Mod is pretty good, having no problems what so ever with it, when using 30fps, I can easly run game at 3x, while when using 60fps I run it without problem 2x res scale...
My PC:
R7 5800X3D
2x16GB DDR4 3.2GHz
RX 6700XT
M.2 SSD
3440x1440 < wish we had 21:9 mod as there was for CemU :)
One problem though, as of now, with 60fps mod, shrines are like 2x speed up...
