Don't give up now, I'm just getting started.

Something topic related, I don't see why he wouldn't test anything from the 8800GT range up to and around the GTS450 range. Those are the cards people usually have laying around and want to do something with.

Heed this....


If BMAC doesn't have GPU accelerated PhysX, then physX is dead.

Just a random thought.

I don't know about you, but just because certain questions are commonly asked doesn't make them useless. I appreciate a good discussion at any given time, no matter what the question may be.

Then make a video of your own and post it.

Call it "This is better than any video Linus has ever done".

35 Posts removed. Do not TROLL. Try again and its just straight up infractions and if you already got one I will double it. GROW UP !
post #78 of 82
Could anyone do the same test but with a amd card as main GPU? I'd like to see if a slow physx card would also bring down the fps and by how much. But don't use a very old card and then the newest cards, I'd say use a card from each generation to get better data.

I agree that he shouldn't have just compared a 4-5 year old card to ones that just came out recently, but I wouldn't hate on him for it (not directed directly at you mbudden, but in general).

How does it compare to letting the cpu do physics? vs using the a single card.

Dead slow, don´t even think about it, not with Mafia 2 anyway.


Did a little test with Mafia 2 benchmark, max out @ 1920x1200

Asrock P67 Extreme 4
i5 2500K @ 4,5GHz
2x2 RipjawsX @ 1600C7
GTX 580
GTX 460

First with the GTX 580 handle the PhysX (single, no other card), then the GTX 460 and then the CPU.


GTX 580 (single, no other card) avg 49,5fps
GTX 580 + GTX 460 avg 53,9fps
GTX 580 + CPU avg28,9fps

GTX 580 usage with the GTX 460 as PhysX was around 75-99% during the session.
GTX 580 usage with the CPU as PhysX was around 25-50% during the session.

Not a pretty sight.
