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.
