Dear Greg,<br>After installing nvidia graphics drivers, i am not able to open chimera. I have attached the xconfig file and the output of glxinfo as text files.<br><br><b>[cbala@ramana ~]$ chimera<br>Traceback (most recent call last):<br>

Looking at your chimera benchmark scores and at the scores on the web page, <a href="http://socrates2.cgl.ucsf.edu/trac/chimera/wiki/benchmarks" target="_blank">http://socrates2.cgl.ucsf.edu/trac/chimera/wiki/benchmarks</a>, it looks like you don't have the NVidia graphics driver installed. And that would make a *huge* difference. To double-check, run the glxinfo command and look at the "OpenGL renderer string:" line, it should have NVIDIA in it instead of Mesa. To get the NVidia drivers, go to <<a href="http://www.nvidia.com/Download/index.aspx" target="_blank">http://www.nvidia.com/Download/index.aspx</a>>.<br>

Dear Greg,<br>
You are right. Previously it was normal but now it is slow. I havent updated<br>
the kernel. I checked and noticed that i dnt have any memory intensive<br>
background jobs also.<br>
<br>
I did benchmarks with two chimera versions 1.3 (attached file chim_test) and<br>
chimera 1.4 (attached chim_test1).<br>
My graphics card is nVIDIA GETFORCE 9300MG, VRAM: 256 MB. I dnt know how to<br>
compare and judge what is going wrong. I wud appreciate your help on the<br>
same.<br>
<br>
Thanks,<br>
Bala<br>

So it was formerly fast on the same computer? This could happen on a Linux<br>

computer if you updated the kernel and forgot to reinstall the graphics<br>
driver (from ATI or NVidia, the open source 3D drivers still need work, but<br>
are improving). Another possibility, on all operatings sytems, is that<br>
there is a background process that is using a lot of CPU or memory, so<br>
chimera doesn't have the resources it used to.<br>
<br>
If you just want to check the graphics performance, then you can use the<br>
Benchmark tool in Tool / Utilities to guage the current performance. And<br>
then you can compare to the reported scores to see if your graphics<br>
performance is reasonable (the Show button in the Benchmark tool brings up<br>
the web page).<br>
