Fps drops when i use Fractional Fps

[lansta]

Hi
When im using Fractional fps ( 240/1, 144/1 and etc.) my fps in game drops from 1500 to 100 (minecraft), its not my pc issue, because when im using Common fps (60), all is good, theres no any fps drops.

I tried to update gpu drivers, change obs version to old one, change obs settings but nothing helped.

What should i do to fix this? I need to record in high fps for videos but i cant, really need to solve this problem.
(my pc: rx 6500xt, r5 5500, 16gb ram)

It actually is your PC, because you're overloading it, that's why your ingame fps takes such a severe drop.

You don't actually NEED to record in high fps

I need, because i need smooth video in high fps, and also i need high fps because when i slowdown the clip in vegas, it looks like 30 fps

Does that mean I can't fix it? Cuz my friend with almost same pc (6500xt, r5 5800x, 32gb ram) has good fps while recording using fractional fps
