If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.
We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

Screen tearing
I've noticed I have some screen tearing when playing GZDoom. It's barely noticeable until I move only slightly. I've tried turning VSync on and off, but that didn't help. I assume it's something to do with the backend, but I'm not entirely sure. Any suggestions?
Re: Screen tearing
I vaguely recall reading that GZDoom uses adaptive sync. The cvar for it is "gl_control_tear". You could try toggling it with vsync on and see if it makes any difference.
Re: Screen tearing
I still dont understand why you dont redesign the vsync option instead of having that hidden cvar
Why not make the vsync option like this:
VSync: Off | Adaptive | On
That would eliminate this confusion.
If I see an option
Vsync : On
I expect it to be on and not adaptive

Re: Screen tearing
It can't be done like that because the behavior here is very different on different hardware, there's even a second hidden CVAR due to this.
