Mafia II Demo: PhysX Usage

with 32 comments

While you are waiting for Mafia II Demo, planned to be released just in a few hours, you can read the preview of APEX/PhysX content, prepared by Techgage in their “Taking a Look at Mafia II and its PhysX Use” article.

Demo includes “Benchmark” mode, and that’s how it’s look like:

Update: Our PhysX Comparison video using built-in benchmark. In addition, APEX comparison and showcase videos roundup.

Update #2: Tweaking PhysX in Mafia II – huge fps increase without noticable difference.

Update #3: Mafia II Demo – PhysX Benchmarks roundup

Update #4: Mafia II GPU PhysX profile – comparison video, screens and other additional info.

APEX/PhysX Features:

  • Physically simulated clothing for main character and additional characters
    • Custom wind simulation that creates a more dynamic movement of clothing as the characters walk around and interact with the environment.
    • Force fields from explosions and interact with clothing, making those explosive moments even more immersive
  • Up to 3,000 unique particles on screen at any given time (10,000 at High settings).
  • Particle effects including dynamic collision, mass and kinetic simulation, and force fields from explosions that move and displace particles along its path.
    • Destruction particle debris from cement, wood, glass, dirt, and more
    • Weapon impact that creates dynamic smoke and kinetic persistent particles
    • Garbage moves and exists in the world of Empire Bay and reacts to effects like force fields and character interactions
    • Tire burnout while driving produces dynamic smoke and particles including fluid movement simulation and particle velocity and trajectory
  • Character clothing on all character models is rendered entirely on the GPU when using a dedicated PhysX card which can be anything from a GT 240 to a GTX 480.

With APEX set to “Off”:

  • Clothing on character models is not realistically generated but graphically simulated. It does not interact with the physical world.
  • Particle debris is sprite based and does not contain physical properties. Particles will not interact with the environment and are not persistent.
  • Smoke is staticly generated with no physical properties and will not interact with the physical world.

P.S. Judging by demo, additional APEX PhysX content is optimized for CPU execution better..

..than previous games, like Dark Void.

Unfortunately, still not enough for decent fps and comfort gameplay (at least, with our C2Q 9400 CPU).

PROBLEM: Strange. According to PhysX Visual Indicator, PhysX effects in Mafia II are running on CPU, even if GPU PhysX is enabled in drivers – with this newest 09.10.0512 System Software.

I wonder if that’s the reason of low fps. Can anyone confirms this ?

SOLUTION: you need to reinstall PhysX drivers.

Uninstall current one, than install PhysX_10.05.12_9.10.0512_SystemSoftware package manually,

from \Steam\steamapps\common\mafia ii – public demo\3rd

  1. 9.10.0512 seems to be older than 9.10.0224 according to its digital signatures and file versions.

  2. hybrid physx does work on my 5870+9800gt with the PhysX benchmark inside(1680×1050,ALL MAX settings include APE PhysX, without hybrid physx, the avg fps is 12.2fps, with hybrid physx, the avg fps is 25.1

    I heard GTX 480SLI get similar result with 2xfps in the PhysX

  3. Yup, hybrid works as long as you remember to reapply the hybrid physx patch after installing the demo.

    I got 31,1fps with an overclocked HD5870+GT 240 (everything maxed, 1920×1080).

  4. all settings maxed out @1680*1050 q6600@3,2 stock HD5850 + physx@8600gt ddr2 pci-e x1 (cough…cough…))) bench shows average 21fps

  5. GTX460 and C2Q Q8400 – after manual reinstall of physx 0512 visual indicator shows physx through gpu but for some reason gpu is working just at around 30%.

  6. But my point was that currently it is impossible(or nearly) to set PhysX up in a way which is entirly GPU driven
    Well, I don’t think there is going to be a huge boost from closed physics-rendering cycle entirely on GPU anyway.

  7. Tip on how to vastly improve the FPS when using physx.

    Well, looks like exactly as our guide ;)

    So if you used our data, it would be better if you provide link to original article.

  9. Oh sorry Zogrim, i actually read this on the 2k forums, wasnt aware that you had a guide up :) Well its almost the same as your guide, this doesnt remove aaall files in Clothes folder ^^

    If ya want i could link to your guide? =)

  10. Well its almost the same as your guide, this doesnt remove aaall files in Clothes folder
    Full or partial (remains for Vito) – it is all decribed in our guide. And it was released earlier – 17 hours ago from current time.
    Anyway, it does not matter.

    If ya want i could link to your guide?
    It’s up to you to decide

  11. Cool ,i got 30.4 fps .
    1920×1080 no AA +16AF all on MAX and High PhysX
    DDR3 1600Mhz 4Gb
    Cpu-phenom 2 720 BE 4 cores 3.6Ghz
    GPU -HD5870
    GPU -GT240
    Both runig at 8X speed.
