Linux wayland nvidia - high cpu usage when starting game #13623

Open andrewfader opened 2 years ago

andrewfader commented 2 years ago

So I have it recognizing vk_wayland but when I load a game I have high cpu usage like it's not using the gpu for vulkan rendering. Using the bsnes hd core.

Can you give us some feedback about high cpu usage with something like

while true; do echo -n "RetroArch ";ps -p `pidof retroarch` -o %cpu,%mem ; sleep 5; done

or

watch ps -p `pidof retroarch` -o %cpu,%mem

Thank you.

@andrewfader Is still an issue with latest stable ? Thank you.

andrew-fader-discovery commented 3 months ago

Yes, it's still reproducible with bsnes-hd beta core, but if I switch to bsnes-mercury performance, the cpu usage is acceptable (100% of one core and 10% of a 2nd) as opposed to pegging all those cores.

gouchi commented 3 months ago

Which package are you using distro ? Flatpak ? Snap ? AppImage ? May you provide full log ?

Thank you for your test.
