I have noticed that it has only 2 stars when trying to install on Big Sur.
When tried default installation using Crossover 20 game was randomly crashing with error:
00cf:err:d3d:wined3d_check_gl_call >>>>>>> GL_INVALID_ENUM (0x500) from glBlitFramebuffer() @ ../../../wine/dlls/wined3d/surface.c / 297.
Not sure how exactly I have managed to fix that but here is what I did:
- Installed Rift one more time but this time using 64 bit Windows 7 bottle
- Disabled trilinear filtering in Rift's options (this is what most likely got rid of this error).
