Hi Chris,
I'm trying to do some google searching on how to debug the nvidia binary driver, but looks like (perhaps) only nvidia can do that...
Anyhow attached is the oprofile with the function calls, which does not tell me about anything in Gem I did not already know, and the two biggest calls, for rubber and the colour conversion, add up to 14%. 50% is sucked up by the black box of libGLCore.
The newer nvidia driver I installed yesterday does help, it takes longer for the CPU to get up to 100%, but certainly not not fix the problem.
If anyone knows: A: how to get more info about what the hell libGLcore is doing B: what the heck "zero" is and why its using 12% CPU
If I can't get anywhere on this today I guess I'll have to keep rebooting the machine each 2hrs or so, I will be baby sitting it anyhow, and it is only 2 days, but the next installation is going to be 3 days starting May 23rd.
Thanks, .b.

I think you need a better profiler which traces the calls. Just listing the libs is only marginally more useful than top. There's nothing to indicate if the driver is spending time uploading textures or vertices or just waiting for the GPU or doing something stupid. Without that info there is little anyone can do to fix any problems.

Hey all,
So I'm going to leave the patch on overnight and *HOPE* that it does not due the weird spike while I'm gone.
Right now this is what the profile looks like:
5028091 51.5756 libGLcore.so.1.0.8756 2287523 23.4643 Gem.pd_linux 1155076 11.8482 zero 402984 4.1336 pd 336232 3.4489 libfreetype.so.6.3.5 210094 2.1550 libc-2.3.6.so 179207 1.8382 libm-2.3.6.so 75334 0.7727 libGL.so.1.0.8756 63900 0.6555 libX11.so.6.2 4586 0.0470 libpthread-2.3.6.so 3691 0.0379 libGLU.so.1.3 1618 0.0166 comport.pd_linux 199 0.0020 expr.pd_linux 182 0.0019 libpython2.3.so.1.0 78 8.0e-04 zexy.pd_linux 72 7.4e-04 libstdc++.so.6.0.8 46 4.7e-04 py.pd_linux 30 3.1e-04 xsample.pd_linux 17 1.7e-04 pool.pd_linux 11 1.1e-04 prepend.pd_linuxSo the question is, what the heck is "zero" and why is pd linked with it???
I really hope this newer binary fixes the issue.
Thanks all for your help.
