How Taxing Is Physics

ntdouglas · Dec 27, 2008, 05:14 AM

Guys,

The title says it all. How taxing is physics on Nvidia cards? Has anybody researched or experimented with it? As you can see in my system specs I'm running 2 9600gt's in sli. Would adding an 8600gt for physics only increase performance enough for the money?

I'm pretty sure dual 9600's can handle gaming + physX easy. Not like anything is gonna ever use it tho.

It ***might*** net you 2-5 FPS or so, but only in games that actively support Physx. I dunno about you, but Nvidia wouldn't be seeing my money just so I could have a 5FPS increace in a select few video games. I would take that $50 and but it towards a very beefy power supply rather than using two.

If God Almighty decided to open up the heavens and drop $300 on me this is what I would do with it.

PhysX takes about 1-2% of my gpu's activity on a GTX280. It's really not a hit at all. Heat effects my nVidia card more than PhysX

As far as my psu's are concerned, I just thought I would try something different. So far, so good.

For me, Physics was brutal. Worse than Chemistry.

Oh that is sooo true!

Binge: How do you measure the %age physix takes on the performance of your card?

Binge · Dec 27, 2008, 06:55 PM

The difference of the (noPhysX)-(PhysX) frame rates in a title divided by the (noPhysX) value. I used Mirror's Edge, Crysis (yes Crysis will take advantage of PhysX), and 3dMark Vantage for my test.

Merry Christmas and a happy new year. I love all you guys. lol
