Seems like texture dimensions are the problem. Some of you have an older version of OpenGL(1.1 or so) so it doesn't support textures ! power of 2. Maybe that's also causing the slowdown on certain computers [smile].
Final testing on my mums computer later today, then I will upload(this fucking school won't let me create/upload .zip files anyway HAXXOR).
Yep, worked for me too. Still kinda fast though, but I don't know how fast it's supposed to be (and since it's a work in progress that's probably not the most important thing ever).
