[Support] Picom goes really slowly.

Drogobo · 2022-11-16 13:35:45

I am on default everything, and when I run picom, it makes my refresh rate like 30. I am using vsync and all, and xrender for rendering. I am on nvidia 2070 super. I ran picom from a terminal, and it didn’t output… ANYTHING. So do I need to wait for some magical update? I haven’t touched my picom.conf in like 2 months, so it has to be that some part broke.

Xrender is very slow and does afaik not really support vsync in the first place. You should be using the GLX backend in the majority of cases.

xrender should™ perform pretty good on the proprietary nvidia driver
Post your picom.conf and the output of "glxgears", "glxinfo -B" and "xrandr -q" and your xorg log, https://wiki.archlinux.org/title/Xorg#General

Please use "code" tags, https://bbs.archlinux.org/help.php#bbcode
There's just one output, at 240Hz and glxgears runs at 240fps - likely because you're using vsync in picom.conf (you didn't post that) through an auxiliary GL context.
It's not an optimus system and regardless of the pointless /etc/X11/xorg.conf created by nvidia-settings, you're running on the nvidia driver.

Nothing here remotely suggests that "it makes my refresh rate like 30" - you might want to elaborate on that.
What exactly is your testcase and metric for this?

I don't have a metric. I am eyeballing it. But it still looks really choppy with picom, and when I kill picom, it goes away.

What exactly looks choppy? glxgears as well?

GLX gears is fine, but I use xrender on picom.

glxgeas still passes through picom.

your picom.conf wrote:

# vsync = false
vsync = true;

Does this value have any impact on the situation?

When I use xrender it does. Disabling vsync with xrender made it even slower.

What does that actually mean?
What *is* your test case? Moving windows, playing videos, …?

In my experience, depending on the hardware, picom is just that slow. That's why I hacked an early compton version, you may want to try it (;
