This is weirdly common; phone chipset manufacturers did it with phone benchmarks [0], VW with emissions [1], nVidia did it with 3DMark [2], Intel with the SPEC benchmark for its Xeon processors [3], etc.

When it comes to computer graphics, iirc it's pretty normalized now - graphics drivers all seem to have tweaks, settings, optimizations and workarounds for every game.

(As an aside, I hate that I have to link to archive.org, there's a lot of dead links nowadays but these are important things to remember).

Even Mesa has them: https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/uti...

Goodhart's law: when a measure becomes a target, it ceases to be a good measure.

Maybe hyperbole, but I think obviously they can't do this for literally every game, that would require huge personnel resources. At least looking at mesa (linked elsewhere), only ~200 games are patched, out of what 100k PC games? So <1%.

Well, pretty much every large AAA game launch complimented by GPU driver upgrade that adds support for that game. It's in the patch notes.

Mesa is a lot more conservative about this than the proprietary drivers.
