Forceware 257.15 beta ( yes, the bug version) + PhysX 9.10.something driver + Hybrid PhysX 1.04FF = shit scores at fluidmark (89)
Totally intended or i failed hard making the drivers to work?

Complete spec on attachment. Thanks for helping, or at least leave some bash/helpful comments

>ATI + NVIDIA on same system

try an earlier version of the nvidia driver

later versions have blocked the working of an nvidia card with ati cards where ati is the main card

From my research, the 257.15 driver can work as PhysX even there is a ATI card, apparently is a bug as they said

perhaps that bug only affects certain types of card

check the CUDA checkbox, as far as I know physx works due to CUDA, so not sure why cuda is off but physx is on

Make sure you don't have any older conflicting drivers as well.

that bug was fixed but they didn't rename the driver. so you might have got the fixed version of that driver

Just wondering, how do you have 2 cards...?

AhMunRa · Posted: Thu Sep 16, 2010 6:02 pm Post subject:

Multiple PCIe slots. You could always have more than one video card.

Could be a few, why he has 2 cards from dif manufactures I don't know. Before cards had dual outputs though I used one to have a secondary display.

In this case though, it may be cause the ATI card supports Cross Fire.

In this case it is because ATI cards don't have support for NVidia Physx acceleration, but with a cheap card that does support physx you can use that

Not all cheap cards can support PhysX, they start with the GeForce 8 series, but one thing that most people don't talk about is does a higher-end card have a better performance in PhysX then compared to a low-end card?

Also if Ageia were to sell them PPU for around $100 or less, they might still be standing here today instead of being gobbled up by Nvidia.

I wish NVIDIA started to sell PPU cards too, I don't want to be stuck to NVIDIA graphics card to have PhysX... Don't want to use PhysX mods either since they don't always work.
