Just a question: how to deal with class linkage
Hi guys,
I noticed huge FPS drops on DCS with DXVK. The same map on windows gives me 60 FPS, whereas under Linux / dxvk 9 FPS. With 100% GPU usage. The log is flooded with class linkage isn't supported, so my guess is that those shaders cause the FPS. Is there any way to get around that? Since dxvk doesn't support class linkage?

What is DCS?
I'm not aware of any game requiring this feature, and if this one did then it would most likely not work at all. Some games pass an empty class linkage thing around which explains the error messages, but probably unrelated to your issue.
Though the inferno (Caucasus , Marianas, Sinai to be specific).

Is there a way to get data to see why it takes so much GPU (100% on linux and 66% on windows)? Can I somehow debug things?
Unless you're using an FPS limiter or VSync, 100% GPU - utilization is the best case scenario.
