But it is also rare cases where a a few percent points actually make a huge difference. Remember when reviewers are doing benchmarks they're generally using a standardised test suite with uncapped framerates. For most people they would be perfectly happy to hit a target framerate, or if they really want to play uncapped they would first reduce a few graphical setting to archive good performance (most of time with imperceptible changes in the graphics). It is rare when the performance of the game is so tight in a hardware that a few percent points actually matter.

To give a particular example, I started playing GTAV on Windows after building a new PC since I had no spare drives. After finally installing Linux I decided to try GTAV on Linux just to see how well it would run. And it runs amazingly well, and yes, it runs a few percent points slower than Windows, but the only tradeoff I did was slightly increase FSR4 and the game still looks amazing. I didn't really notice any graphics issues, especially not during actual gameplay (if I stayed at the same place and started to nitpick I could notice differences).
