well...I don't know, but other games work fine. Even ut2004 runs on a good speed(which uses linux emulation aswell). FreeBSD's kernel has its own AGP stuff(like linux), when I start X I see a message that nvidia doesn't use its own AGP code because FreeBSD's one is active.
sysctl doesn't know any 'machdep.allowaperture', so I'm not sure if it exists for fbsd.
Thanks anyway
I'll try it when I'm on linux, game looks good
