Terrible performance compared to windows on Arch with non-steam games on proton.

Hello friends! I am back with another issue.

Recently I have taken on the task to get non steam games working on Proton. I have noticed that the performance is significantly worse with them on Linux then on Windows. More frequent stutterings and such. 100 fps consistently on Windows vs linux which it dips below 50 fps. Other "better performing" non-steam games get consistent micro stutters. I am using native steam because the flathub version because after installing dependencies with protontricks the game still would not launch.

The only possible thing I can think of is the games are on NTFS partition (yet steam regular games installed on it run just dandy). I dualboot with windows and access this particular drive between both os'. I am at a complete loss, any help would be appreciated oh Linux brotheren and sisteren.

Thank you!

(also the games drop audio consistently as well sometimes it wont come back unless I alt tab and come back to the game.)

EDIT: Hello everyone! thank you again for the help I think I have come to the conclusion that some of you suggested already. Wayland seems to be having the game perform significantly better than x11 but it still isnt quite up to par as windows. When I had tried it before I thought to myself "yeah this is better but it isn't up to par with my windows partition" so I kept searching for an answer. the conclusion I have come to is, I think this just comes down to the particular game being unoptimized. Thank you all for your suggestions! You all are truly moving mountains when helping people swap to this wonderful operating system. Hopefully one day I can get rid of my windows partition fully. (too bad I am a VR dweeb that needs windows for some applications to function 😭).
