The real reasons of M:PN1 lagging were many complex vector graphics displayed on the screen at once (weapons, enemies, lockers, doors) and I also suspect bad coding practices combined with the use of ActionScript 2.0 and Flash Player version 8, which are notoriously slow and known for not optimising graphical performance.

Looked on the blog, I guess it must have been the shading effect or something, but I thought the GO3LM looked really unfinished since the front of it look missing. Sorry for the mix up.
