Help identifying Gsync/monitor issue (faulty monitor/gpu?)
Posted: 29 Oct 2018, 11:23
I've posted a few times about having input lag trying to use my monitor (XB252Q) and I am slowly getting somewhere but still I'm not sure what is happening with the settings I'm trying out.
I use Fortnite to jump in and out of because its quick and I can easily tell if input lag is present. (Always with vsync off in game)
So I set up the monitor exactly how the Gsync 101 tells me to and I have pretty big input lag, but at completely random times it goes away but never stays away. ( You can tell its not right because the movement isn't fluid with the mouse at all, the sens feels way lower and its half impossible to aim, it just feels completely off.)
I have tried forced vsync on and off in NVCP and also on no frame limiter in FN/ also tried the other limits and doing the custom 237 limit, its all the same input issue.
Now to the point where I have now figured out a setting which seems to make it feel way more fluid but don't quite know why..
If I turn the Vsync mode onto the default setting of 'Managed by 3D application' and keep vsync off in game it seems to stay fluid and feels way better.. But surely forcing Vsync off or on and staying under the refresh is the same as managed by the game with in game vsync off, so why is the other setting causing lag?
Also I found the input lag went away if I forced vsync off in NVCP but turned vsync on in game.
Also I have been having some issues with my pc, I can randomly hear a fan getting loud under no load, sometimes there is a rattling/virbrating sound with it. The PC freezes browsing Firefox and sometimes opening task manager and other programs. Still happens after Windows clean reinstall.
I have just recently read this can be signs of a faulty GPU, so potentially that is the problem?
Also my monitor has some kind of fault with a line of pixels randomly appearing on the screen, its only happened a few times but in Lagom pixel inversion test you can see it. I can't seem to find anybody else online with the same issue.
Sorry for the long post but I am pulling my hair out trying to find out whats wrong. I've not done this testing with gsync off yet, so it might not even have anything to do with Gsync but there is definitely something wrong!
