Marvel Rivals 100+ FPS but snappy

Greetings everyone. Been playing Marvel Rivals on GFN for a week now and in the first 4-5 days it worked silky smooth, but now even though the game is (sometimes) reaching over 100 FPS, the game still feels a bit snappy and choppy. It doesn't feel like it has over 100 FPS, it's not looking smooth.

I tried messing with the graphic settings, set everything on low with V-sync off, DLSS, Resolution Mode on Performance and Reflections off.

The game easily gets into the 100+ FPS but as I said, it doesn't feel like it. The image is a bit snappy. I think the correct definition for it is frame skipping or something ? I don't know.

Thing is, I don't know how to fix it and it's been affecting my performance in the game a lot.

I play on the Performance/Priority tier. I would upgrade to Ultimate if that would fix the issue, as I'm loving this game to death, but then I'm gonna get the 100 hours cap (which I easily go over even with a full time job). I'd like to refrain from upgrading for now as I'd like to enjoy unlimited playtime a bit more.

Anyway, back to the subject. Has anyone experienced anything similar or knows how to fix it ?
