I have an AOC 24G2U5 75Hz which supports FreeSync but i still have tearing when playing games. G-Sync is enabled in the Nvidia Control Panel. Plz help

PC Specs:
Ryzen 5 2600
A320 S2H
2X8GB 3200Mhz CL16
GTX 1660 Super
ADATA SX8200 Pro 1TB NVme
AOC 24G2U5 75Hz Connected via DisplayPort 1.2

If I was to guess you need DP 1.4
 
Try V-sync on
 
What games are you playing, at what resolution, and what graphics settings in games?
 
What about HDMI? Will G-Sync work with it?
Depends on the monitor at least for real Freesync I can do 100hz via HDMI vs 144hz on DP
 
Not all freesync will work with gsync..
 
Does the monitor support Gsync?
I thought it had to support Vsync Premium.
 
He said that G-Sync is enabled so i assume it is supported :confused:
This monitor is not listed as g-sync anything as per the official list:
So it's at most Freesync/AdaptiveSync.
If tearing is a problem, just enable Vsync or adaptive Vsync.
 
Do you enable GSync for just fullscreen or fullscreen and windowed? Sometime the game might not be fullscreen and GSync is not triggered if you set it for full screen mode only.

I have no problem using GSync on non listed display. Just use DP, set Freesync in monitor OSD and then enable it in nvidia CP and make appropriate adjustment like I said above.
 
Gsync is not a fix all for tearing. i have Gsync branded monitors, & the best Nvidia GPU's money can buy, & still games sometimes get tearing. i normally find ULMB or fixed refresh resolves tearing if Gsync doesnt cut it.

I got that but if he said it's enabled those are his words.

I am curious how many fps he is getting

You may enable gsync, does not mean it'll work. I can turn it on for my monitor and toggle between the three modes yet never actually works.

V-sync literally defeats the purpose of G-Sync/Freesync. The whole point is not having to use it...
 
There is misinformation in this thread about how VESA standard adaptive sync, aka AMD's Freesync aka NVidia's G-Sync compatible works.

You need to use a DisplayPort cable (1.2a or newer) if you have a GeForce graphics card. Freesync over HDMI is a Radeon thing at this time.

You may need to enable Freesync in your monitor's on-screen controls. If you're using an NVidia GeForce card, you'll probably have to open your GeForce settings and enable G-Sync for your monitor.

Turn on V-Sync in your game's graphics settings. With Freesync or G-Sync enabled, your monitor and your graphics card work together to adjust the monitor's refresh rate to synchronize with each new frame that your graphics card has ready. V-Sync is only going to slow things down if your game is running faster than the maximum refresh rate that your monitor can support, and at that point, isn't it fast enough?

LFC (low framerate compensation) causes the graphics card to double frames if your frame rate drops below the lower end of the variable refresh rate range that your monitor can support., So, if my monitor's variable refresh rate is 48 to 165 Hz and the graphics card can only manage 40 fps in the game that I'm running, the graphics card sends each frame twice and the monitor refreshes at 80 Hz.

rofl, u are clueless, Vsync must be turned on or you still get tearing

Utter DERP! The tech is literally meant to eliminate tearing and NOT need V-sync Thats literally the entire point...JFC...:banghead:
 
If you prefer not to run G-Sync with V-Sync, then chances are you might be running past 75fps in your games as G-Sync will not work when it is out of your monitor's 75hz refresh rate range. The internet recommendation to keep G-Sync working is 3-4fps below your monitor's max supported refresh rate. Theoretically you should cap your FPS at around 71 FPS to keep G-Sync working at all times.

Same goes if you drop below 48FPS in games if the lowest supported G-Sync minimum range of your monitor's refresh rate of let's say for example 48Hz then G-Sync will turn off briefly as well until your FPS is back within range.

Hope this helps as well.
 
As a resident monitor connoisseur of TPU, I'll leave some lightning quick bullet points here.

* When G-sync and Freesync was introduced, both Nvidia and AMD recommended V-sync On as well. Because guess what, they don't work if you're getting 160 fps in a 144hz monitor.

* Tech savvy people rightly noticed that V-sync introduces input lag and so devised framerate limit with Rivatuner Statistics Server or RTSS.exe that's part of MSI Afterburner. You set fps limit 2-3 under the monitor refresh rate. These days some games support fps limit in-game and Nvidia & AMD have introduced driver level framerate limiters.

* G-sync works only over DP. Version doesn't matter. Freesync works over HDMI and DP both.

* All Freesync (or G-sync Compatible now that monitor brands wanna suck up to Nvidia) monitors have a range. OP's is a pitiful 48-75hz, a mere 27hz window where Freesync works.

* LFC or Low Framerate Compensation is a technique where Freesync works when FPS drops below the range. Say I have 48-240hz Freesync monitor. When a game I'm playing drops below 48 fps, LFC kicks in and doubles the fps. 48 fps is fine but 47 fps becomes 94 fps or some such shit.

* LFC kicks in auto in monitors with 2:1 or more ratio between lower and upper range. e.g. some 30-60hz Samsung TVs, usual high refresh rate monitors, some lucky 75hz monitors that were 30-75hz.
Your 48-75hz and my 40-75hz monitors are outta luck. We have a pitiful 27hz and 35hz window.

* Notice how I didn't mention G-sync in LFC point. Because there's no public info about similar tech in Nvidia's side. Pure G-sync (the module ones) at least usually claim to do as minimum as 0 fps iirc. Since the modules replace the scalers (chips inside monitor) maybe it's true, maybe not. I don't think I've heard LFC in Nvidia's drivers for the G-sync Compatible (or Nvidia co-opted Freesync) monitors.
