ParticleDemo is much faster under Linux than Windows

[joen]

Hi everyone, I have a question about the ParticleDemo performance.

I compared the performance between linux and windows.

Under the Ubuntu 12.04, the total time of particleDemo using GPU is about 1~2ms,
but the time under windows is about 15ms. Moreover, I checked the driver and the driver is up-to-date.

What reason does the program make the difference between Linux and Windows?

Linux with recent drivers is faster then Windows.

Windows has extensive DRM and Linux does not. So Linux would be always faster if drivers have similar performance.
