FluidMark 1.2.2：首个采用 SSE2 指令优化的 PhysX 程序发布

Edison

A new update of FluidMark, Geeks3D’s PhysX benchmark is ready for downloading. The main feature of FluidMark 1.2.2 is the compilation with the latest PhysX SDK 2.8.4.4.

The direct consequence of the use of PhysX SDK 2.8.4.4 is the use of the new driverless model. No longer need to install the PhysX System software to enjoy PhysX. Now any PhysX app can embed all necessary PhysX files and that’s exactly what FluidMark does.

And the cool thing is that when NVIDIA will release an update of its PhysX System Software, just install it and FluidMark will use the new PhysX runtimes thanks to the update system in the new PhysX SDK (see HERE for more details).

Other interesting consequence of PhysX SDK 2.8.4.4 is that the engine core is compiled with SSE2. So CPU PhysX takes advantage of that and from my first tests, there is a gain (not a huge gain but a gain anyway):

FluidMark 1.2.2
- CPU: Quad Core X9650 @ 3.2GHz
- 60000 part, Multi-core:ON – Async mode: OFF
- Res: 1024×768 windowed
- Global SCORE: 65 points (60000 ms) – CPU PhysX
- PhysX: 65 (11 SPS) – GraphX: 65 (11 FPS)

FluidMark 1.2.0
- CPU: Quad Core X9650 @ 3.2GHz
- 60000 part, Multi-core:ON – Async mode: OFF
- Global SCORE: 57 points (60000 ms) – CPU PhysX
- PhysX: 57 (10 SPS) – GraphX: 57 (10 FPS)

See this post and this one for additional details about PhysX and FP87 / SSE2.

PhysXInfo has done some performance tests. You can read PhysXInfo’s article HERE (english) or HERE (russian).

I changed the post processing effect because the previous one was subject to some misunderstanding (see HERE ):

I also restricted the online score submission. Now only scores in fullscreen mode, without AA and without PostFX can be submited. The same kind of restriction will be used in the upcoming FurMark.

What is FluidMark?

FluidMark is a fluid simulation benchmark based on NVIDIA PhysX engine. The fluid simulation uses the SPH or Smoothed Particle Hydrodynamics method where interparticle forces are considered (SPH requires more CPU or GPU horsepower!). FluidMark support both CPU and GPU PhysX and in CPU mode, multi-core CPUs are supported (see HERE).

PhysX FluidMark 1.2.2 changelog

• Change: new post processing (post-FX) effect.
• Update: compiled with PhysX SDK 2.8.4.4.
• Change: scores submissions are limited to fullscreen mode + No AA + No PostFX.
• Bugfix: the resolution 1920×1080 was not saved at the closing of FluidMark.

能有多少提升呢？I家自己的havok不也是以X87为主体的吗？

成绩不是已经在上面吗？ +10% :p

顶起。。。。。。。

SSE4.2是杯具吗？只能用SSE2？
提升只有10%？

你们忘了AVX
不用AVX，就是劣化！
