[FTEQW] G-Sync causes unexpected behavior #48

Closed DerpedCrusader closed 1 year ago

DerpedCrusader commented 2 years ago

Describe the bug when starting the game with G-Sync enabled, some weird stuff occurs, like gl_blendsprites being turned off, and weird frame interpolation

the interpolation errors only happen when above 60hz

To Reproduce Steps to reproduce the behavior:

  1. turn on G-sync
  2. run the game

Expected behavior

you'd expect it to be like any other frame rate cap or limiter, where it caps it around the refreshrate (which it does at 60hz)

and to leave certain commands uneffected

Screenshots/Footage in this footage, the application on the right was started up without G-Sync enabled, and the one on the left was started with G-Sync enabled, as indicated by the icon in the top right corner of the application

the only command i entered was show_fps to make give proof to everything working properly

Affected Platforms:

Additional context I don't know if this is something than can be fixed, I'd say for the time being, try to find a way to disable G-Sync specifically for NZP, and it should run smooth as butter

Can you take another video with G-Sync enabled and show_fps set to 2? Is this problem alleviated when fullscreen is enabled? This may be an nVidia issue ultimately, according to Spike.

DerpedCrusader commented 2 years ago

It is alleviated when fullscreen is enabled

heres what it looks like with show_fps 2

Going to close this as it's better suited being posted on the FTE repo: https://github.com/fte-team/fteqw. You can probably use the same footage and most of the same details there and get an actual fix.
