So, Reborn is a very well polished game, but I'm sure we've all noticed that some areas have some cripplingly bad lag in certain areas, especially on older computers. I've taken it on to try and identify some of the biggest offenders and attempt to fix them. Before that, I managed to obtain permission from Ame to do it (I felt really uncomfortable even thinking about doing so otherwise), and as a result, I've already managed to neutralize the lag on Route 2 and Obsidia Ward. The results of my efforts will be at the bottom of the post.
Either way, I started this topic to try and drum up some responses: What areas would you all say have some really bad lag, also if possible what are the specs of the computer you used to play Reborn on? I wanna try and look into the maps and see if optimization is possible for them. I've accumulated a short list of areas I know that have some funky lag; I'm sure the list is incomplete, but here's what I have so far.
Route 2 (Divide the map into two - Fixed)
Obsidia Ward (Create a secondary map for after PULSE Tangrowth - Fixed)
Chysolia Forest (Secondary map for after PULSE Abra)
Spinel Town (Same as Chrysolia)
Jasper Ward (The only possible way to fix this would be for a map after PULSE Tangrowth)
Beryl Ward (Same as Jasper)
I've seen some people mention Peridot Ward, but I can't confirm it as it doesn't really lag for me.
Additional maps I'll be looking at on people's request:
Route 1 (When it rains, might just be an issue with weather)
Byxbysion Wasteland (I... don't think this can be fixed. Byxbysion is just too large and has too many events to properly handle any other way)
Apophyll Beach (Near Academy entrance)
Ametrine City (Might divide Ametrine City and Ametrine Mountain Peak into two different maps, divided by player transfer commands at the first set of stairs leading up the mountain)
All that really needs to be mentioned is on what map the lag occurs, if it's in a specific area of the map (A screenshot would be helpful here), and the specs of your computer if you can get them. Knowing these three things will make it possible to deduce if the lag is a severe problem, or just an issue of a weaker machine being unable to handle the engine pushing that Pokemon Essentials does to even work in RPG Maker (Which is the main reason for the lag through and through, RPG Maker as a whole is an old engine and Essentials pushes it to and beyond its limits). I also apologize if this is in the wrong area, and request that it be moved if it is.
Below this is my fixes for Route 2 and Obsidia Ward, where I'll explain what the initial problem was and how I went about fixing it.
