I have a cust developing on 4TRAM High Impact, loads about 3.5MB of
texture down using Guy Russell's enahnced pfuTexDownload, which reports
about 3.5MB texture in use (but about 522 tex pages ?), but gets
constant texture thrashing (as reported in pfStats). By experiment he
has found that if texture in model is reduced to 1 MB (as reported by
pfuDownLoad) thrashing stops. All tools seem to be reporting the
right thing:
 - gfxinfo says 4 TRAM
 - pfuDownLoad says ~ 1MB or 3.5MB
 - Multigen agrees about amount of texture in model.
 - Multigen is using default texture modes.
 - Ditto Perfoemer, so I asume we're getting 16-bit texels.
                   
The 1MB limit is v. suspicious, is there any way for some part of the
system to get it wrong and thinkj it only has 1MB TRAM ?
