I cant get freesync to work at all, even when it says its enabled.

 

AOC U2879VF monitor, supports freesync and says its enabled in the OSD (plugged in with DP to DP cable), tried with and without monitor driver and also turning freesync off and on in the OSD. (4k desktop).

 

RX580 8GB graphics card.

 

Freesync says its enabled under AMD Radeon settings, Display (40-60 freesync range shown).

 

I've tried with and without vsync.  Creating game profiles and making sure it says freesync ON under the settings (also tried without a profile).  Limiting FPS with FRTC and also leaving it disabled.

 

The tearing is terrible and more pronounced compared to when I was using an HD7950 without freesync.

 

If I load up Project Cars 2, turn on my windscreen wipers I can instantly see a tear going straight across almost the middle of the display.

 

Legend

 

OSD = On Screen Display

DP = Display Port

FPS = Frames Per Second

FRTC = Frame Rate Target Control

 

Others have found a Firmware update for their monitors and had success (different model).

 

I've done a lot of testing and googling, but haven't had any luck.  Any advice greatly appreciated.

Are your drivers up-to-date? What sort of frame rates are you getting, including minimums? I'm not sure what could be causing that sort of behaviour. Does the monitor indicate whether Freesync is active in addition to being enabled?

Videocard and monitor drivers are up to date, only running windows 7 (im stubborn).  Monitor says its enabled, if I disable it under the monitor then it fully changes the game out of fullscreen and hear lots of ding dong sounds from windows finding new device.  On the monitor it shows thats its on or off and under the refresh rate it shows Vertical Frequency 'Freesync' while Horizontal Frequency doesnt' (just the KHz)

 

Without vsync I was getting about 90 fps, when I capped FPS with FRTC (to 58), it would display 58 which is in range, but it clearly wasnt working, with screen tearing still happening, the fps stayed very constant at 58.  Others have said that I need to do it like that instead of 60.

 

I tried changing desktop res to same as in game, checked a bunch of AOC sites for different countries to try and find a different driver, but they were still the same from 2015 :/ I tried windows update to see if it had a monitor driver, but it didn't show one.

 

Monitor is 4k at 60hz

Hmm, been doing some research and there are several things that can go wrong, but probably only finding the same stuff you have already. For a start, have you tried other games, or the Freesync demo?

Freesync Windmill demo works fine, but no games seem to, Project Cars 2 has a line pretty much through the middle somewhere, Men of War Assault squad 2 while scrolling around the map tears horribly.  Its not to bad in Project cars as I'm not moving the mouse around, but any game where the scene is changing quickly tears up the picture.

 

Kingdom Come Deliverance is terrible, but thats because it runs at like 30 fps :/ (out of range).

 

Farcry 5 benchmarks quite well at 3200x1800 rez, but ingame and moving the mouse/view around tears a lot.

OK, could this be something to do with genuine full screen versus a maximized borderless window?

I'd make sure games say fullscreen and not borderless or windowed, no luck my end so far.  A lot of the freesync problems on the net are linked to AOC monitors :/

Just strange that it works on the windmill demo but not in game. Because it should be completely independent to what's running, whether the demo or a game.

I've had some success... Its far from perfect.

 

To not get horrible tearing or stuttering I had to have settings as such:

 

DON'T use FRTC, DON'T use V-sync in driver or game.  DO use RTSS and limit fps to 58 ish, DON'T use any fps monitoring software unless ingame or the one in RTSS.  Freesync ON under monitor and in driver.

 

I had also used CRU to check on the Freesync range (40-62 default), didn't need to do all the custom res stuff others had done, just used CRU and edit range.

 

RTSS = Riva Tuner Statistics Server

CRU = Custom Resolution Utility

Interesting. At least you're having some success. What are the remaining problems?

Pretty much one tear that isn't a perfect matchup, going horizontal.  It is noticeable in Project Cars 2, windscreen wipers make it really stand out.  No stuttering anymore.

Have you tried using the driver framerate limiter?

I'd get a big build up of stutter with the driver framerate limiter (might of been fraps), but using Rivatuner server statistics Framerate Limit worked better without as many hiccups, it also has an fps counter.

 

I'm looking into using Scanline sync now in conjunction with frame colour indicator (RTSS options), which can move the line that is seen when tearing to a less noticable part of the monitor.  From what others have said I use a value that is 90-98% of my vertical rez, so then the tear line is down the bottom of the screen.

As far as I can figure, that one tear should be happening between frames instead of in the middle – it's like something is delaying the update so that instead of happening in the blanking interval it is happening part way through the refresh...
