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