That's fair, but I think it's a different argument. Benchmarks are an easy solution to the problems I presented. Your situation is a bit more niche, and while there should be a way to identify and track more niche hardware/software setups, I'm not sure a casual review saying "runs great on my rig" is exactly the place for it.

Conversely, I would think people who do use niche gaming setups (like gaming on Mac, for instance... or Linux) would be more than happy to share the details of their setup to help others as they would want to be helped.
