Well done Chris. I have been debating on whether using my old card for physx was worth the power consumption. Seeing how few games it makes a difference on is definitely a factor to be considered.

The article’s title should be “How Does Having a Dedicated Physx Card Affect Games That Don’t Use It?”, then. Your title implies that you’re using the card for its intended purpose, which you clearly aren’t.

The purpose of this article is show how using a spare graphics card as a dedicated PhysX processor will affect performance.

We used a variety of games, some older, some newer, some Nvidia PhysX enabled, some not. This was to show how using that spare card may affect performance.

The games we chose are apart of our regular game testing suite, with the exception of Batman Arkham Asylum, which differs from Batman Arkham Knight because it was created with the intention of having a PPU process PhysX as well as a GPU.

Yes, we know Witcher 3 is “CPU Only” when it comes to PhysX, but it’s an example of how the dedicated card is not beneficial to Witcher 3 performance, thus confirming that the game is best played with the CPU to process PhysX.

The article’s intention is not to compare PhysX-enabled games, but to simply show how setting your older graphics card to solely process PhysX can affect different games.

For example – look at GTA V, a game with no intention of PhysX when being created, yet it had a higher average FPS with the dedicated PhysX processor. Something we didn’t expect to see in the slightest.

We appreciate your comments, and possibly in the future we could look at only comparing PhysX enabled games and the difference in their performance.
