[OUT OF DATE]How To: Run PhysX in Windows 7 with ATi Cards - Page 116

post #1151 of 1230
I followed all the above and there were no hicups. I have enabled physx from the nvidia control panel and gpuz shows physx as enabled but I don't get any load on my second 4870x2 gpu core and on my physx card.

Is physx actually running I wonder?

Also how would I go about overcloking it, I have MSI afterburner installed which I used on my 4870x2 previously, but when I select the GTX 260 and change its values it does not have any effect on the stability programme in GPU-Tool.

In your first screenshot, you'll notice towards the top that it says CPU PhysX next to your score. This is because FluidMark still doesn't know that your 260 is there. To get around this, you'll need to go into its program files and find the PhysXDevice.dll and delete it (or rename it). This will make the program look to the drivers to figure out what card to use and the hacked drivers will it that there's a GTX260 present. smile.gif

In most PhysX-enabled games, you'll need to do the same (find the PhysXDevice.dll file and remove), but in the case of Metro2033 it doesn't have one and PhysX worked for me by default after installing the patch and drivers, like you did. Like I mentioned earlier, the PhysX in Metro is very low, and it won't give you much usage on your card, but it should still be there.

Strange that it isn't using your second GPU on the 4870x2 though, was it working before?

thanks for that see updated scores.

my second gpu in fluidmark doesn't run but now the gtx260 shows a maximum of 13% activity. Running games and the metro 2033 benchmark for example the 4870x2 gpu's both show usage.

ALso is it normal for the gtx260 to show minimal activity in games and in benchmarks as I am not getting very high loads?

If its running smoothly in Fluidmark, then its working. And I think low activity is normal. I get similarly low usage with my 460, and I thought it was because it might be overpowered for PhysX, but it may just be a general thing. Maybe someone else can post and confirm this?

I'm not sure about FluidMark not using the second GPU, but if its working in games then I wouldn't worry about it. thumb.gif

I have a 7300LE laying around. Can this be used for physx? Is it too old?

Cheers mate that good news. I'll try and get a confirmation from another website that was linked to the p5q owners club in the meanwhile. thumb.gif

I don't think so, I couldn't find it on the supported GPU page from Nvidia. I think it only works with 8800-series cards and later.

I didn't know this was doable, but it's great news! thumb.gif
I have a HD7970, but was kinda bummed that I wouldn't get to play Batman AC with PhysX effects. Now this might happen.

I remembered I have a "ASUS EN9600GT Silent" in my old computer. It seems to support PhysX (it's on the "Supported GPU"-page from Nvidia). I've read a few older posts in this thread mentioning the 9600GT and it not being powerful enough, but this test seems to indicate that it might be. Anyone had any luck with this card?

Edit: Seems like the 9600GT will bottleneck my HD7970 so much that it's probably not worth it. Well, no PhysX for me.

Now that I'm home, I ran the Fluidmark 1080 bench myself to compare. 6970 usage was in the mid-80%, while GTX460 got up to mid-50%.

550

I'm wondering if your 4870x2 is bottlenecking your PhysX maybe? Because when I ran the 720 bench, 6970 usage was around the mid-60%, while GTX460 was right at 70%.

Also, something I thought about considering the second GPU not working is that Crossfire doesn't enable if the application isn't in fullscreen mode, so that may be the issue there.

I'm thinking you might be right, but it still might be worth it if you already have it and want the additional effects. Its up to you, although you can run almost all of the Batman PhysX effects on CPU, so if you have a fast enough CPU you should be fine.

I believe if the game doesn't detect a PhysX GPU, it limits you to the medium and low PhysX settings, with High only available for cards (at least in Batman: AC).

Only FluidMark 1.3.1 supports muti-GPU.
