Wine has to translate Direct 3D to OpenGL but current Wine does this with a single CPU core. CSMT (command stream multi-threading) is code the developers have been working on that speeds this up by using multiple CPU cores for a dramatic speed increase. For whatever reason the code never made it to Wine, but somehow made it to CrossOver by codeweavers who fork Wine.
So some people take Wine and patch it to get CSMT.
You just type regedit in terminal and you get a familiar regedit like in Windows. Then just do exactly what this picture shows for CSMT enabled. You don't have to do anything else. You need to create a Direct3D entry most likely.I opted to just use your code, then started reading through the links. I'm supposed to:
I'm not in Linux just now to check, but I couldn't find the WINEPREFIX registry.
As for StrictDrawOrdering, I find it's listed twice, one is enabled and one is disabled. By checking the boxes at the side of those options, I was unsure what they would do, so just left them.
Oh and! when following some of that code, and installing winetricks, I got some big run on errors again, all connected with Radeon. I didn't PrtSc it, but it looked very similar to the bunch of errors I got when installing kernel 4.0.
