HI
“fixed refresh rate”
Do you have information about?

Is it correct that G-Sync does not work when I use this?
In-game [frame limit release mode]
When it comes to monitor technology G-Sync, 100-600 FPS was also released.

[fixed refresh rate]
When I activated the League of Legends with this function, 300FPS was fixed.

Hi, maybe i’m misreading or misunderstanding the graphs/article but there is no downside to just using G-Sync ON + V-Sync OFF + No fps limit?

G-sync would activate when below 144fps and then ‘de-activate’ above 144? Causing no input lag?

I know that for the lowest possible input lag, you want to find the highest framerate your system can achieve an average of 95-99% of the time without maxing your GPU usage and cap your framerate there with an in game limiter, but what do I do to achieve that in a game like Warzone where my FPS can be as low as 140 in big open areas or as high as 240 when inside a building or small area?

My CPU and GPU usage always seem to be very high at 85-97%. I have an i7 9700k and 1080ti, playing on a 240hz monitor. The game seems to be poorly optimized so I’m struggling to decide what to do.

When I play DOTA 2, my fps is all the time at ~117 because i capped it, but at the end of the game, when match finishes the base gets destroyed and i get a FPS DROP from ~117 fps to 80-90 fps and my game STUTTERS, is it normal? i am playing with g sync, vsync and fps cap, i thought gsync is supposed to GET RID of stutter or I do SOMETHING WRONG?? during the rest of the game everything seems ok

i am using:
-nvcp: gsync on fullscreen, highest refresh rate, vsync let 3d app decide
-dota2: vsync on, fps max 117 (120hz monitor), highest video settings
-latest drivers, gtx 1070, monitor aw3418dw

I typically prioritize input latency and thus normally run with G-SYNC but without any framerate limit or V-Sync, which causes some tearing at high framerates. I initially thought that Fast Sync eliminates tearing but introduces some microstutter, and that was all, making it a viable option in combination with G-SYNC, and the rest depends on preference (with G-SYNC: none = tearing, V-Sync + framerate limit = higher latency, Fast Sync = microstutter). However, if I’m reading this correctly, even G-SYNC + Fast Sync without a frame limit isn’t recommended because it limits the framerate to something lower than the monitor refresh rate, or runs starting at that slightly lower framerate?
