Quoting julien.breval@tremplin-utc.net:
There is a HUGE speed difference depending if you use [pix_texture] or
[pix_draw]
that was the problem, sorry for this
by the way, thanks to the [pix_texture2] object, you can use any image size
Well, you still need an actual video card rather than that Intel chip to do much of anything useful in GEM. pix_texture2 is actually gone from GEM now, and in any case it doesn't really do arbitrary image sizes on Windows it just uses black pixels to fill in the rest of the power of two texture. It's very inefficient.
