G-Sync+vsync question

Post by Insight » 21 Dec 2019, 12:04

Hello, I recently switched to a PG258Q 240hz G-sync, i currently cap my fps to 236 and use vsync from the settings in game, but i was wondering if it makes any difference to activate it from the NVCP (i see often it is recommended) i guess it depends by the game's optimizations but i'm not sure what's best to use. I Mainly play CS:GO, overwatch and apex legends. Thank you!

99% of the time it doesn't matter; the in-game V-SYNC option and the NVCP V-SYNC option behave the same when used with G-SYNC.

However, there are rare 1% instances where the in-game option may cause unexpected behavior. Regarding Apex Legends in particular, refer to one of my recent posts in another thread:
viewtopic.php?f=5&t=5903&start=100#p45157

I personally recommend using the NVCP option with G-SYNC, simply for those 1% instances, but it's not a hard and fast rule.

Hi, guys.
I am using XG270.
I have wierd 225 framerate cap with G-sync ON + V-sync ON (nvidia cp) + Fullscreen. Tried at different games and benchmarks.
If G-sync ON + V-sync OFF + Fullscreen or G-sync ON + V-sync ON + Windowed - framerate goes max (or 237 if i cap it via RTSS)
Is it normal for G-sync ON + V-sync ON + Fullscreen to be capped at 225 fps without capping it in nvidia cp/RTSS/game?

Tnx for reply.
Cheers from Ukraine )

Do you happen to have Low Latency Mode set to "Ultra"? Is so, that setting auto caps the FPS slightly below your refresh rate when using G-SYNC + V-SYNC. Set Low Latency Mode to "On" instead if you want to limit the FPS with another method.
