Re: [osg-users] Has anyone tried 64-bit SUSE enterprise
Hi Brede, The slow down in performance could be down to either the OSG or OpenGL. When stats is enabled the OSG, on hardware that supports it, will put timing tokens into the OpenGL fifo to collect GPU stats - this is used in the orange GPU text and bars. The OSG' collection of stats itself isn't multi-threaded, except when you have multiple graphics windows active, and the granulatity of the threading is simply the same as normal rendering. The enabling of multi-core might be leading to the OSG using DrawThreadPerContext rather than SingleThreaded on you machine, so this could be a potention change. Try forcing SingleThreaded then try the stats. I don't think this will make any difference but it would at least tick on possibility off the list. My best guess right now is that this bug is an NVidia driver bug in collecting GPU stats + running with running dual core. Robert. On 8/20/07, Brede Johansen [EMAIL PROTECTED] wrote: Robert, Yes the continuous drop in framerate only happens when the bar graph stats are active. The help screen doesn't have this problem. One interesting thing is that when I remove the stats the framerate is back to normal and when the stats are enabled again the drop continues from where it was last time stats where active! I found out that disabling one of the two cores in the BIOS settings I was no longer able to reproduce the drop in framerate. I do have some problems with BSOD when running OSG applications with both cores enabled so it might be an indication of a driver issue.

I think it might be related to 64-bit build on SUSE. I don't have much more details than this. Commenting out any of the setText code allows my application to run fine. You might want to try and get a stack trace with gdb. If it turns out that you have vector iterators or OpenThreads in the stack trace, then it's probably a question of calling setText() while another thread is running the draw traversal. To be safe with all threading models that OSG supports, setText on an osgText object must be called in the update traversal. I've run into this lately myself, and the tricky part is that it won't necessarily crash each time you call setText(), it depends on timing issues. Using an update callback fixed it for me. I just have a setText() method in my callback class which saves the new text but does not set it just yet. I then attach an instance of the callback class to the osgText object, and in the callback's operator() method I call setText on the osgText object (gotten from casting the drawable given to operator()). This guarantees that the actual osgText::setText() call will be done in the update traversal, and seems to work great for me on Windows and Linux. If you need a more concrete code example just ask, but it's pretty simple. Then again I may be completely off track here. In any case, getting a stack trace is the first thing to do in order to diagnose the problem correctly.

I am still poking around but do not know if I can resolve this quickly. Strange - I was running a 64bit Mandriva and it was working for me just fine. Do you happen to have an ATI card? They seem to not like osgText too much.

Re: [osg-users] Has anyone tried 64-bit SUSE enterprise
Hello Jan: Thank you for the insight on your experiences. Yes the stats in osgviewer produces the same problem and causes core dumps. If the osg example apps are static text where theyare set at load time and never change like in osgtext example then no crash, but is really slow to render. I think you are right that it's a ATI problem more than likely the drivers for SUSE. The MAC drivers work great.

If it turns out that you have vector iterators or OpenThreads in the stack trace, then it's probably a question of calling setText() while another thread is running the draw traversal. :). Wish I could. The setText is completly hosing everything. I have tried the gdb on the executable. I usually have to reboot. Reboot?? Whoa, now that is really a bad issue. Do you have problems displaying the stats in the osgviewer as well?

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, Garrett Potts wrote: hello Jan: Hmmm, funny you mention it. The SUSE enterprise is running on Mac Hardware and so yes it is an ATI board. I also have tried te osgtext example. It runs but is very slow. I do get the same crash issues with osgviewer stats hud where the text is changing on every frame which simulates what I am doing. It could be a driver issue. The MAC OSX handles it very well and I don't remember having any problems on the windows on the MAC running the bootcamp ATI drivers. It is a long standing bad driver/OSG interaction. I have the same issue on my laptop with a FireGL T2 card and i586 since at least two years, likely longer. If there is any osgText in the scene, the viewer locks up in a busy loop, pegging the CPU at 100% load. Usually it wakes up after several minutes, though, without a reboot. I believe that it has to do with the way osgText is implemented - by rendering glyphs into many small textures which need to be generated and uploaded to the GPU when the node is first time rendered. The subsequent triggering of stats or help is immediate for me, only the first one is always a problem. I have solved this issue by implementing my own text widget using Cairo and Freetype. That way I have only a single quad with a single texture, regardless of how many characters and with what font I render.
