Planetside 2 amd cards?

[Jongo]

So I like many others on the forum will most likely have an AMD graphics card, now with Planetside 2 using physx I am just wondering how this will affect performance since i assume everyone will have to run the same physics simulations to keep everything in sync.

Will it put the physics calculations to the CPU? if so will this cause much of a performance hit when using an AMD card.

I hope so AMD is so 6 years ago.

I'll find out and report back later. I have two machines that are 100% identical except for the power supply, case, and graphics card.

One sports an XFX 5830, the other has an EVGA 550Ti

Both cards are about the same. Will one run super better than the other. I doubt it. PhysX isn't always run on the card even if you have an nVidia card. The PhysX in this game is likely not the CUDA based PhysX.

Pretty sure it was said by a developer this is GPU PhysX no the CPU based kind.

I doubt it. They aren't going to alienate all the ATI/AMD people.

AMD video cards can disable PhysX. Thats not alienating.

Apart from being completely wrong, we should all want AMD to remain competitive to keep Intel/Nvidia in check.

There are, in a simplified way, two parts to physX:

#1. Rigid body game play physics: How models and parts of models, physical objects go tumbling around. Basically what Havok does. Hardware acceleration doesn't help that much it will be fine on AMD cards.
#2. Eye candy physics: particle effects, clothing, water, splinters. It will run terribly on an AMD carded system (maybe not at all). Turn it off and you're fine.

The rigid-body physics are always run on the CPU because it's not a simple calculation repeated millions of times. But particle physics are just that. You'll be able to run the game just fine with an AMD card, but your explosions probably won't have splinters in them that's all.

If you're that bothered, there are ways to harvest a secondary NVidia card specifically to enable those GPU-assisted eye candy PhysX.
