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 #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.
- 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.
SOLUTION: you need to reinstall PhysX drivers.
Uninstall current one, than install PhysX_10.05.12_9.10.0512_SystemSoftware package manually,
