Physx Card? - I don't know which one it is

Yeah I really wouldn't bother with an extra card for physx with a 295... I can play mirrors edge at 2048x res, all settings maxed, physx on, 4x FSAA, 16x AF and rarely drop below 60fps - mostly 80-100 with 2x 260GTX in SLI.
 
Is it really worth having Ati 4800 series card running along side a nvidia card for physx compared to on its own?

The nvidia card runs my second monitor - I can have winamp visualisations or gpu accelerated video playing whilst I play games on my main monitor. It's a bonus that it'll also do GPU physx processing ;)
 
Look's like the PhysX is just another gimmick for the public to waste their cash on.

Dunno. I'm trying the Crystatis demo, and it runs dog slow. Like 3FPS slow. On an XFX 4850 XXX card/Q660/8Gb RAM.

Only goes up to about 25-30 FPS when teh demo goes right up close to a wall.

Are games akers seriously optimising their games that much for Physx/Nvidia [as the benchmark above suggests] or is my card FUBAR? it also doesn't do the HDR/Bloom effects properly in that [although works in 3D mark vantage].

If so, what a ******* load of **** from the games coders, and they can go **** themselves if they think I'm going to pay good money for that sort of performance. I'll just get HL2 Orange Box and play that - worked fine on my X1650 Pro...
 
Cryostatis with the physics effects on requires a hardware physics accelerator either the original PPU or a geforce 8 or higher series card, ATI doesn't hardware accelerate it so its all done on the CPU which is very slow.
 
Buggery.

Well, screw 'em, I'm not paying £150 just to get a game [never mind a tech demo] working, not when it's not the GPUs fault. both cards have over a teraflop of processing power, they should be capable of finding a better workaround than 4fps software emulation IMHO.

Any game marked 'designed for PhysX will be on my 'screw you' blacklist from now on, methinks....

Oh, and I was going to have an early night tonight. I thought my GPU was shafted so been up trying this in Vista, Win7, with hardware Physx, without, high settings, low settings - it's literally only the physics it's having difficulty with. Shocking.

And I found my steam account detail. HL2 coming down now, going to get Orange box tomorrow. Never played Portal before.

reckon it'll get more than 4fps? ;)

Nothing wrong with PhysX if it is implemented properly.

The 'problem' with physX is that it only works on nVidia cards, which mean half the market is left out in the cold, and not many games developers will want to shut out half of their potential sales. As such most go for other physics engines that can work well on both systems.

Until we have a unified physics engine game developers just aren't going to push the boundaries and implement the effects these cards are capable of.
 
I might see if I can pick up a cheap 9400 to run along side my 4780 as I read a few months ago there wasnt much point as Ati has support for directx 10.1. But then again Nvidia has support for physx and CUDA.
 
A 9400 will really struggle to run physx. it has half the cores of the 9500GT, has half the memory bandwidth, and half the texture fillrate.

It'd struggle to run Aero, nevermind Physx.

Yup 9400 won't work, its too slow.

Absolute minimum card that will give you an improvement is an 8600GT 256MB, the card really needs to have 32SP minimum.
 
Looks like the Ageia PPU is actually a good card for the Physics. (so it should be) Judging by the benchmarks anyway.

Works well for those without and SLI board.
