when using v119 simply open setup.ini/buildgame.ini and change memcapoff=0 to =1.
it doesnt run on xp because xp is 32bit-concept, while vista and win7 are 64bit-projects that are simply downgraded to 32bit, so it seems the needed software-components to run fpsc with higher cap are still there, but watch out, even in win7 and vista fpsc uses virtual memory for everything over 1.85gb in 32bit-version, so it depends on your harddrive how good/bad it will work. i wouldnt change to bigger cap simply because most people/gamers overall still work with xp-32bit. you will loose all your customer-base and risk problems in the finalbuild.

fpsc
IS the engine, there is no other thing behind, darkbasic is the language (wich is the first problem as far as i know^^). v120 is in work and will be a power-update only, so stay in and watch for its betas. but dont expect to get a cry-engine, not possible with that much automatism and stock fpsc offers to all us coder-noobs.
