The case that this is true is only if you don't have an Nvidia GPU or don't play D3D12 games.

I tried it, discovered that Nvidia has a known regression that causes anywhere up to 25% lower performance compared to Windows in GPU limited games in D3D12, and immediately went back to Windows.

I'll never understand why people keep championing Linux for gaming when it has such a severe regression on the most common gaming GPU vendor. Steam says 75%. An Nvidia employee even stated that the fix is not trivial so they're not committing to a timeline for a fix. This is a year+ old issue. They're never fixing it because it doesn't affect CUDA.

Add it to the list of the death by a thousand cuts of Nvidia as a gaming powerhouse. I would have said that they would have fixed it eventually to be chosen by Valve for a Steam Deck, but they’re gorged on AI money at this point. I don’t think they’re the future of gaming GPUs at all. They’re very slowly abandoning the market through those cuts.
