Can't use 'native' as an excuse if your argument is it runs games better. Can't blame hardware if you're ignoring recommended specs from the developer. Can't say it runs the exact same if you have no evidence. -It's just propaganda. Can't blame nVidia for not being open-source when they lead the industry and profit from trade secrets.
I switched to linux from windows almost a decade ago. Took hours to get my video driver working properly. Worked modestly well, but I hated windows gaming so I didn't do much prior. Takeaways: Linux runs like a beast, windows runs like a beast wearing a full body cast, Linux gaming with the addition of proton and additional support is nearly a flawless experience. Thirdly, Linux is free, enjoy your bloatware chumps, for a few measley fps I get a free operating system that you can literally build a career around with all of the quality free education online. Windows you better buy that Damn how to book.
Spoken like a true Loonix evangelist, how come I'm not surprised?
