G-sync issue
G-sync issue
If I enable g-sync my screen gets very choppy at 165hz. I like smoother images rather than just frames. If I turn on v-sync it caps at 157hz, shouldn't that still keep the frame rate around 165hz? (My PC runs at 300fps, so it's not a performance problem.) Is there a problem with my monitor?
It's a 144hz predator monitor OC for 165hz. At 165 and 144hz it stutters and tears. V-sync works fine at 157hz but I'm unsure if it's pointing out a problem. The image quality is still good, but it tears.
The G-Sync range varies based on the monitor, and the minimum is not zero. On older hardware it’s around 40FPS, possibly 20 on newer models. It hasn’t been checked in a while; below this limit it switches to Adaptive V-Sync, which doubles frames to keep the image smooth but increases latency. G-Sync offers two main modes: G-Sync + V-Sync and G-Sync + V-Sync off. The former extends G-Sync’s range but limits FPS to the refresh rate, while the latter runs G-Sync within its potential range then turns it off afterward, restoring full FPS. I usually suggest using a 165Hz monitor at 144Hz for better performance and fewer ghosting issues. Avoid mixing a 144Hz refresh with an 165Hz display. Set both to 144Hz or 143Hz if you want G-Sync functionality. Since the monitor model wasn’t specified, it’s unclear if it supports G-Sync or is compatible. FreeSync displays tend to have narrower VRR ranges, so exceeding them might cause problems.
Yeah, sorry it's a G-sync monitor. It's strange that at 300fps I haven't experienced any issues. Just G-sync only.
To ensure G-Sync functions properly, adjust the driver's frame rate cap to 2-3 frames per second below the display refresh rate. Enable V-Sync within the drivers but disable it in the games. Activate exclusive fullscreen modes.
I deleted my reply because I just reached the explanation section. That discussion is quite large. Thanks
Reflex* Configuration:
*This option replaces Low Latency Mode and takes precedence, even if NVCP settings differ for LLMs.
If the frame rate doesn’t consistently meet or surpass the refresh rate, and Reflex is enabled:
Adjust Reflex to “On” or “On + Boost” (“Boost” keeps GPU performance stable, akin to NVCP’s “Prefer maximum performance”). Together with G-SYNC and NVCP V-SYNC, this
engine-level limiter will automatically cap the frame rate at ~59 FPS at 60Hz, ~97 FPS at 100Hz, ~116 FPS at 120Hz, ~138 FPS
@144hz, ~224 FPS @240hz (and more) whenever the rate stays above the refresh limit, and
dynamically adjust to prevent unnecessary pre-rendered frames in a GPU-limited situation.)
