Gsync not working on multi-monitor setup and weird framerate issues

I noticed that non-native games (both wine and proton and different versions) while initially starting off good sharply drop of in framerate-continuity, depending on the game it would take between a few seconds and maybe a minute to get almost unplayable. The framerate counters in the corner keep displaying significantly high numbers, in the hundrets or even thousands, but the actual gameplay I was experiencing after that initial good start would compare more to 10 to 25 fps roughly estimated.
Messing around with graphic settings and enabling V-Sync only made this issue more confusing, it would lock to 60 fps on any game (proton, proton custom from the aur, wine and linux native games like cs2).
Additionally it would have severe output delay (roughly 0.5 seconds). I should mention that I have 3 screens, the main one being 165 Hz, the others 60 and 75 Hz.
Thinking that it might be locking to the refresh rate of the worst monitor, i disabled the other 2.
This actually worked, and I was correctly getting 165 fps constantly, and the output delay was completely gone, indicating that G-Sync is working correctly.
Next I tested only plugging the 75 Hz Monitor in again, after that it locked to 60 hz again.

I have set the 165 hz screen as my primary in the kde display settings, and tried pretty much every option in the nvidia x server settings.

Any ideas on how to solve this?
