So I'm upgrading to an HD 7870 soon ! Then of course I'll have my old HD 4770 available for other kinds of nonsense. So, I was thinking. would it be possible to use that second card to handle physx? Like, I know its supposed to be an Nvidia thing, but I saw the option for physx somewhere on my current ATI card's settings, can't remember where I saw it though! GRRR (there were four boxes to tick, Direct Compute, Open GL, i think, Cuda and physx) If this were indeed possible, how would i go about setting it up and connecting it. I have a strong enough psu.
aaah oky makes sense thanks! I just thought that since Physx can work on a CPU it would work on an ATI card. Sure it wouldn't be optimized but I wouldn't need it to be since the HD 4770 would properly be plenty powerful enough to run it. Also I read somewhere that you could but I could be mistaken... Thanks anyway!
That is showing how you can run a NVIDIA card as like a secondary card with an ATI card as the primary GPU. So like if you were to run your soon-to-be 7870 with say.....a GTS250 like I have, they have hacked drivers to do so (I've done it)
I read further after I posted and sort of guessed that, but I just wanted to make sure. BTW is Physx such a big improvement or is it just hype? I could imagine having better physics calculations would help a great deal in racing games, but we're already so close to real life, is it really needed?
