Hello, first of all I'm sorry if I'm posting in the wrong place, if I am asking you to redirect or delete this post. Secondly, I'm sorry for my lousy English ... Let me tell you about the problem: I have a LG 29UM68-P monitor and am trying to choke on using g-sync. The riva tuner is marking that the games are running at 60 fps and the frametime is stable at 16.6 but I do not feel the flow of 60 frames at all times, there are times that it runs fluidly but in a few seconds I'm already starting to have the feeling that the frames are not flowing as they should and are not ... I already configured g-sync in the panel of nvdia, I already activated freesync in my monitor already tried to use it in 60 and 75hz, I formatted my windows 10, I already tried to use the last two drivers of nvdia I tested in games with direct x 11 and 12, but nothing solve my problem. Would anyone have an idea of what might be causing this problem? Thanks.
I have the same monitor, latest drivers work fine with this monitor. Here's how I setup to get it working butter smooth. Disabled Freesync on the monitor OSD. Go into Windows Safe Mode and use DDU to remove drivers. Disconnect the PC from the internet in order to stop windows downloading drivers. Install newest available driver. Reboot PC. Enable Freesync on monitor OSD. Then I go to the NVIDIA Control Panel and set G-SYNC to Fullscreen and Windowed Mode, check the box to Enable on this monitor model. I use Afterburner + RTSS and lock my FPS to 72 and set V-SYNC ON globally on NVIDIA Control Panel, disabled inside the games options. With all this I get stable 72 FPS in all games and really good frametime with no tearing and low-to-none input lag. Works flawlessly here in 75 Hz.
on prevous drivers I had to do the little trick to make it to work, there was some issues, but on the newest one 418.91 so far its working. The thing was that montior even when gsync compatible enabled in drivers and in monitor setting it just drops frame (good way to test it is to go website testufo) The trick is when you are on that website, with gsync enable in drivers and monitor see if it drops frame if it does just stay on that web page and go into monitor setting, and just toggle Freesync off and then agein on. after the blinks the testufo should be smooth. On prevously nvidia drivers the issue persist, let say you start computer and on 2-3 boot the problem was on 2 of 3 so I was really pissed. Now with 418.91 so far so good, no problems seems that they solve it. GTX 1070 with the same monitor LG 29UM68-P
Nvidia really needs to make it obvious that its better to use their vsync option when using gsync or freesync.
@Brenno When using GSync, when it's at max refreshrate and VSync enabled, the monitor disables VRR and just uses VSync. When the fps dips below that, VRR is enabled, and you will get a stutter as it switches modes, and will do so again when max is attained. This is why you use a frame capper to prevent maxfps, and keep VRR enabled. Gameplay will then be hesitation-free.
Hey man, a question: When you use Freesync on nVidia or G-Sync for that matter, do you need to keep the v-sync on the control panel? Cannot you just disable it and limit the fps with RivaTuner and forget about any form of v-sync? Since you are already using G-Sync.
VSync will still do frame timing compensation to prevent tearing in the VRR range. USe VSync enabled in NVCP, and disable it in game.
Unfortunately today when playing some games I have again the same problem again ... I do not understand what may be causing this sttuter.
There's a driver bug where the driver will not set the timings for VRR properly, and you will get hesitation and/or tearing and dropped frames. Solution: turn off monitor, wait a few secs, then turn back on. When the monitor is re-detected by Windows, the drivers will restore the timings info. You can also disconnect monitor and reconnect, or use restart64.exe from CRU's package if more convenient.
If you are using EVGA Precision in any form it is definitely the culprit. Just turn it off and watch the stutter disappear!
