I am running an athlon 64 x2 4600+,2gig ram,hd4850 1gig on 10.6catalyst (tried 10.10 but in this building it crashed the card so hard it rebooted the pc) and xp pro sp3. Every building i have so far been into is fine apart from ranger station golf main building, not the tents. After anything from 10 secs to a few mins i get a whole mess of corrupt textures/polygons forcing vpu recover to try and save the situation, but in the end have to ctrl-alt-del to kill fallout in task manager, or occasionally hard reboot the pc. Is anyone else getting this in this building? Just keeping fingers crossed the strip is not like this or my adventures end here.
