I think I'm yet to play a game that actually used PhysX. I was somewhat disappointed to find out Bad Company 2 didn't as that's about the only game I play these days.

 

[gropingmantis]

Can someone explain to me what exactly PhysX does/is anyway....other than keep installing on my PC even though I have an AMD card.

 

[Reaper 392]

as far as i know, it just means that some physics calculations can be offloaded from the CPU, and dumped on the GPU.

 

[Kmodo]

um yeah, I have all nvidia cards and still do not care

 

[Helveticat]

In a nutshell, it adds some decent physics-related graphical improvements for nVidia cards in a handful of games.

Very roughly, there are two parts to it. Game engine and hardware acceleration. There are more games that use physx in the background, this works on anything; Pc, ps3, mac and now tablet. Then there is the hardware accelerated side. If the implemented effects are quite big (either in reality or the marketing world) they can be offloaded to a dedicated processor (gpu) This is the one that isn't compatible with amd cards becuase nvidia's marketing team love to cut their nose to spite their face.

Thank god you own nvidia cards or your opinion would have been invalidated.

 

[gropingmantis]

So if you have a powerful CPU PhysX is largely redundant?

 

[lay-z-boy]

Not necessarily, as some games have been designed to offload to the gpu and either loose the effects or perform like rubbish if you set it to run on the cpu.

I.e in batman you get a far more active/interactive environment if you turn physx up to max.

The ones that have physx but no h/w acceleration will run fine trusting the cpu is up to scratch. I.e bulletstorm or nfs:shift.

 

[gropingmantis]

Thats absurd. Is that even allowed? "You have to buy this brand or loads of your games will run like rubbish/not to their best".

 

[HangTime]

Why wouldn't it be allowed?
If anything it would be far less acceptable if there was some sort of restriction preventing innovation, basically saying to hardware manufacturers "don't come up with any new proprietary ideas or we will ban the sale of games that utilise them".

 

[lay-z-boy]

Yes, as nvidia pour huge amounts of cash into sponsoring games (think intro movies) They usually tweak the game to their favour both on the driver and engine side.
AMD do the same but to a lesser extent.

Nvidia spend up to $50m per year working closely with developers in the TWIMTBP program to ensure the latest PC games run well & sometimes include extra features on Nvidia gfx cards which is why Nvidia is the best choice for the PC gamer regardless of budget

In recent years Batman Arkham Asylum & Just Cause 2 make good use of Nvidia PhysX & Cuda technologies but HAWX2 + Lost Planet2 also look amazing in DX11 with Nvidia gfx cards.

Damn well looks like I know where my next card will be coming from...but that is what they want, damn you Nvidia *shakes fist*

Because I get some tiny extra effects in around 4 games that I wouldn't notice anyway. Nah, I'll stick with AMD thanks.

Edit- Or at least the best value card for my price point.

Bulletstorm uses Havok no?

That's because the physics engine (frostbite) Is reliant on CPU power and not gpu, so even if it supported it, it probably wouldn't have made a blind bit of difference to be honest.

Although physics (in the physx sense) in games usually means exploding and ragdolling of geometry, it can also be used for more subtle things like flowing of hair and clothing (or curtains, ship sails, flags, etc.) too.

The effect is usually subtle enough not to be a deal-breaker IMO, but the extra candy is nice if you've got it.

Yeah, people hear physics and think exploding wooden crate panels banging off all the walls and stuff. It can be applied to so much more, but most devs don't do it because the resource cost is too high.
