[color=#000000][font=Arial, sans-serif][size=3]The graphics pioneer has distributed its Nvidia PhysX and Nvidia APEX development kits to PS4 programmers to help bolster the machine's visual capabilities.[/size][/font][/color]

[color=#000000][font=Arial, sans-serif][size=3]PhysX and APEX tech can be used to create cutting-edge collision detection in games, as well as simulate rigid bodies, clothing, fluids, particle systems and more.[/size][/font][/color]

[color=#000000][font=Arial, sans-serif][size=3]"Great physics technology is essential for delivering a better gaming experience and multiplatform support is critical for developers," said Mike Skolones, product manager for PhysX at NVIDIA. [/size][/font][/color]

[font=Arial, sans-serif][color=#000000][size=3]Odd that they are going with AMD APU but will support nVidia PhysX, but it is a welcome addition.[/size][/color][/font]

Don't bet on this contributing to the overall gaming scene. Nvidia is desperate after loosing contracts and they still won't open up PhysX to AMD etc.

NVidia kinda screwed themselves in the nextgen console markets..... of course that all started with them suing Microsoft over the first xbox that they did have their chips in......

PhysX has been supported on the previous consoles as well as the PC using NV or AMD cards, it'd be stranger if it didn't support it.

You can use PhysX with an AMD's card. Only it tanks the fps, as the result of the cpu doing the PhysX instead of the GPU like with Nvidia's card.

No it hasn't. There's no hardware accelerated physx if you use an amd card.

CPU isn't "hardware" enough for you :) ?

I believe they mean dedicated hardware..... NVidia had their chips setup so stuff like CUDA and PhysX could happen without and real CPU degredation or GPU degredation if you offloaded it to a dedicated card for PhysX or dedicated some cores of the main GPU to handle that task

There's also no hardware accelerated PhysX on either the PS3 or Xbox 360, but it's still there. PhysX doesn't only offer the hardware accelerated version you know? It was software only first.

Yes, i am aware of its software side on the cpu. But it's the hardware side that makes the real difference.

Many have argued if it were properly optimized on the CPU side it would be hardly any difference at all.

Although that analysis isn't relevant to the newer versions of PhysX (especially 3.x) it still points out not everything is as NV would have you believe.

The way I understand it is that PhysX uses ancient code to run on Nvidia GPUs, purposefully done so that other cards cannot obtain the same performance benefit. At some point ATI drivers got hacked to fully support PhysX but it was blocked by Nvidia.

Microsoft sued Nvidia because Microsoft didn't have in the contract to re-negotiate price from nvidia for the xbox at latter time as parts got cheaper, Microsoft (per contract) was paying full price the entire time. Microsoft was kinda asleep at the wheel on that one.

Yeah but the old consoles had fixed pixel and vertex shaders and didn't have the capability for hardware accelerated Physx, the next gen consoles have GPGPU functionality, I was under the impression that it would be hardware accelerated on the new ones.

They'll still be AMD parts. PhysX could easily work on AMD cards if it wasn't for the marketing benefit NV gets.

But yeah, I would hope so.

Why is this news?

Doesn't the 360 and PS3 support PhysX?

Did you even read the thread?

Current gen doesn't have the hardware to run it hardware accelerated, the new consoles do, so its safe to assume that games could be PhysX accelerated considering the PS4 conference showed off hardware accelerated physics.

I read the OP and it showed nothing newsworthy, unless APEX is new to console support.

Does not change the fact that the current gen consoles support PhysX.

Otherwise, I would've commented: "Oh yay, consoles finally get to use something we've had on PC since 2005".
