Question G-sync issue

[KIA_PETE]

If i turn g-sync on my screen tears a lot at 165hz
I prefer a smooth image more then frames so to speak
if i turn v-sync on too it caps at 157hz, shouldn't it still cap at 165hz? (uncapped my pc does 300fps, so not a performance issue)
is there an issue with my monitor?

Hey there,

Please list your full PC specs, including mobo, CPU, GPU, ram make and model, monitor (exact model).

G-sync range is 0-144 for Nvidia, and 48-144 for Freesync, IIRC

What happens when you cap the HZ/FPS to 144, still tearing?

Its a 144hz predator monitor OC to 165hz
@ 165 and 144hz it stutters and tears. V-sync on its fine caps at 157hz but I'm wondering if v-sync is highlighting an issue.

Tearing imageThe picture is at 144hz g-sync, no v-sync (phone camera makes the image a little worse then it actually is, the image quality is good irl but tears)

i7 8700k @4.6ghz
Corsair VENGEANCE LPX DDR4 - 32gb @ 3600mhz
EVGA 3080ti
gigabyte gaming z370 gaming 5

I am in the process of buying a new PC i know my gpu will be bottle necked.

G-Sync range is dependent on the monitor and the low end is not zero. It is 40FPS on older G-Sync hardware, possibly 20 on newer ones, been a while since I looked it up, below that threshold it switches to Adaptive V-Sync, ie doubling frames to maintain image smoothness at the expense of high latency.

G-Sync has two main operating modes.

G-Sync + V-Sync will operate G-Sync through its potential range but cap the max FPS to the refresh rate.
G-Sync + V-Sync off will operatate G-Sync through its potential range and then disable past it, you would be seeing your 300FPS again in that case.

I always recommend running a 165hz OC monitor at 144Hz, usually the LCD has better ghosting and other characteristics when it isn't overclocked. So don't run a G-sync profile of 144hz with a 165hz refresh. Set both to 144hz, or 143hz for G-Sync.

You did not list the monitor, so not sure if it is a G-Sync monitor or G-Sync compatible, FreeSync monitors tend to have more limited VRR ranges as mentioned by Roland. If you exceed those ranges, it may not behave correctly.

yeah sorry its a G-sync monitor.
weirdly at 300fps what i've not tried before its fine. G-sync only.

See https://blurbusters.com/gsync/gsync101-input-lag-tests-and-settings/14/

The tl;dr is you need the following for G-Sync to work optimally:

• Set a driver wide frame rate limit to 2-3 FPS below the refresh rate
• V-Sync on in the drivers, not in the games. If it's enabled in the games, turn it off
• Use fullscreen exclusive only modes

Deleted my reply as i just got to the part where its explained. That thread is huge. Thanks


Reflex* Settings:

*This setting is considered Low Latency Mode’s replacement, and will override it, regardless of what LLM is set to in the NVCP.

• If framerate does not always reach or exceed refresh rate, and Reflex is available:
  Set Reflex to “On” or “On + Boost” (“Boost” ensures the GPU doesn’t drop below its base boost clocks, similar to NVCP “Prefer maximum performance”). When combined with G-SYNC + NVCP V-SYNC, this engine-level limiter will 1) automatically limit the framerate to ~59 FPS @60Hz, ~97 FPS @100Hz, ~116 FPS @120Hz, ~138 FPS @144hz, ~224 FPS @240hz (etc) whenever the framerate can be sustained above the refesh rate, and 2) dynamically monitor and limit the framerate whenever it can’t be sustained above the refresh rate to prevent the extra pre-rendered frames that would be generated in an otherwise GPU-bound scenario.
