G-Sync Users, need a bit of help!

[Jestahr]

Just trying to work out if I have a faulty monitor. I've been getting varying results with gsync, and recently noticed micro freezes with it enabled in some games (amongst other little problems).

Currently I have it set via NVCP:

Global Settings V-Sync on
G-Sync Enabled

For some games, such as CSGO I've set a custom profile to disable v-sync (which works). The problem is, particularly in CSGO I'm getting micro freezes of 1-2 seconds randomly but consistently.

What I've noticed recently, that I hadn't noticed before, is starting any game using Gsync my monitor flickers between graphical glitch screens that resemble a faulty gnu artifacts. These screens can flicker for anywhere from 1-3 seconds. In particular I notice it when starting CS:GO or StarCraft 2. It's similar to running games at a non native refresh rate, albeit in this instance there are colors and distortion over the screen. I can resolve this instantly by disabling G-Sync.

So I wanted to work out if this graphical gltching is unique to my monitor (AOC G2460PG) or if it is something noticeable by all users of GSync.

So if someone can copy these settings and test with CSGO I would appreciate it!

Nvidia Control Panel use 3d settings. Global Settings set to VSync On
Create a profile for CSGO. Set VSYNC to OFF.
G-Sync Enabled
Disable V-Sync ingame CSGO.

Fire up the game and pay attention to any weird flashing/graphics on startup. They also appear when alt tabbing. Also noticed in StarCraft 2 the same thing.

The nvidia CP has to be set to g-sync i think under the v-sync settings now. The g-sync tab obviously also set to on. Then v-sync off in game as well to work correctly normally now. Unless you set it to g-sync in the 3d settings you aren't using g-sync with the latest drivers unlike before. Also make sure g-sync is set to fullscreen or windowed version depending what you are doing. Plus set a fps limit under 144 to avoid lag.

I don't have CS:GO so I can't test your settings, but I can provide some information which may be useful to you.

Firstly the Nvidia settings. Change the global setting to let the application decide, then set your games to V-Sync disabled in game. G-Sync only works when V-Sync is disabled.

The screen flickering is an inherent flaw of G-Sync so it seems. It can only match the refresh rate within a certain range (can't remember the exact values off the top of my head). Some games use a static image or at least a very low frame rate when loading a game which is outside of the G-Sync range resulting in flickering on the display. Either a case of you live with it or disable G-Sync.

Similar sort of things happen when tabbing out of games. Since G-Sync is enabled in full screen mode by default, the monitor has to disengage the G-Sync module when tabbing out and enable it again going back in resulting in the same behaviour.

If you're still having problems with stuttering in CS:GO you can try using a frame rate limiter just below your monitor's refresh rate.

Hope this helps.

Thanks for replies.

Actually gsync works with vsync on from the nvcp (disabled ingame) ON = 144fps cap / OFF = gsync on until 144fps, then it runs like a standard no vsync screen.

I'm mainly trying to work out if my module is behaving normally when enabling on game start ups/alt tabs.

It used to just go black and flicker. However I now notice it fills all these distorted graphics which looks similar to a damaged GPU. Likewise these micro freezes were not something I noticed until the last week, and they seem to get more regular. At this stage I've tried everything to troubleshoot, the only fix seems to be disable gsync which makes me concerned!

If anyone can confirm how their screen behaves in the above scenario it would help me work out if mine is behaving abnormally, and might go some way to explaining the other issues I've noticed.

So far the only games I can say I've seen a big improvement on fluidity are GTA V and WoW. Haven't tried them again since I noticed the problems however as they are now u installed as a result of formatting to try and fix the freezes.
