V-Sync's broken on AMD card's

Forum rules
Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

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.

So... I rushed to see the vid_fps and... suddently it all works...
I cannot replicate what I just described above it works as expected (as it should), I didn't even rebooted the computer.
Very strange :/ I apologize then. I tried that many times before and it was always the same.

What numbers do you get when typing 'vid_fps 1' at the console?

V-Sync's broken on AMD card's

Hey!

I recently after long time tried gzdoom but the screen was heavily tearing. So I enabled VSYNC but it had no effect.
I was running Win10(64bit) and latest GPU drivers (AMD R7 360, Intel i7 3770k).
So opened the driver settings and added profile specificly to gzdoom.exe and forced VSYNC ON.
This had a sort-of effect as it loaded locked at 30 fps and it was painfully stuttering.
So it is either heavily tearing or stuttering resulting in awfull use.

My guess is that it is completly incompatible with AMD's FreeSync (Framerate synced with monitor) or AMD's improved V-sync (EnhancedSync, vsync without input-lag/stuttering) and thus suffering very badly.
I still have my CRT monitor lying around, but I would rather use my 4K monitor so ... letting u know ...
