Is there any evidence that running under Rosetta impacts GPU performance measurably? Shaders are compiled on the fly for a given GPU so draw calls coming in from native vs emulated shouldn't have a big impact unless the CPU is the bottleneck.
GPUs are usually the performance bottleneck at 4k so Rosetta may not even have a measurable impact on framerate for some of the tests. Beyond that, what games are out there that have otherwise identical implementations that run on Windows/x86 and MacOS/Arm?
Why compare games at all? It is a really common use of GPUs so Apple claiming just "faster" rather than "faster in X use case" or "more FP computations per second" opens them up to gaming comparisons.
