I just got a RTX 3080 (12GB) and I'm playing many games in great performance in 144hz (index) like Half Life Alyx, Zenith, Beat Saber.

But some games are not doing so good, like Pavlov and Star Wars Squadrons which are getting between 60-110fps (even in 120hz sometimes). 

Can anyone help me fix the performance of these games and any general tips to help with these issues.

I have11th Gen Intel(R) Core(TM) i9-11900 @ 2.50GHZ processor and 16gb of ram

Certain games I notice which are stable at 144hz can have a bad level or menu which drops the frame rate to anywhere between 90-120, is it still worth keeping the settings as it if if the performance is perfect (both smoothness and visuals) otherwise?
