Post FluidMark 1.2.2: compiled with newest PhysX SDK 2.8.4.

Jerome 'JeGX' Guinot has updated his popular benchmarking tool, known as PhysX FluidMark, to version 1.2.2.

Release Notes:
Version 1.2.2 ' 2010-09-20
! Change: new post processing (post-FX) effect.
! Change: scores submissions are limited to fullscreen mode + No AA + No PostFX.
! Update: compiled with PhysX SDK
* Bugfix: the resolution 1920?1080 was not saved at the closing of FluidMark.

As you may notice, particles have changed their color from vibrant yellow to bloody red, but major improvements are related to usage of newest PhysX SDK

1) FluidMark 1.2.2. does no require PhysX System Software to be installed, since SDK 2.8.4. is driverless.

When FluidMark 1.2.0. can only helplessly display error messages, version 1.2.2. starts without any problems.

2) Binary version of PhysX SDK 2.8.4. is compiled with SSE2 optimizations, and, thus, we can expect some performance gain while running FluidMark on CPU. But lets's test this out:

System: C2Q 9400 CPU, GTX 470 + GTS 450 GPUs, 4Gb RAM, Win 7 x64, 260.63 GPU drivers, 9.10.0514 PSS. FluidMark Settings: 1024x768, Async mode Off, Multi-core PhysX On, 60000 particles, 60000 ms benchmarking time, 3 emitters.

Stable performance improvement ' around 14 %. Of course, it may not be purely SSE merit, but related to internal SDK tweaks, but it is good to see a progress.

And what about GPU calculations ?

No actual difference between FluidMark 1.2.0 and 1.2.2.

Obviously, single GTX 470 is significantly faster than dedicated GTS 450, because FluidMark is not stressing system with graphics calculations. In actual games dedicated PhysX GPU will perform much better.

You can download FluidMark 1.2.2. from here

Our thanks to JeGX for pre-release version of FluidMark 1.2.2., provided beforehand
