Hi Eric,
As an addendum to my earlier posts about this problem, I just experienced
the frame stutter problem for the first time!!
I have been having a major problem with my nightly backup since installing
the Thriller3D card. I have been using the task scheduler to run an
automated backup for years and the process locks-up sometimes--freezing my
computer. It only happens with the Thriller3D, and now I have discovered a
new clue. It seems to only have a problem if I have run GPL (1.1) (the only
program I use that uses the Rendition acceleration of the Thriller)
beforehand (in the current boot).
A friend suggested that I try running a small app., like the clock or
something, a minute or two ahead of the scheduled backup to see if that
might wake up the computer or the Thriller a little more thoroughly. When I
tried to add a new item to the scheduler (the clock), the computer prompted
me for my Office2000 CD!?!?!?! I wondered what was happening until I
realised that O2000 was updating the task scheduler itself. I had done a
custom install of O2000 and I guess I did not select whatever updates the
scheduler. Then, I thought, great! Maybe my lock-ups won't occur anymore
as the scheduler itself has been updated. (We'll find out tonight.)
After a reboot, I started GPL and the frame stuttering problem was
immediately apparent. Very problematic and ruined the game. There was also
a definite appearance of some of the slo mo effect I get consistently with
the Voodoo2 card. I switched back to 3dfx, and the slo mo seemed to be even
worse than before. Switched back to Rendition, and back to stuttering. I
exited GPL and turned off (paused) the task scheduler--stuttering gone.
Exit again and switch the scheduler on--back to stuttering in GPL.
After a few more reboots and playing around with the scheduler, I have
managed to get back to where I was--no stuttering in either version and slo
mo in 3dfx only. Hopefully, my automatic backup lock-up will be helped by
the new scheduler files, but it sure taught me that the scheduler can have a
major effect on the smoothness and operation of GPL.
