PhysX

There hasn't been any real information whether BI will use the CPU or the GPU library of PhysX

EDIT: They have just said that they have it running on a machine with an ATI/AMD 5770

I don't see a huge benefit with GPU accelerated physics anyway. Because then the GPU has less processing power to spend on graphics.

Less performance is marginal or even none.

Thats pretty much Max Power's point...

This thread is full of people making assumptions on how physX will be implemented in A3, yet we have very little official information beyond "physX will be used"

Is there a source for this information? I must have missed it...

What about checking Confirmed features first?

I've been keeping an eye on the features and it doesn't seem like there's any source for what gnear was saying... that being very specific information on what kind of physx implementation or acceleration ArmA 3 will have.

was gonna try explain it, but can't be bothered. its all about scaling performance.

the physics wont change, same on both vendors cards... just if offloading is supported, you'll get a performance gain for having an nvidia card when lots of physics calc is going on... that is all

And it only works if its actually been implemented.

We have no confirmation either way, whether or not A3 will take advantage of hardware acceleration...

[gnear]

why not implement it, when its at the heart of the physx software? all it means is that BIS should scale the physx calc to that of their ~recommended CPU specs, regardless of the video card used.

Right. What I was looking for was your source clarifying whether the Physx implementation in ArmA 3 will take advantage of the GPU acceleration or not.

afaik, vbs physX implementation is NOT hardware accelerated
