It shouldn't as physical data load should be the same for 3D it's just rendering the image twice from two slighty different angles. And for those two frames the physics data should be exactly the same.Quote:

Anyway, I think the recommended specs are highly exaggerated. Otherwise the number of effects would have to be enormous. I guess will have to wait and see.

They choose PhysX because Nvidia gives them money, not because it's better, which is not.
i think this game will decide the future of physx. Another nothing special situation will hurt physx too much.
Well perhaps this:Quote:

Honesly, if Batman: AA couldn't do it, Mafia 2 won't either.Quote:

Dedicated PhysX has not hit it off yet, and i dont think it will ever hit it off, below is the list of games that support hardware accelerated physx.
Batman: Arkham Asylum
Crazy Machines II
Cryostasis
Dark Void
Darkest of Days
Tom Clancy's Ghost Recon Advanced Warfighter 2 (GRAW2)
Metal Knight Zero Online (MKZ)
Mirror's Edge
Nurien
PT Boats: Knights of the Sea
Sacred 2
Star Tales
Unreal Tournament 3
Unreal Tournament 3: Extreme Physics Mod
U-WARS
Warmonger: Operation Downtown Destruction
just downloaded the mafia 2 demo from steam. it seems like physx is available on cpus as well - atleast i can set it to normal and high in the ingame menu. however, even on high, it doesn't really add anything special to the game. the shrapnels etc look horrible, like 2d bitmap images. lol.
however, the performance kinda sucks, even with physx off. ran the ingame benchmark and the result was 36fps. seriously, the game doesn't look any better than every average game released in the last 2 years. the graphics don't offer anything that could justify this performance. i'm pretty disappointed.
*edit*
@HelixPC: the original UT3 never took advantage of physx. the only thing that does is the physx mappack that has been released and specifically designed to showcase physx. there's not a single map in the original game that uses any kind of physx, as there's no physics in the maps at all. the engine supports it, yes, but it's not used except in the mentioned physx mappack. this mappack makes heavy use of physx so that everyone without a phsyx ppu/gpu can't play them as frames hit the single digits after like 1 minute, so nobody plays these maps online...
Also Mafia II Benchmark: PhysX ComparisonQuote:
APEX/PhysX Fetures:
- 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 form 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.
http://physxinfo.com/news/3617/mafia...sx-comparison/
looks pretty balanced honestly
with it on you get alot more particles that stick around and dust from bullets hitting thigns. with it off you still have destructible environments, flying objects, fire looked the same
Thats scripted animation in combination with computed physics.Quote:

Performance is good for me :)
Average Frame Rate of 58FPS at 1920*1200, no FSAA, and Physx set to Medium, everything else is set to HIGH...this is on a GTX 295 single PCB and QX9650.
Gameplay was smooth and fluid, however in a few areas I got occasional slow downs for no apparent reason, however the demo was fun to play.
Sadly with Physx set to high, the GTX 295 hates it. Average frame rate plummets to 31FPS.

Looks like either Nvidia, or 2K Czech need to do some serious optimization/driver tweaking for this game.
I just ran the benchmark (2560x1600 everything maxed), and I got horrible FPS!
I checked MSI Afterburner afterwards, and my GPU usage was really, really low (around 20%)...which explains the low FPS.
Also, my dedicated PhysX card wasn't even utilized! :shakes:
check your cpu usage, and if its low set it to work on only 2 cores and see what it is then. and if its clearly working on a set number of cores, OC and see what it does
CPU usage was fine. My CPU had slightly over 20% utilization, on multiple cores.Quote:

It has to be a driver issue, as the demo was just released today..
the usage across cores does not show if its limited to 2 threads, windows will throw that all over the place.
if your seeing no core max out, then your not gpu, or cpu limited, even with bad drivers i dont expect the issue to cause such a weak consumption of resources
but the fact your already overclocked should let you get 60fps, but you are running a really high resolution too.
Nvidia wil probably come with a beta a day or 2 before the game goes retail.Quote:

Graphics are important but gameplay is a lot better. I can have fun even with and old mario cart 64, or old duck on my old nintendo on my full HD led tv :D
Gameplay is the most important.
In a game, you must absolutly feel good. It's a game, it's time for pleasure, not time for frustation.
For feel good you must have;
1-an easy understandable world, and easy to take in hand.
2-nice graphics, but not too heavy for a modern PC, It should run smouth on most PC, and the most important, not highly difference in quality in two differents things in games. This is very important, objects and sets must be of the same quality.
3-No too scripted world, or your must hide your scripts the most of the time. It's a game, not a prison.
4-Good musiks, take example on half life 2. Did you know there is 51 original titles in that games ?
5-The best one, a good ambience. You have to be attracted, you want know the end, you want have fun, you want have fun.
Mafia II demo seem good, not perfect. I played crysis warhead today, was a crap game, nice graphics, but no fun, to shoot auto and miss evrything.
I prefer don't waste bullet. This is the first rule that said my grand mother. ( i joke ^^ ).
The performance issue I'm having is definitely tied to PhysX..
Turning PhysX off, I get greatly increased activity on my 480s, and my framerate increases tremendously.
With it on however, the framerate is horrible.
I think the reason is because PhysX is being run on the CPU, rather than the GPU. Maybe this discrepancy only affects systems like mine that have a dedicated PhysX card :shrug:
Carfax, other expressed the same problems (PhysX running on the CPU even with NVIDIA GFX) and they solved it via installing the PhysX driver that is included in the installation folder (3rd).
Yep, try uninstalling PhysX and then reinstalling it from the game's directory. Apparently it doesn't install properly or something and it runs on the CPU. Can't remember where I saw it else I would drop a link.Quote:
