Re: [fpc-pascal] GLM library alternative?

I've done a bit of assembly programming for IA-32, none recently and zero compiler development other than simple parsers, but from what I know optimizing with newer instructions like SSEx is only part of there story. There's also optimizing for out of order instruction execution (OoOIE), or

tested with the fpc trunk , got only 3 fps increased . but even with this result fpc does great job , compared with gcc7 , gcc is faster only about 45% . so when compared with a compiler like gcc which get tens of patches par day from from around the world including big companies like sumsung .

Marco, Regarding 2D animation, what I've far far more effective than an orthographic projection is to draw 2D billboard sprite at a distance and size to align exactly with your screen's resolution. That is each width and height of "1" gl world equals "1" screen pixel, and coordinate (0, 0) equals
