Try getting the call stack for Gem.&nbsp; This should trace the GL driver function back to the Gem call that triggered it.&nbsp; Following Tim's link above try opreport -cl --demangle=smart<br><br>Having something that does more that dump a billion lines of text to the console will help immensely in sorting out the profile.&nbsp;

Hi Chris,<br><br>I'm trying to do some google searching on how to debug the nvidia binary<br>driver, but looks like (perhaps) only nvidia can do that...<br><br>Anyhow attached is the oprofile with the function calls, which does not
<br>tell me about anything in Gem I did not already know, and the two biggest<br>calls, for rubber and the colour conversion, add up to 14%. 50% is sucked<br>up by the black box of libGLCore.<br><br>The newer nvidia driver I installed yesterday does help, it takes longer
<br>for the CPU to get up to 100%, but certainly not not fix the problem.<br><br>If anyone knows:<br>A: how to get more info about what the hell libGLcore is doing<br>B: what the heck &quot;zero&quot; is and why its using 12% CPU
<br><br>If I can't get anywhere on this today I guess I'll have to keep rebooting<br>the machine each 2hrs or so, I will be baby sitting it anyhow, and it is<br>only 2 days, but the next installation is going to be 3 days starting May
<br>23rd.<br><br>Thanks,<br>.b.<br><br>n Tue, May 16, 2006 6:52 pm, chris clepper said:<br>&gt; I think you need a better profiler which traces the calls.&nbsp;&nbsp;Just listing<br>&gt; the<br>&gt; libs is only marginally more useful than top.&nbsp;&nbsp;There's nothing to indicate
<br>&gt; if the driver is spending time uploading textures or vertices or just<br>&gt; waiting for the GPU or doing something stupid. Without that info there is<br>&gt; little anyone can do to fix any problems.<br>&gt;<br>
