Description

Game Name?

Skies of Arcadia Legends - GEAE8P

What's the problem? Describe what went wrong.

4.0-9200 (https://github.com/dolphin-emu/dolphin/pull/3752) introduced a huuuuuuge performance regression when entering battles. The screen shatter slows it down to 4 FPS.

What steps will reproduce the problem?

Get into a random battle. This can require playing through some story or I'll attach a save or something.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

4.0-9410, 4.0-9198, 4.0-9200

What are your PC specifications? (CPU, GPU, Operating System, more)

Core i5-3570K, GTX 760, Windows 10

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

So, this relates to a performance optimization that was not done in PR 3752, as none of the games which were tested showed any major performance regression. We always planned to get to it after 5.0

We can't simply revert 3752 as that would break other games. It would be possible to conditionally revert it based on an ini file option just for the 5.0 release, but that's an ugly hack.

I'm going to make an attempt at a PR which fixes the performance optimization in a way that doesn't cause any other regressions. If that PR doesn't work out, we might be better leaving this as a known performance regression for the 5.0 release.
