Very good that you mentioned the improvements are already in the R6xxx game drivers! I don't really do much with OpenGL anymore, but the couple of pieces of software I have do seem to run much better than earlier.
I don't think 72% is enough. If you look on Blender benchmark RTX 3090Ti have median score 6286 points, RTX 3060 2437 point. Radeon RX 6950 XT is even behind 3060 with only 2133 points. This is really sad. Best AMD GPU can only beat lowest Nvidia's RTX 30XX GPU the RTX 3050.
For us 3D hobbyist there is no other option than Nvidia.
