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?
If you’re ok with inexpensive entry level gaming performance, you could get one of the AMD BC-250 boards which is essentially a Playstation 5 for a couple hundred bucks. Last I checked all disabled CPU and GPU cores can be unlocked.
