Lag then pressing any key on the keyboard

[Hiro420]

Lately, there is a bug in which every time I press any key (to click the circles), there is a small lag, and when I play steam maps it becomes unplayable. Also, it doesnt affect the fps counter at all. It's 100% sure not hardware issue since I'm using a good PC with RTX 3060TI

Also, its important to say, it happens only when playing a map, not in the menu

Hit CTRL + F11 and check which color bar is the highest. This is very likely a software problem on your end, meaning the game can't do anything about it, so you have to fix it yourself.

this happens

this happens

Those big yellow lines mean that some other program running on your computer is freezing the game every time you press a key. It's your job now to figure out which program is interfering.

but i also saw that when i press any key, mcosu instantly takes 100% of gpu power

additionally, i restarted my pc and closed all processes but the windows ones, the bug still happens but only when i click when playing maps. it doesnt happen when its autoplay or when im clicking in song selection menu

[McKay42]

Close ALL other programs (Discord, Chrome, Skype, Teams, TeamSpeak, Firefox, Wallpaper Engine, Steam, MSI Afterburner, RivaTuner/RTSS, Corsair iCUE, Razer Chroma, GeForce Experience Overlay, etc.) and directly run McEngine.exe from /\<Steam>/steamapps/common/McOsu/. The game can't do anything about random crap running on your system in the background, especially stuff like overlays which inject themselves into the game process and cause random bugs like that.

Let's try this:

• Delete all files in /\<Steam>/steamapps/common/McOsu/cfg/
• Steam > Library > right click on McOsu > Properties > Local files > "Verify integrity of game files"
• Only configure your osu!folder and nothing else

See if that changes anything.

doesnt help

the lag is because 100% gpu usage

Reinstall Windows or something, seems like your setup is broken. As this doesn't happen on any other machine besides yours, it is 100% something caused by a 3rd party application you have installed and/or running.
