Hi,

sadly i don't own the Witcher 3, but i have very similar performance issues in
all DX11 games in wine (Crysis2, Crysis3, Prey 2017 demo)

GPU: NVidia GTX970 (384.90 driver)
CPU: Core i5 3570K
RAM: 16GB

The CPU load is very high, but:

In all the games the GPU load is roughly only 30-40% and the game fps are bad,
also mostly between 30-40 fps or lower. Enabling or disabling graphical
settings doesn't make that much difference when it comes to fps or gpu load.

Enabling d3d_perf debug option shows issues with buffer uploads/transfer to mem
etc.

There seems to be an big issue with nvidia cards and dx11 in wine :(.

Im sure the perf would be really good if the gpu would be fully loaded.

I think i will open another bug for that issues, cause imho it affects
different dx11 games on nvidia in the same way.

Cu,
Christian
