People writing CUDA apps don't just want stuff to run, performance is an extremely important factor else they would target CPUs which are easier to program for.
From their readme: > On Server GPUs, ZLUDA can compile CUDA GPU code to run in one of two modes: > Fast mode, which is faster, but can make exotic (but correct) GPU code hang. > Slow mode, which should make GPU code more stable, but can prevent some applications from running on ZLUDA.
Rosetta 2 runs apps at 80-90% their native speed.
Not at all, the performance hit was in the low 10s %, before natively supporting Apple Silicon most of the apps I use for music/video/photography didn't seem to have a performance impact at all, even more when the M1 machines were so much faster than the Intels.
