Ah, yes thank you, schoolboy's error.
Sooo... the specs are
Win XP SP 2
Via AC97 integrated audio on a KT8233 Southbridge (K8T800 Mainboard), driver is the current one as of today (28.04.2008)
The problem is new in the sense that I have had freelancer running fine previously on the machine. I haven't had it installed for a while, then installed it and immediately put crossfire 1.70 over a pristine, vanilla installation using FLMM 1.3
Further specs (for ref. only)
Athlon 64 3000+
512 MB Ram
64 MB ATi Radeon 9600
Thanks for the quick reply. Any other info that's needed lemme know.
