[Linux] FPS locked to second monitors refresh rate

I'm currently running NS2 fine on Antergos with Nvidia 396.24 but the only nagging issue I have is that NS2 uses my main montior but locks the FPS to my second monitors refresh rate of 60hz. If I disable my second monitor my FPS are unlocked up to 165. It's really annoying having to disable a monitor everytime I game. Any ideas on how I can either fix it or force 165hz on NS2?

Thanks

Are FPS or HZ locked? I thought these are two complete different things since I can have 200 FPS but with 60Hz I don't see much more on my screen.

I'm not using Linux, but in my Nvidia Control center I had to do 2 things in order to have the correct HZ for my game (even with 2 screens - but I don't use that anymore because the second screen drains to much CPU/GPU Power)

a) I predetermine that the Resolution I play with has for example 144hz in the Nvidia Software (but this seems to be a bit wonky)

or

b) I already change the Screen to the Resolution I play ns2 in and change the HZ already to 144hz (I recheck that via my Screen in the Menu)
When I now Start NS2 in that screen the HZ stay at 144hz and are working correctly

They are two different things but if my monitor can redraw the screen 165 times a second and the GPU can produce 165 frames per second then I get maximum smoothness. Going higher than 60 FPS on a 60HZ monitor doesn't get this benefit and typically just tears (without Vsync etc..)

As far as I know some games lock FPS to the same HZ as there isn't any point going higher. for me having 60 FPS feels drunk and laggy.

When checking Nvidia settings my monitor is set to 165hz when playing but NS2 is still locked at 60 FPS. This seems to be a Linux issue for me as on Windows I have no problem.
