I guess this can be considered a kind-of follow up of Abysmal OpenGL performance (RX480)
Basically.. I tried the my testcase on the following systems:
- Core 2 Duo E8400 + Radeon 7750: ~19 FPS
- Phenom II X4 965 + Radeon RX 480: ~25 FPS
- Core 2 Duo 6320 + GeForce GT 430: ~58 FPS
I believe I don't need any further explanation.
My educated guess is that gl commands aren't dispatched to a separate thread.
Instructions to use the thing shouldn't be any different from those contained in this last link.
