Wasn't the texture repeat bug that Patch 154 addresses attributed
to RE microcode? The historical mailing list traffic to which you
allude stated that the patch made IRIX 5.3 consistent with earlier
OS versions in working around the problem, but that performance
was still degraded with textures cycling more than 15 times.
No one, to my recollection, ever advanced a quantitative estimate
of the negative impact on fill performance.
What negative side effects did you observe with the patch? We
have installed it on a number of deskside Onyxes, and one rackmount,
and haven't noticed any new problems as a result. The texture
repeat bug was cured, but alas I am not in the position to comment
on the degree to which fill speed was affected.
Regards,
Jean Daigle.
