[OUT OF DATE]How To: Run PhysX in Windows 7 with ATi Cards - Page 106

Well, I can only say from personal limited experience. With Quad-Fire 2x 6990s so far tested with GTX465, 480 and 580. The real performance hit is for these 2 titles, Batman AA and Mafia II with a GTX465 + Quad. It's only logical to have a fast PhysX card to pair up with a fast multi-GPU setup (most will disagree, not sure if from their own eperiences or just opinions).

This is recent discussion and take a look if you want http://www.overclock.net/graphics-ca...l#post15377160

Oh and Welcome to OCN!

Thank you StormXLR and Ken1649 for the input. I was afraid that would be the answer. I am trying to get prep'd for Batman AC, but man I hate to spend $150+ just for a handful of particle effects on a handful of titles. That said, I also have a hard time playing a game knowing that I am not getting the full experience. Decisions, decisions....

Hey man, you should feel lucky cause I registered to reply for ya

A couple months ago I was doing the same as you, trying to decide how much to spend on a dedicated physx card.

My system:

Gigabye board - Ga-890fxa-Ud7
Phenom II X6 1100t clocked @ 3.9ghz 8gb gskill 1600 c7
Patriot Wildfire 256gb Sata III SSD + storage drives
Hd 5970 + Hd 5870 both clocked at 900 / 1200

I read through this forum a lot and various others online and articles galore. I read a lot on the subject. A lot of ppl say older gen nvidia cards are fine for dedicated physx. 8800gt or higher I saw a lot. I however wanted to go newest gen but not go crazy on the price and also was looking for single slot card so I settled on a single slot GTS 450.

There was some hassle getting it to play right with the system / amd cards n what not but not too bad. I played around with it in and out to see the difference it made first hand. Alice Madness Returns was a good game to refer to as it played pretty bad with physx set anywhere higher then low without the nvidia card. Sad really, 6 core cpu and 3 gpu and still. But yea, the whole physx code written to only work well on nvidia hardware thing. So yea, with the GTS 450 in and set as dedicated physx card Alice played great with physx set to high and all settings maxed at 1080p.

I did the same with a couple other games, Batman AA for example, had the same results. I would have to turn AA down without the nvidia card to get the frame rate up. With the 450 in and running Batman plays ridiculously better with all settings maxed.

Also you've got the newer gen Amd cards obviously so I would think you could see even better results or just similar but in my case it worked out quite well and am happy to stick with my 5000 series cards for now and wait till 7000's probably and skip 6000s. Though I do have a Hd 6970 in my htpc. Overkill for htpc but I use it to drive 3d on my hdtv and also as a 2nd gaming pc.

Hope that helps man, If I were you I would get a 450 and see how it works out for you, or go bigger and more expensive if you want but in my case I found it not necessary. Also I picked the 450 over the models cheaper then it because of the nice jump in specs of the card.

I agree to go for a minimum 450 to match 2x 6970s in crossfire. A 450 (192 cuda cores) will have twice the performance of a 430 (96 cuda cores).

You can overwrite the existing driver/PhysX SS without uninstall.

1. Install Forceware 285.xx (do not restart).

2. Install PhysX SS 9.11.0621 (do not restart).

3. Run the 1.055ff Patch (restart PC).

Done.

PhysX-mod-1.05ff.zip 42k .zip file

Thank you everyone for the insight. You all told me exactly what I expected. What is unfortunate is that in order to use GTS 450 I would need a new case. I have everything squeezed into a mid tower as I use it in my living room on my plasma/projector. I have no way of squeezing a dual slot PCI-E card into the third slot without either moving the power supply or going to a larger case. I guess I am just going to have to forgo the PhysX until I decide what to do about my case.

Thanks again!

Oh there is a single slot 450 that might fit into the case http://www.newegg.com/Product/Produc...82E16814187131

Here is some feedback
So I got my Zotac GTS 450 512mb for 94 USD
Installed it, booted up my pc installed latest drivers WHQL 285.62, ran the physX mod, restarted the pc , as easy as pie!
Now to Games!
First thing first, I played Mafia II on all max settings including PhysX... It ran at 60 FPS at all times and never once went below 50. Every piece of hardware at stock settings.
I will try post some actual Benchmarks some time later.
Anyone can suggest a good PhysX benching tool?

Yea, download Fluidmark 1.3.1. Make sure to delete all "physx***.dll" from the install folder then you are set.
