@AdamSakuru Yes, I still have it on my TO-DO list. I was planning to make it so you can set a default color setup, you can setup an override on every map and you can change it dynamically on maps as you please. This would help people that change the map over time, e.g. a day-and-night system that needs to adapt the color.

@BreakerZero If it's any consolation, driver updates often fix these issues. I played FFXV about half a year ago on my GTX 1060 laptop and it also had some weird issues which went away after I updated the driver on some point. My suggestion is (from professional experience) that you test the final build on the worst PC hardware configuration you can possibly find, preferably one that runs an integrated GPU and a weak CPU in general. Well, the actual best practice would be to test it on as many configurations as possible, but testing it just on a potato PC can be enough.
Oh BTW, I just remembered something that you should definitely check out. Back in the RMXP days some people would experience ridiculous performance issues for no apparent reason. Input would be dropped, lag would occur inconsistently, etc. Turns out their anti-virus was going haywire for some reason. Might be worth a try to disable your AV just to see if you have any positive results.
Other than that I suggest you just run the integrated profiler. It really helped me pinpoint the performance issues in UM7 which is actually how I found the memory leak bug in the default scripts.
