PhysX game shows promise

We finally got around to testing out CellFactor: Revolution for ourselves this week. To recap, CellFactor is a free downloadable game designed to show-off those fancy Ageia PhysX cards we're sure at least two or three of you may have purchased for your gaming PCs.

CellFactor is basically a straightforward fragfest, either with bots or with real players over a LAN. You can choose from three difference character types, but we spent all of our time with the Bishop character, whose psi-powers seemed best suited to trying out the advanced physics.

We definitely experienced some ooh and ahh moments while playing CellFactor. Psychically redirecting a stream of flowing, blobby lava into an enemy's face is new. We also liked the various tricks you can pull off with the plentiful objects in the game, such as gathering boxes in a floating formation in front of you and then firing them at your enemies one by one. Being able to part rubble like the Red Sea is fun as well.

We didn't conduct traditional benchmark testing with this card as that seemed fairly pointless; what would we compare it to? But we can say that we tried it in two different PCs of varying capability.

The first was a Gateway FX530XT, complete with 4GB of RAM, an overclocked Intel Quad Core Extreme chip, and a GeForce 8800 GTX graphics card (an update from the last Gateway we reviewed). That system handled the PhysX card fine at 1,280x960, with all the graphical bells-and-whistles turned on and the frame rate holding consistently at 40 frames per second or so, which was very playable.

The Gateway DX430X was less speedy. It has a decent 320MB GeForce 8800 GTS card and 2GB of memory, but its 2.13GHz Core 2 Duo E6420 chip is a fairly mainstream part. Its frame rate probably averaged around 25fps, but it was still able to handle most of the scenes without chugging too hard. If we'd turned off motion blur and the HDR lighting effects, it likely would have been faster.

As to whether it's worth shelling out $150 for the PhysX card, we don't think CellFactor is deep enough. It's a good start, since it shows off what the technology can do, but we're more interested to see if any of the forthcoming PC games with announced PhysX support will implement hardware accelerated physics in a meaningful way. There's always the chance, but we have a feeling that for now, developers will simply stick to boosting cosmetic effects, rather than risk alienating potential customers by requiring a PhysX card to power a fundamental game element.

The product is a tough sell

I think the whole PhysX card is a tough sell for many outside of the hardcore gamers. My thoughts is that the company will eventually get purchased for their ip by AMD or NVidia and integrate the chip as a specialty core in a multilevel chip.

I think it can gain momentum..

I think people should note that the same thoughts of a "tough sell" were the norm when the first 3D graphics cards started hitting market.

Second, PC gamers who would care about physics are certainly the type to buy something like this. The Unreal 3 Engine, which Epic sells to other companies, supports this PhysX acceleration. It will be in many new games coming out, and makes this product much more alluring.

All they need to do is drop the price to hit the 100-125 mark, and people will jump on it.
