Legion 5 Pro 2021 G-SYNC causes stuttering in games

I've seen other posts regarding this issue, seemingly happening with "older" panels.

For example, in Battlefield 2042 if I play without gsync, it's smooth as butter with some minor tearing visible if I look carefully (freesync). But once I turn G-SYNC ON, the game feels like it's running at 30 fps, it is responsive but very framey and stuttery. This also happens with COD MWII.

However in games like Tarkov or World of Tanks, G-SYNC doesn't cause such issue. It's weird.

Is there a fix to this? I remember it was smooth as butter before, but now (probably due to a driver update) it causes lots of stutters. Anyone else?
