Hi

My monitor feels better and somewhat more responsive with g-sync on. I could'nt literally hit anything without it on, and prefered gaming on my samsung g7 in csgo. I'm around 3000 elo, and everytime i tried playing on this monitor my shots just wouldnt connect.

My question is, if i activate the gsync/vrr on my monitor - does the input lag only rise from 1.7 ms to 1.8? Then there's no disadvantage to just activating it. I mean whos gonna notice the difference in 0.1 ms lol.
and also, i heard if i activate ULTRA in the low latency setting in NVCP it automatically caps the frame for me to reduce input lag. But this doesnt happen on my pc. Should i just cap it in-game -3 to be safe?

0.1ms is well within their device's margin of error, especially from run-to-run test variance. It basically means there's no difference, and there usually shouldn't be where display processing is concerned; VRR operation requires a more instantaneous scanout than non-VRR operation, so VRR-capable monitors usually must have less display processing.

As for any differences over 1ms you see in rtings tests between VRR and non-VRR is probably their device picking up tearing artifacts with the latter, which can reduce latency further over tear-free single frame display (a limitation of the max refresh rate with tear-free VRR, not a limitation of VRR itself). That, and in rare cases, it's possible the firmware on non-native G-SYNC displays may theoretically handle display processing differently in VRR-mode.

The auto cap only works with G-SYNC + NVCP V-SYNC + LLM Ultra, and only with some games (the combo doesn't work in DX12 and Vulkan games at all). It's not guaranteed, so you'll have to check on a game-by-game basis if you want to enable and use G-SYNC properly. So if the Ultra combo doesn't work, yes, you'll need a minimum -3 FPS limit of your current max refresh rate to keep the framerate within it, since VRR only functions inside the refresh rate.

Thanks a lot! appreciate it.
