Are you using the open source nouveau driver? If so, that would
explain the abysmal performance. The proprietary NVIDIA driver is
much faster.<br>

<div>Hello:</div>
<div><br>
</div>
<div>I was wondering if anyone had any experience tracking down
performance problems in chimera.</div>
<div><br>
</div>
<div>I've noticed that I am getting really sluggish performance
when managing a lot of atoms, even when everything is shown as
backbone traces only.</div>
<div><br>
</div>
<div>To take a look at the performance, I ran the benchmark and
got the following numbers:</div>
<div><br>
</div>
<div>Volume benchmark scores</div>
<div> surface mesh contour solid recolor</div>
<div> 981 1291 280 589 393</div>

<div><br>
</div>
<div><br>
</div>
<div>compared to a benchmark posted on the website of the same
graphics card:</div>
<div><br>
</div>
<div>2125 2026 302 512 491</div>
<div><br>
</div>
<div>213 492 452 3259 169 128</div>
<div><br>
</div>
<div>Apparently I'm getting awful benchmarks for most of the
molecule benchmarks, while the volume performance is pretty
comparable. I re-ran the molecule benchmarks to make sure they
were reproducible and got pretty much the same numbers.</div>
<div><br>
</div>
<div>Would anybody have any suggestions for figuring out what's
going on?</div>
<div><br>
</div>
<div>For reference, I'm running ubuntu 12.04 with up to date
nvidia drivers for a GTX 560 Ti.</div>
<div><br>
</div>
<div>Thanks,</div>
