Physx never read much into it ..

[rippling]

Until now , i always had ati gfx cards but seeing demos of say batman aa with and without physx it looks far better with ie more atmosferic ,i am not saying effects couldnt be added without it but it does look good cany wait to get my gtx580 now , do you need 2. Cards for it to work or will it work on one ?

 

[strumpusplunket]

Yeah, Batman is much nicer with PhysX on. I think it's one of very, very few games you can say that about, though.

I run it with all settings maxed and PhysX on normal at 1680x1050 with my GTX460. I can run it okay with PhysX on high, but for some reason my sound tends to distort when I do (yeah, go figure...).

A GTX580 will rip through it like a hot knife through very soft butter.

I will be using it for 3d as well hope it will still cope

 

[strumpusplunket]

Yeah, even taking that into account, I'd be confident it would cope admirably. Unless you're talking about 2500x1440 or something...

 

[rippling]

No no 1900x1200 at most dont expect it to cope with metro but i put that down to poor coding with that game i mean everything is dark how can it be so power hungery

i'm confused. i like you OP have never known much about physx or tried to use it but when i see people talking about it on here, i see them saying they use an older graphics card specifically for physx? what's that about? do you need to set up a different card specifically for physx? i am just setting up a new machine, running gtx 570 sli. i guess i should be ok to use physx then without anything additional?

 

[strumpusplunket]

Yeah, if you have a mid-range single card, a separate card functioning as a dedicated PPU can help. TBH, so few games actually use PhysX effectively I'd not bother investing in a separate card.

I mean, it's nice to have, and it does improve Batman, but my 460 works fine as a single card in that game, and I can't see me wanting to shell out even for a cheapish 9800 just to get better PhysX levels in any other titles. It would only benefit maybe two or three games, and even then not to a game-changing extent.

Two 570s should power through okay anyway...

Edit: all IMHO, of course. I realise different people set more or less store by PhysX and its game implementations than I do. YMMV...

 

[Confused]

I've never really looked into PhysX, either, until the last couple of days.

I've got a thread here about my experiences, although I've been getting it working with an ATI card as my main card


Now I've got it, there's no need to remove the card. As I've not paid anything extra to do it, it's worth doing.

However, I wouldn't *pay* anything extra, just to do it.

 

[rippling]

So do we need a seperate card for it or will one 580 handle it all ?

 

[Rroff]

For anything out atm except Mafia II theres no advantage adding a dedicated PhysX card in alongside a GTX580. In Mafia II the game will run far smoother with a dedicated card for PhysX rather than sharing the rendering card but its hardly worth doing for that one game.

When customers come into my shop and say they want an NVidia card for phsyx usage, I ask them to name the titles that use it, and then hold up my hands and count 'one, two, three...' as they name the three titles that actually use it very well...
