I haven't been around for awhile (too many other hobbies :), but I've
finally come back and upgraded with the liveCD to 8.04, and I quite like
what I see so far. Installation was a breeze, and everything is set up
nicely. Great work, guys!
I'm on a Sherline mill/lathe system with their driver box, and I'm reading
more thoroughly this time through, trying to get everything right finally. I
had lots of hardware issues back on Dapper that I'm hoping now to eliminate.
This time I reviewed the latency-test stuff until I better understood it.
I'm getting <10k(ns) when surfing the net, opening and moving around
windows, etc., but when I pop open glxgears, it leaps to ~150k+, and if I
maximize and minimize it, it skyrockets to over 300k. I've gotten maxes
right up to almost 400k while playing a somewhat processor heavy Flash game
online, so it would seem I'm in trouble.
The EMC2 manual sort of drops me at that point, and moves on to other
things. Could my GeForce4 Ti 4600 simply be too underpowered? This older
Shuttle is a bit laggy opening windows and maximizing and such, as compared
to the new system I built late last year with a hot new card, which never
slows down for anything. I have run '$ metacity --replace' to make sure I'm
not using Compiz to see if that would help (nope). I've also watched the
system resources in the monitor, and the CPU is always at 100% when I'm in
the latency test - is this expected, or is it not supposed to be maxing my
system out?
Also, the manual seems to imply that there might be something other than
software stepping. Is there hardware stepping? The wording in there is of a
"your computer might not be good enough for software stepping" nature, and I
got the impression that maybe that meant that there was an altnerative that
the manual forgot to come back and talk about. No?
The computer and graphics card were new 6-7 years ago, so they're a bit
older now, but I'm hoping that they're still usable. I'm thinking the
terrible latencies might have been the root of other problems I experienced
back on the Dapper build.
Thanks!
