Performance issues linked to backgrounds (of all things)

[AntonPetrochenko]

To preface this, I'm as confused by this as you may be.

So I've been having these bizarre FPS drops on 2024.906.2, and while troubleshooting them I isolated the cause to be regular old png backgrounds.

DxDiag.txt (osu running on the 1650, driver version 561.09)

Essentially:

• Certain maps have various degrees of FPS drops on my machine
• FPS drops appear to be somewhat tied to the resolution/file size of the background image
• Removing the background from an offending map solves the issue completely
  Additionally, setting background dim to 100% doesn't change anything (and bizarrely, causes a constant 50% performance drop on OpenGL renderer), only outright deleting the background image file works.

Sounds like hitting fill rate / draw call / gpu limits.

How would one go about troubleshooting this? Don't know the first thing about rendering but would love to help

A video with frame graphs up would help confirm this (Ctrl+F11 twice in game). You could also check your gpu usage in task manager while playing if you're on a newer windows version.
