@walkerb Just for completeness, flicker-free graphics on the #C64 aren't achieved *only* by drawing speed. Like on any platform where you update some "framebuffer" that's used live by the gfx chip, even the fastest drawing routine will show flickering when executed at the "wrong" raster beam position.

So, you also have to care about #vsync (or: "race the beam"): only start drawing some area after the raster beam passed it.

Un petit article technique, parce qu'il va falloir arrêter une bonne fois pour toutes d'utiliser SDL_Delay()…

V-Sync, off or on?

it looks like xorg||cinnamon and vsync are not very friendly to multi orientation displays. Disgaea 2 (linux native) keeps flickering while in full screen mode
inxi -G
loaded: amdgpu unloaded: modesetting dri: radeonsi gpu: amdgpu resolution:
1: 1080x1920~60Hz 2: 1920x1080~60Hz

Solution: running the game in nested x server with xephyr
the weeb inside me is very happy rn

@enron I do daily drive #sway too, is amazing that no extra configuration needed in it. But some stuff made me stick to #X11, for which I'm wondering about comps.
I've already tried #picom #vsync solution, but it has very poor performance & stutter everywhere...

What's the most minimal #X11 #compositor to pair with #i3 ?
I just need two features

Nothing else. Just above two features.

I'm gearing towards #picom, but searching for more minimal & without #python dependencies.

No animation / anti aliasing stuff needed. Just above two features.

I've been fighting against tearing from an Intel HD Graphics 620 iGPU, on #Linux with #Xorg. After trying recommended options like TearFree and TripleBuffer, intel and modesetting drivers, even #Xcompmgr, nothing would solve it. #Wayland, on the other hand, works tearfree out of the box. Finally, I tried #Picom on X, a fork of a fork of a fork of Xcompmgr, and it worked! Its #vsync option, enabled by default, does the trick.

is there a #Wayland fork that disables the #vsync or something

I heard games can do it in their settings already

hey mastodon
does anyone know how to disable #vsync for an #opengl render frame ? I'm trying to do a #VR #game engine but I get capped to 60fps :/
