Platform Builder is great for making good games, but it lacks of performance most of the times.
Only with a small advanced system, the games lags a lot. I have a looping timeline that lags a lot, it loops each 6 GM steps (0:0.2) and has no very much code.
So, yes, Platform Builder actually needs a performance update as soon as possible.
I saw some other programs and games that in 1 version improved the performance x1000 or something like that. Might this be possible with PB?
