I have openchrome drivers installed for my CN700 Unichrome Pro graphics card (
http://www.via.com.tw/en/products/chipsets/c-series/cn700/ ) . It increased the
glxgears output from 180fps with vesa to around 600fps but has not allowed me
to access the opengl pipeline.
Here is the output of java -Dsun.java2d.opengl=True -jar SwingSet2.jar

Could you tell me whether this card could be suitable. From reading the specs I
really thought It would be sufficient.
There is also a driver produced by via. The linux community hsa reported much
better success with the openchrome driver however. Could using the VIA driver
have a different result?
Thanks in advance.
