Benchmarks: PhysX On/AA On (Dedicated PhysX)

The near devoted of PC gamers won't heed calculation a second graphics card to offload PhysX processing. In this example we used a defended GeForce GTX 460 to handle the task. We re-tested Mafia Ii with PhysX enabled (loftier) on both Nvidia and AMD cards.

Annotation that this typically won't work for AMD users equally the GeForce GTX 460 cannot exist set to handle PhysX, withal using a software mod (Hybrid PhysX mod v1.04ff) it is possible to set up things upwardly in proper fashion.

By adding in the GeForce GTX 460 to handle PhysX we were able to boost the performance of the GeForce GTX 480 past 24%, which is not that bad. The GeForce GTX 470 saw the exact aforementioned functioning boost every bit frame rates went from 38fps to 47fps.

Surprisingly the GeForce GTX 460 did very poorly when adding a second carte du jour for dedicated PhysX with a mere 3fps crash-land. Older previous generation graphics cards such equally the GeForce GTX 285 did well when paired with a dedicated PhysX card. The GeForce GTX 285, for example, saw a 23% performance increment.

The Radeon HD 5970 combined with the dedicated GeForce GTX 460 still but averaged 42fps. Not a bad result per se, just it'due south only a single frame faster than the Radeon Hard disk drive 5870. Although the Radeon HD 5870 was able to beat out the GeForce GTX 470 quite comfortably in all the non-PhysX tests, it was slower here regardless of the dedicated add-in lath.

With the GeForce GTX 460 working in the background, the Radeon Hd 5850 and 5830 cards were able to comfortably break the 30fps barrier. Fifty-fifty the Radeon Hd 5770 and 4890 were able to render at to the lowest degree 30fps.

At 1920x1200 we observe that the GeForce GTX 480 and 470 performance is however very strong with both cards rendering well over the required 30fps. However performance drops off sharply when going to the adjacent fastest graphics cards being the GeForce GTX 460 and GeForce GTX 285, both merely averaged 31fps.

The red team does much meliorate at 1920x1200 with the Radeon Hard disk 5970, managing to shell the GeForce GTX 470 this time. The Radeon HD 5850 scraped in with 31fps while the Radeon HD 5830 averaged just 30fps.

Now at my favorite resolution of 2560x1600 nosotros see that the GeForce GTX 480 received merely a small assist from its dedicated PhysX menu with a small 2fps boost. We found a similar story when looking at the rest of the Nvidia range.
