Slow fps, even when game is reporting reasonable fps

seth · 2025-05-19 22:27:20

Libreoffice: https://bugs.documentfoundation.org/sho … ?id=152911
Try to actually run picom (o the glx backend)

running "picom" in the terminal makes a smooth transition when i switch workspaces, but does not fix the tearing
ok... so libre office slow is just a bug?

do you think this could be a bug in the game? i am running an older-than-required graphics card, so maybe "bug" is a bit harsh.

LO is OTR for this kind of ridiculous inefficiency, yes.
If you're looking for a lightweight, MSO-compatible office suite, have a look at https://aur.archlinux.org/packages/freeoffice (as in beer, not freedom)

As for tearing: do you still export __GL_SYNC_TO_VBLANK somewhere?

echo $__GL_SYNC_TO_VBLANK

Does glxgears show any tearing?

neither option fixes tearing in firefox

nb. that firefox will by default not spawn a new process but attach to the current one, you've to make sure to "killall firefox" before starting it w/ different environment paramters.

Does "__GL_SYNC_TO_VBLANK=1" tear???
(w/o picom running)

i think the errors show up after i view the screen tearing video on youtube, but the tearing is visible just viewing this page.

i think i'm going to submit a bug to the game, since it has been slow a lot. I'm not sure why it got better for a while when i first deleted those config files.

Do you btw. set "gfx.webrender.compositor.force-enabled" in about:config in firefox?
Afaict it should default to software rendering?

i ordered a used rx 470.

Now I get higher fps, but I still get stuttering (i don't know if this is the same thing that was happening before or not. maybe the reason the game originally reported a higher fps, but i saw visually a much lower fps, is because there was stuttering mixed in?). I am now using mangohud, and find that while i can get 115fps with this new card, I also get a 60ms stutter frame every 2.8 seconds like clockwork. on 0ad i get a similar stutter but it's smaller and faster (every 0.3 seconds)

Edit: i do not get the "clockwork stutter" on furmark or heaven

Edit: Libre office is still atrociously slow. arch wiki for amd fixed tearing with this new gpu. I just tried the xrandr temporary solution. I haven't tried getting it permanent or telling for sure if it affects game performance.

sidenote: any suggestions on how to verify there's nothing wrong with the new (used) card?

thanks

Run a stress test, if if melts, there was something wrong with it

For the games,

export vblank_mode=0

(Or, if we're leaving 0ad aside, "mangohud" implies steam?)
For libreoffice, you already figured that it causes severe cpu load - if this is regardless of hardware acceleration being enabled, this is simply due its inefficient code and no GPU in the world will fix some CPU hog.

Arch Linux
