I think the key word in Graeme's complaint is "game". And I'm willing to bet that most of his envisioned gaming scenarios deal with a lot of floating point math and the more advanced math functions. A quick glance over his example code and I'm willing to bet that the "math" unit providing the sqrt(), cos(), sin() and others is the bottle neck. But that's just a knee-jerk reaction. Seems to me I read a while back that a ton of effort had not gone into them.
Could those math routines just be written in assembly with a FastXXX unit? i.e. FastMM is a fast memory manager, so you could have a FastCRT, fastWhatever, FastMath...
At one time the fpc system units or sysutils was written in a lot of assembly, then they changed it to more pascal so it was more readable for people like me who stay away from assembly :-) Not because assembly is bad or anything, I just like living in high level procedural land, instead of low level assembly machine land.
