I should not also have to drop in a Nvidia GPU to process things like "physx" or "CUDA" because it is not a hardware limitation it is SOFTWARE.

I have personally achieved running physx on my current ATI 4870 by using special drivers and a super old version of physx released before nvidia acquired physx.

I can run all the demo's and play unreal III with the special physx enabled levels (meant only for nvidia cards) just fine.

So I will go back to why I am so pissed off about Cuda and physx, its all software limitations (just like SLI lock/ hacking to enable it)

Its like when cell phone makers lock boot loaders and prevent people from loading custom roms (deemed legal through a supreme court ruling).

Cuda and physx and SIL are basically illegal software locks and imposed limitations as far as I am concerned. Make GPU processing open and widely supported.

SLI, Crossfire, Cuda, physx, Havok these are all things that should not artificially limit what you can do with your personally owned hardware.

AMD vs Nvidia is like Apple OS versus Microsoft OS - when it should be more like red kool-aid vs green kool-aid.

and Im buying who ever is selling more kool-aid cheaper.
Cuda isn't all software. That's where Tesla comes in my friend.

Which is where PhysX 3.0 comes into play. I think they finally realized they need to pay attention.

Havok on OpenCL is a start but still has a ways to go:

My friend, you are wholly remiss, if u believe anything you've just typed.

Physx is just a proprietary means to market fabric physics to enthusiest as a peice meal solution for eye candy. Nvidia's "Physx" isn't special, or even good. Just overhyped & overmarketed.

Cuda is completly different & has it space in the market, but is not an open standard and has waining support.

Were you just talking to yourself now? Havok hasn't been able to reproduce anything remotely as stunning as PhysX so far.



CUDA is actually gaining more support each day. Try finding a job developing for OpenCL vs CUDA. Why are Supercomputers are Universities using CUDA? I wonder...

Yeah you're talking to yourself again aren't you....

To date no other physics engine has been able to go head to head in realism than Physx. There is proof all over the internet, including from the post above me. Your either miss informed, or just thick in the head.

PhysX is the worst engine I've seen so far, like everyone else with sense has also mentioned, overhyped and not worth a card slot, it's always liquid demos and when they do mass object collisions, planks of wood are bouncing around like rubber, I found the Havok cloth demo and Bullet physic's plank demo were much more impressive

I think you're forgetting that that's child's play for PhysX. It can do a lot more than just clothing realism. If you're too cheap to buy a 9800gt that's your prerogative but it's definitely not the worst engine...

this is the final nail in the coffin for CUDA and come on PhysX is a gimmick. just accept it

Yes...because Fermi wasn't designed totally around GPGPU computing and came out a year ago... /sarcasm

I am laughing so hard right now... Never have I seen so many talk so much about that which they clearly know so little of.

You do realize that^ is all computational fluid dynamics (which I use on a daily basis) & that it just "fabric" or "particle" physics..?

None of any of that will ever be in a game, because it requires it's own video card(s) to calculate...!

Again, Physx is just a marketing gimmick. None of the physics it uses are deformable, or real. Nvidia has just had to market "physx" well to recoup its investment from buying Agiea & Physx, only shortly after(2yrs), find that multi-core CPU's were powerful enough to handle object based physics (ie: bfbc2).

nVidia knew it could place particle physics in games to make them LOOK better. So, nvidia started marketing "physx" as a peicemeal solution for high visability franchises (ie:batman) to cash in on.

Because, today nvidia's physx solution can't compete with a generic $120 quad-core in terms of real physics (ie: not particle physics)

Here: http://www.viddler.com/explore/HardOCP/videos/36/

Take a look @ what nvidia can't do^. (That is on a 2yr old, discontinued intel quad core)



GPU physics are not for gaming, mostly for scientific use. Don't believe me... show us one game where physx does anything real like in bf3. Don't believe the hype, you'll become an unwilling shill to nvidia's marketing.
