Summary

Introduction: Members of the RarelyTypicalPlayers community (a collective of developers and reviewers) came together in pursuit of optimizing the RMMV core scripts after finding some glaring issues in their code. The results show improvements of 10+ fps on average and have been made easy to use for even inexperienced users. An extra plugin was also created for those who need the stock behaviour, but still want improved performance. Parts of the core: The improved core is available in two forms:

Introduction:
Members of the RarelyTypicalPlayers community (a collective of developers and reviewers) came together in pursuit of optimizing the RMMV core scripts after finding some glaring issues in their code. The results show improvements of 10+ fps on average and have been made easy to use for even inexperienced users. An extra plugin was also created for those who need the stock behaviour, but still want improved performance.

Parts of the core:

The improved core is available in two forms:
  1. A plugin form: The plugin slipstreams all of the changes into one file. Helpful for clean-room patching.
  2. A patched set of scripts: This is the same as the core scripts, but with the changes included.
Depending on your needs, you can use either of these. If you are going with the second form, you can use the slim version of the plugin to tweak some extra areas of the engine.

Download:
You can grab both the plugin and/or the optimized core on itch.io or on Github (changes in the script are listed on the repo as well). The plugins are under the MIT license. The tuned core is in the same license as core scripts. Credit under AceOfAces.
