to limit the max tessellation factors just like the windows drivers have.
Found the reason, it was due to the fact that the folder with the game was available only for reading.
Secondly, it turned out that the dxvk.conf file must be inside the prefix.
Third, the cache folder must also be in the prefix.
After fixing all the problems, the game began to work quickly.
Nothing extracted yet.

My game directory default is read only mode, except d3d11.log and dxgi.log files.
Does DXVK write anything to the game catalog?
