How much is the speed drop from translation using Proton? Is it so big or just small? Hows the performance of cartoonish Windows only games? And whats your hardware and how much is the price? I’m sorry but I cannot test it myself because I’m still on my mobile. Can you also tell about how many games are compatible with Proton? What about non-popular games?
Games that run on Linux are about as fast on Linux as on Windows. In fact they tend to run a little faster on Linux.
Use AMD CPU and AMD GPU for the smoothest experience.
AMD CPU is more reliable, and Radeon graphics have the best support for Linux.
It is estimated that around 12000 Games work on Linux, or about 90%. For specific game compatibility you can always check protondb. Notice though that some games that have native Linux versions are also on ProtonDB, so you should check on the steam client first if there is a native Linux version.

PS ProtonDB state the number of games that are verified to work as almost 9,900, and playable as almost 30,000 😎
But Platinum or Gold rated games are only 60%.
Personally I generally check ProtonDB before buying a game, but it’s been quite a while since there was something that didn’t work.
