[TH]Physics Drivers Outrage

But this move was "too little, too late" for companies like Epic and Futuremark, who made their design calls years ago. AMD didn’t work on GPU Physics and even tried to bury it. As a result, PhysX has become the physics API of choice for more than 150 games and Futuremark used PhysX in its benchmark.

Higher framrate = higher score, period. There's just no way around it. And when I use physics acceleration in physics intensive games, my frames go up, so AMD can quit whining.

And I love this statement from AMD:

Who cares if the graphics are scaled down a bit? More physics mean more fun.

how exactl;y did you get that framerate equation from an article entireley about physX

All I'm saying is that AMD is undermining the benefits of GPU based physics processing in order to dampen the public's view of Nvidia products simply because AMD hasn't developed a counter product yet. It's marketing, no more, no less.

Also, Vantage is a benchmark that--call me crazy!--is pretty heavily dependant on frame rates.

Picture quality man picture quality. Right now thats what I care about. And as long as I have 30fps I'm happy.

physics acceleration doesn't work (isn't supported) by the 8800 series. I've tried everything possible to get PhysX to work on my 8800GTX, no dice.

Nvidia has physics process on the graphics card, ATi does not, there for nVidia has high scores. A bit unfair for ATi/AMD but we would all be just as outraged if Dx10.1 was giving AMD an edge while leaving nVidia out in the cold.

The difference is that NVidia has the monetary power to bribe devs not to use DX10.1. ATI can't do the same thing to PhysX. So I consider that unfair.

I still think physics should be run on the CPU...

Most games heavily use 1 core, and the other core (or other 3 for those with quads) are relatively unused.

GPUs are almost always running at 100% utilization in modern games, so shouldn't we be running physics on the CPU?

I haven't done it on my computer, but I have friends who have the hardware to offload physics processing from the CPU.

Look, I don't know what we're arguing about here. If you don't know that FPS can go up once you offload physics processing from the CPU to the GPU or PPU, then you are delusional.

Uhh, not really. The only thing I'd be outraged about was that Nvidia wasn't keeping up.
