IGPU FOR PHYSX?

[spankingtexan]

Good evening all,

I have a 4770k but have disabled the IGPU, I also run two GTX 780's sli and was wondering if it's worth enabling the IGPU and dedicating it to PhysX, if that is possible? If so, would there be any advantage or disadvantage to doing this.

Thanks.

No.

Unless its an nVidia brand GPU (which it won't be) you can't run PhysX on it and even if it was I don't think theres a fast enough iGPU to make it worth using and would bottleneck the 780s instead.

OK, thanks, i'll leave it as it is then.

If you have a GTX660 or better hanging around, use it as dedicated PhysX.
(anything less than 650ti will just bottleneck the 780).

And that was something we were discussing today with a colleague. He upgraded to a GTX780 last week and is using his old GTX680 as dedicated PhysX while playing Batman and Planetside 2.
(while trying to persuade me to ditch the 7950s for a GTX780)

You might get better performance with just the 780.

Imagine the heat (possible throttling for main card) and power usage of a card that is just discrete Physx.. it will still run on high power usage and clocks. (Referring to the poster before on having a 660 or better as PhysX.

780 will do fine in PhysX usage.

The only reason for a Discrete PhysX card I can see is if you run a watercooled setup and you have 3-way SLI + 4th card just for PhysX because Sli 4 way doesn't scale properly (Or 2+1).

Tried running physx on my 3770k in batman, in short dont bother its not up to the task unfortunatly

How you tried by using an AMD graphic card?

PhysX is Nvidia exclusive.
