PhysX question

[niggles]

***edited***
So I have an AMD 6950 as my primary GPU and I have Batman Arkham City and wanted to run PhysX. I have an old GTX275 (used to say GTX670, but that was incorrect) and was thinking of throwing it into my Asus Maximus Gene III so I could run PhysX... but will that even work? Can I run an AMD card and a Nvidia on the same board and use the secondary for PhysX?

Wait...

You run a 6950 but have an "old" GTX 670?

You can run physx with AMD cards but you need hacked drivers. I don't have any links but maybe someone else knows them. Otherwise google will find it.

Would an 8800GT be good enough for some hybrid PhysX? Or would something more powerful be needed.

an 8800gt is fine. I ran physx with a 9600gt for a while which is much slower.

If I have a GTX 670 I would run that and throw away the 6950

Download latest Nvidia drivers to your desktop
Uninstall AMD drivers
Shutdown
Remove 6950
Install GTX670
Startup
Double Click the Nvidia driver and install.
You have PhysX in Batman AC.

He/she probably meant GTX470.

OP, a GTX670 is a faster card than a 6950. Did you actually mean GTX670 or something else?

 

[niggles]

I honestly meant GTX275, I have no idea why I typed 670... I recall thinking when I bought the 6950 that I *wanted* a 670, but the price diff was too great... anyway, I think this answers my question... Yes, I can run a hybrid, but it looks like a right pain in the arse, get the right Nvidia driver, find a hack. I'm looking through this now, but it really seems like a pain in the arse. Still, I really want to run PhysX

As for unloading the AMD drivers, the last time I did that and rebooted I couldn't see almost anything AMD have serious messed up drivers and it was almost entirely black anywhere that colour was supposed to be. I'm going to stick with Nvidia from here on out regardless of price.

 

[niggles]

ok, I have a further question, has anyone done this? It's not clear to me at what point I'm dropping the card in, is that before or after I've installed the nvidia drivers. Does dropping the card in before teh drivers screw anything up? if the card goes in after the drivers should teh patch also go in before I put the card in? I guess I'm just concerned with screwing things up if the card is detected and it doesn't have all the crap it needs... also will the nvidia drivers lock-out physX if there is no Nvidia card present? so confused...

 

[cmdrdredd]

The card needs to be installed for the drivers to find a compatible card.

Never heard of that issue before. I have uninstalled and reinstalled drivers from both camps and have never had something like that happen.

As for the order in which you put the card in, follow the guide. I dont know if you will be able to install a driver without the card there though.

an 8800gt is fine. I ran physx with a 9600gt for a while which is much slower.

I don't think the 8800 GT suffices anymore and can actually drag performance down. Unfortunately I don't have a source I just ran into some testing while getting owned by physx in BL2 and it was clear that cards less then some point will only slow down the overall FPS. I can't remember the point but I believe it was greater then the gt 8xxx series. (some lower gtx 5xx card iirc)

Google it for more clarity, but it was interesting that a weak physx card was worse then no secondary physx card.

That was something strange, I've installed/uninstalled countless drivers from both companies and switched cards etc. and never had that problem.

I have been considering doing the same with my old 9800GT, just for fun. There are two problems however: (1) I am not sure if that old card is strong enough and (2) there is not a single PhysX game that I want to play. But I might do it anyway.

Never had such a problem with either brand. What is strange is that you blame the drivers, which you uninstalled, so you are saying that something you do not use is causing the problem? By that logic it could be anything imaginable...

I hadn't had it happen up until this 6950, and I've owned a sea of ATI cards before this. I spent ages trying to get windows into some kind of safe mode so I could install the drivers back in. I haven't uninstalled the AMD drivers on this card since.

I used to do it with my old 8800GTX as a secondary to my 275GTX, worked very well. As for not having a game to play it on, I just picked up Batman Arkham City, and after seeing what Arkham Asylum looked like with and with out PhysX I was totally sold.

OK, I'll drop the card in, then install the drivers, then the patch, and cross my fingers that it doesn't kill PhysX when the ATI card is detected. Thanks everyone.

 

[niggles]

aaaand, that's a bust, I can't find a reliable place to find the old Nvidia drivers that actually work with this hybrid patch. The last set of drivers that worked were 9.11.0621... oh well, it was a nice idea, right?

This is a thread about either using zero physx with an AMD card or getting the hacked drivers to work for physx with an old Nvidia card. Either way, the card the OP has is faster than either the before mentioned cards.

Nvidia driver 285.62 available from here. This works with the mod.

I was just mentioning it for clarity. At some point a slow physx card slows down the FPS, and older ones don't do or hardly do anything. (can't remember source(s))

 

[cmdrdredd]

I used a 9600gt which is slower than an 8800gt and the framerates were fine.

 

[wand3r3r]

Did you do any empirical testing to see if the framerates dropped on account of the 9600 gt, or if you gained any fps?

There is a possibility your fps drop, stay the same, or increase, but you will need electricity and running an older high end card with high power consumption would literally be a waste of money. It's not as simple as dropping in any nvidia card and instant gain.

Some people will see this differently if the physx effects are enough to justify or not, but in the end if you have e.g. a gtx 6xx card and throw in a 9x00 gt and lose fps vs. running physx in the 6xx card you are only losing out overall plus you have to pay extra electricity costs for the performance loss.


Personally I don't care if you use it on an old weak card, I just want to relay what I ran into when looking into secondary physx cards as this was news to me and I'd guess most people don't know about it.

what does that even mean though? that is like saying I used a core 2 quad and gts450 and framerates were fine for a certain game. does that mean there is not a much better or more efficient setup though?

 

[cmdrdredd]

It's not that hard people. If you wanted to turn on physx you either do it on the CPU and run at very low fps, or you pop in a card you might have laying around and framerates went up and the game was playable.

You don't consider this if FPS is priority #1 at all.


Noboby here is talking about running a GTX670 with a second physx card. That's retarded since the 670 by itself is faster doing both. We are talking about getting the extra effects, not increasing FPS which is stupid to even say since Physx drops FPS. The difference is a 9600GT is multiple times faster than running it on the CPU.

you are a bit off there. a 9600gt is actually no better than running both graphics and physx on higher end card and could in fact be slower in some cases. and a 9600gt is little to no better at handling physx than a sandy bridge cpu in newer builds that are much more cpu friendly. and if you do have a high end card you can still get a fast mid range card to handle physx to keep framerates higher.
