You may recall that PhysX trailer from a couple of weeks ago which shows the technology the PC version of Mirror's Edge is capable of utilizing. Well, a comparison video now online should give you a better idea of whether or not to upgrade, if you were thinking about it. Video at the source.

Here is the side by side video showing better what DICE has added to Mirror's Edge for the PC with PhysX. Please note that the makers of the video (not us) slowed down the game during some effects to better show them off. The slow downs are not performance related issues. Also, the video is best viewed in full screen mode (the button in the bottom right corner).

The effects in there can be simulated on either a CPU or an NVIDIA GPU. The advantage to the GPU is performance and NVIDIA indicates that even an Intel Core i7 processor will have a tough time without GPU support. So these effects aren't anything we've never seen before, but it certainly looks like there is just a lot more of it in Mirror's Edge (and not in that really bad too many particles/too much debris sort of way). The glass breaking itself honestly looks the same (or close enough) to us, but the persistent particles are where it's at. Having a little debris stick around and be affected by the character is a nice touch. The cloth, plastic and tarp effects are what look like the real icing on the cake in the game though. The complete absence of the cloth objects when physics is disabled makes an already sparse looking world look pretty empty by comparison.

We still want to really get our hands on the game to see if it feels worth it, but from this video, we can at least say that there is more positive visual impact in Mirror's Edge than any major title that has used PhysX to date. NVIDIA is really trying to get developers to build something compelling out of PhysX, and Mirror's Edge has potential. We are anxious to see if the follow through is there.
