I wonder how you fixed the environment issues that i had on my version ? It was still glitchy for you on the old firmware though so yeah...
I saw pcercuei post about it : how much faster is the 3D driver ? Because he said that in some cases it could be slower.
In any case, i hope that means i can push Supertuxkart & others (Lugaru) as stable, because they either run too slow or with glitches.
There might and might not be some regressions. It's hard to know because not everything draws correctly on the older firmware. When both are rendering correctly, new firmware seems to be faster by a measurable margin.
OpenGL ES 1.x apps I am still not sure, the iortcw tests are inconclusive because the old fw was botched as hell.
In terms of SM64PC, the new firmware works better and performs better, from the quick tests I've done I haven't seen any framedrop, while the old fw did fall below 30fps sometimes on bo-omb field.
Also I have no idea what changed. There are some changes as to how shaders sample things and new vertex attributes - I am not experience enough yet to entertain many guesses here, but it's still broken as hell, textures aren't being sampled correctly, etc.
