Another test would be to disable the random ground cover objects. How does this impact tile paging performance? FWIW, I've been running on a 256Mb Linux machine with a GeForce2 MX (32Mb) just fine for a year or two. My system is scsi based though so with threaded tile paging, that will definitely make a performance difference. However, it seems that the biggest hit when paging tiles is in freeing memory for tiles that are purged from the cache.
