Description

I'm playing on Switch and I recently updated from 1.7.8 to 1.9.0 and then 1.9.2 latest.

  • Launching RetroArch now takes 80 seconds!
  • Launching content (I'm playing Beetle VB right now) also takes takes 80 seconds

I've removed all cores I won't use, a trick needed on 3DS, but there has been no speed up.

What is the cause of this slowness?

I plan to downgrade my RetroArch back to a version before this and I'll report back.

Switch 10.2
CFW AMS 0.15.0

Research direction

No source file or test is identified. Reproduce the launch and content-loading delays on Switch 10.2 with CFW AMS 0.15.0 across versions 1.7.8, 1.9.0, and 1.9.2, then compare the results to identify the regression and verify that startup times improve.
