Bug or Regression?

Bug

Description

Some games have massive stutters when in-game V-Sync is turned off and the frame rate is not the same as the monitor's refresh rate I have noticed this mainly on Hades or Quake 2 remaster As soon as I turn on V-Sync or limit the frame rate the games go back to running smoothly This maybe related to DXVK, since the stutters also go away when launching the game with PROTON_USE_WINED3D=1

How to reproduce

Play Hades with the frame rate above or bellow monitor's refresh rate

I don't think this is a hyprland issue. You can try enabling tearing, though.

lucascoelho07 commented 5 months ago

Works fine on Plasma Wayland and even Sway though I tested it with and without tearing on Hyprland too I've also used the default config to make sure it wasn't something on mine Is there any more info I can provide?

vaxerski commented 5 months ago

not much. It's likely some weird interaction in your configuration. I have doubts this is related to any de facto wrongdoing of hyprland.

lucascoelho07 commented 5 months ago

So, as someone who knows more about this stuff than me, could you kindly give me a light on how I could debug this? Like any logs I should check or places I could look out for worngness. Also, is it ok if I keep updating this report with new stuff I might find?

vaxerski commented 5 months ago

feel free. I don't have any pointers though, stutters are probably the app itself's fault and I don't know much about dxvk

Never seen such stuff either

I've tried running Hades on true Vulkan (not DXVK) and it solves the issue for that game, it used to crash when I tried to use Vulkan, don't know when or how it got fixed tho.
