Basically my issue is simple. Almost every game that works in DX12 is jerky with G-Sync enabled. I've got Acer Triton 500 - i7 8750H / RTX 2080 MAX-Q with 144Hz 1080p panel. Any game in DX11 with G-Sync enabled play smooth. But not the DX12 titles. Just take a look at this side by side comparison in MW: https://youtu.be/-Pkz0Gb5ni0

Don't bother for windowed mode on the right, I have G-Sync enabled only for fullscreen applications so turning in windowed mode equals G-Sync off.

I honestly don't understand it. I thought G-Sync is only about varying display refresh rate. How instead of a super smooth image I'm starting getting totally opposite?

It's still a thing on my laptop

Shadow of the Tomb Raider, take a look:

When I'm in DX12 and G-Sync is ON I've got horrible stuttering. If I switch to DX11 everything is smooth. Also, no stuttering when G-Sync is OFF in DX12.

Okay, case solved. I switched from a balanced power plan to performance and it solved the stuttering issue. Took 2 years to understand this.

The issue is back, in some way. Now i've got another laptop with G-Sync screen. It's Redmi G Pro 2020 with i9-12900h and geforce 3070ti and 240hz panel. The best possible example was captures in BF2042, take a look:

G-Sync is set to work in fullscreen only so when BF2042 is in fullscreen i've got strange hiccups, and if i switch to windowed mode (where g-sync is not working) everything is smooth.

I've noticed same stuff in Diablo 4, but hiccups happens less often, but still they are absent in windowed mode.

maybe it's doing copy through igpu? what does gpu util show for the integrated when running full screen?

I think it's copying over igpu.backrooms
