My systems running just fine.

As i tried to state in my post. Physx is something to be endured - not enjoyed, and turned off whenever possible. You'd get far better gameplay experience by simply adding a few texture/lighting mods.

And just what is it exactly that you enjoy about running physx????? Where's the benefit?????
When has physx ever looked or been even half-decent?????

Alot of new console games use PhysX. I know that does not make PC guys feel good, but PhysX is being used.

What's a console

Are you trying to say to say games can be played on something other than a PC.

I don't believe you!

If you're using a single 560 with Mafia 2, then no, you're not fine. That's what was causing the frame drop and poor performance of PhysX.

yes its almost dead, its a unoptimized - crippled on purpose joke..


Now if they put a little effort and make it fully multi core aware and get rid of x87 code + port it to OpenCL it could have a new start, but from what i've seen its one doomed engine, Bullet physics it 100x better alternative.


And they're trying with Apex clothing and U3E dx11, i just hope it will be optimized otherwise

Well if a single 560/460 can't handle physx then what's the point. Most of the PC gaming market owns mid-range cards. Most people aren't going to spend £400+ just to enable a feature (which can be debated as to whether it actually adds any benefits or not).

Hardly good business from Nvidia. More like a blatent and somewhat desperate attempt to market something they probably wish they never bought.

And i don't see how buying a cheap dedicated card is a viable solution as 9 times out of 10 it's just gonna bottleneck your main card, leading to more poor performance - kinda defeats the whole purpose of trying to build a powerful gaming machine.

No, it's the splitting of resources that cause the lag. A sub-$100 9800GT would have helped.

I don't think it's reasonable to have to buy a separate card just for PhysX either, but if you don't it severely hurts your normal gaming. PhysX can be pretty cool, but you need the hardware to power it; it's still going to do better than running it off the CPU of even a 990X though. Too bad it's locked down to only Nvidia though or more game developers outside of the ones already paid by Nvidia to do so, would spend the time developing for it.

So can i still expect poor performance when i go SLI (another 560 2gb), whenever i turn on physx?

Wouldn't that essentially tie the 560 to the performance of the 9800gt? The game could only be run as quickly as the 9800gt permits - hence the bottleneck.

However, Intel then bought out Havok and killed HavokFX. Due to this, NVIDIA then decided to aquire Ageia since they had physics solution. The fact that some of Ageia's staff were former NVIDIA employees made it easier.

Most likely NVIDIA did offer PhysX to ATI but ATI refused since they would be tied to their competitor. Instead, ATI wanted to use something more open like OpenCL and Bullet... but ATI traditionally has been weaker on software and developer support.

Basically, my take on physic acceleration is... Intel delayed GPU physics on purpose to improve their CPUs and launch their GPU Larrabee (which failed).
I believe nVidia wanted a stupid amount of money to license PhysX to AMD, which is why they passed.
