At Phoronix we are constantly exploring the different display 
drivers under Linux, and while we have reviewed Sun's Check Tool and 
test motherboards with Solaris in addition to covering a few other 
areas, we have yet to perform a graphics driver comparison between Linux 
and Solaris. That is until today. With interest in Solaris on the rise 
thanks to Project Indiana, we have decided to finally offer our first 
quantitative graphics comparison between Linux and Solaris with the 
NVIDIA proprietary drivers.
