Well, that's a tricky question.

I use https://github.com/FunkyFr3sh/cnc-ddraw to run old 2D games. It supports
multiple rendering backends.
> GDI / OpenGL / Direct3D 9 renderer

Before this commit, OpenGL renderer performed perfectly fine. After this
commit, OpenGL renderer performs even worse than GDI.
Direct3D 9 renderer is seemingly unaffected, but it requires DXVK.

I'm not sure about other OpenGL apps. I would try to find something easier to
test on. Maybe it's cnc-ddraw exclusive issue after all.
