How I finally fixed micro stuttering and screen tearing!
Been dealing with this problem for almost 3 years and I never understood what causes it, now I found a FIX that works globally.
Problem: Every game I was playing didn't feel smooth, my fps were uncapped all of the time, and G Sync or Vertical Sync off. This caused mismatch between my GPU and Monitor, which resulted in stutters.
MY FIX:
Nvidia Control Panel ---> Set maximum fps -3 of normal hz (If you have 144hz, set maximum to 141) - This step is pretty standard for g sync setups.
Open G Sync or Freesync from your monitor (this step won't work if you don't have a monitor with those techs) - Freesync works with Nvidia GPU too (I have a RTX 4070 Super) and I use Freesync.
Nvidia Control Panel ---> Set Vertical Sync to "Fast" (Really important step!)
Whatever game you play, turn on Vertical Sync from it's settings.
This made all of my games smooth; the only one who still acts up is minecraft.
Note: I don't even have the LOW LATENCY setting on, and there's almost no input lag. But might test it further.
My setup:
Ryzen 9 5900x (undervolted to 1.25V) RTX 4070 Super OC Windforce 3x 64GB DDR4 3200mhz Corsair 4000D Case B550 Gaming Plus Be Quiet 750W PSU
If you have any improvements to this fix write it down!
