Do you use a dedicated Physx card?

I have had my fun for the day. I'm curious to see how this works.

Has anyone had any great impact using a dedicated PhysX card here?













Edit: That may be hard to see. I am trying out a dual gpu card as a dedicated PhysX card. Lets hope I don't break anything.

Sometimes when you have a really good GPU you can get better performance by letting it do everything, than having a weaker one for PhysX. And since you already have 2 Titans, that might be the case. Just do benchmarks with and without the dedicated card and see what happens.

Daym thats overkill. I don't think is worth the extra resource and effort for physx card though. I rather a more powerful gpu like yours and just run it. Sell the physx card and spend it on something nice.

It might be kinda hard to sell a GTX 690. I may just build a "1080p" machine once I finish my CPU and motherboard upgrade.

I'm just having fun with it really. I got a 159 point increase on the 3D Mark Fire Strike benchmark at stock CPU clocks.

I have read mixed things on dedicated PhysX cards on the web and was wondering if anyone here had any good or bad luck with them.

i have an old 280gtx, i should toss it in someday and do some tests. It can do physx i think. But thats all i got, i don't burn through money buying thousand dollar video cards every 12 months.

Your using a titan, so i doubt it needs it. but who knows, maybe for some games it does help reduce stress. You should test it out and see. I don't have any physx games that run below 60 fps so i wouldn't likely bother doing it even if it did help slightly. I'd likely run a power meter on my pc before and after to see the wattage use... if its more then 20watts on idle theres no chance i'd kept that card in there. But your rich and have no common sense by the looks of it since you have a 690 and two titans, so wasting money on hydro means nothing probably for you.

No common sense? That's not very nice.
I bought the 690 2 years ago and now 2gb of vram doesn't cut it at 1440p. Besides, I'm a tech/gaming enthusiast so this is what I do for fun. Some people spend thousands tuning their car. Others collect guns or are sneaker heads. There is nothing wrong with spending money on things you enjoy.

Back on topic. Throw that 280 in and see what it does for you. Folks on other forums say it works quite well.

@GoldenElementXL: sorry bout that, when you put it that way it does make sense. people probably spend many thousands more on car upgrades each year.

I'll test the 280 sometime and see how much power it uses and if it helps fps at all.

Jokes aside, I doubt you can use dual GPU as a dedicated PhysX card. I think it will recognise only the one GPU so you will have a lower clocked GTX680.

But I can't remember where I saw benchies and read that today's GPUs are powerful enough to emulate PhysX wihtout taking a noticeable performance hit.

You can try this on a game with PhysX and post the results :D. (a test with PhysX on with the two Titan black and a test with PhysX on and two Titan black with GTX690 as dedicated.)

ps: try to sell the GTX690 for around $400 and you will see many people willingly to buy it.

ps2: Corsair Axi 1200 as PSU? :P

@Coseniath:

You are correct. Only 1 of the 690's gpu's can be used as a dedicated PhysX card.


Here is Batman Arkham Origins

The first bench is WITH the 690 as dedicated PhysX card. Everything maxed at 1440p
The second is without.

(sorry for the blurry pic. I used fraps to capture the screenshot and hitting any key closes the benchmark)

:O

This is 15% increase. Nice. Well you can successfully use it as a dedicated PhysX.

Although a $230 GTX760 (maybe even a lesser GPU...) would do the same job.. :P

I do, but that's because my primary video card is an AMD 7990. Eyefinity plus hybrid PhysX rocks.

No ... But I want to .

I have a GTX 560 Ti and an 8600 GT. But, nah. I'm fine with the primary video card.

Woah, it's possible? What drivers do you use?

@fend_oblivion: It's a bit tricky. Google "hybrid physx" for instructions on how to get it to work. Exact steps vary by OS.

That's a nice increase. Have you tried with something that uses PhysX in larger amounts like Borderlands 2?
