PhysX

Recommended Posts

Hey guys, what's up?

 

I've got a question about PhysX, more specifically, the function and performance of having a card dedicated to PhysX.

 

I'm not really sure how the system works, so if someone could explain it to me, I'd be grateful.

 

I have a GTX 260 on one rig, and a GTX275 on another rig. I have been entertaining the idea of purchasing a 400 series card. And moving the GTX260 as a dedicated PhysX card for my GTX 275 rig. My question is, would there be any noticeable difference in performance for an obsolete card.

 

Currently playing:

 

Sykrim

Battlefield 3

Dead Island

Bulletstorm

 

 

Thanks guys!

You would have to test the setup to see what happens but in my experience with many games and benchmarks it does not make a difference. Play the game and see what happens.

I've yet to find the "killer app" that makes me want to use PhysX.

You can end up bottlenecking high end SLI/xfired cards with something less than a GTX 460 1GB, but for what you have, you'll be fine.

Is it possible to use an AMD video card and then add an Nvidia card for Physix only? The 990fx mobos allow for either brand cards.

No, if phisX detects a non-Nvivda card it disables it.

You can use a hack to enable PhysX with AMD cards, it just means you'll need to install an executable and select the SLI hack or the normal Windows boot before loading Windows.

This little registry 'mod' works just fine and has since I started using it last year.

@OP: it will be waste of money IMO.

There will be very little improvement in the performance that you can't even notice normally.
