Can anyone confirm that physx at either medium or high settings is being offloaded to the CPU and this link is indeed a work around to improve performance?
You sure you just didn't have PhysX at all by doing this?To answer my own question, I have confirmed that without a simple fix the game will offload gpu-accelerated physx effects onto the CPU.
You must uninstall your current physx version, then under C: \Program Files (x86)\Steam\steamapps\common\mafia ii - public demo\3rd, install the version of physx there.
On my gtx260 216, with physx on medium, my average frame rate went up from 23 to 30 by doing this.

I will try this next, I can confirm physx was on the cpu with these benches as per the physx overlay indicator

No, I meant the reason why you had a better score was that the game was running without PhysX support at all once you removed it. How do you know it's using what's in the Mafia directory?If you read over my instructions, you would have seen that I had to uninstall physx and then reinstall the version in the Mafia II directory. How could I not have physx but but be able to uninstall it? Thanks, but yes I'm sure I am correct and I am also sure that this fix works.
what res.?
The core on this 4890 has a bit of legs on it. I'll take it up a bit and see what core, memory or core + memory overclocks bring. The 955 can also hit a higher OC so I might try that as well.
Not sure if you are doing this but you will get better performance if you set one of your GPU's to be a dedicated physx card.
I just ran it and received a B rating...
1920x1200 High with AA on, no Phyx
i7-860 stock and a single 5870 (today I should be fixing that back to what it belongs when I finish my new case and throw everything underwater)
high: 160
min: 7.2
average: 75
Those scores seem like they should be higher. You are running a high res, but still SLI 480s can pump out some power. You don't take very much of a hit with Physx medium to high though, that is nice.Thanks for the fix! It worked and offloaded the physx to gpu here are some scores without a dedicated card. Everything max 16AF and AA on, vsync off.
One thing of note, it looks to me like AA does not actually work, or is limited to only certain objects, as I see crawling and jaggies. Also you cannot select an AA level, it's AA on or off.
I noticed there is already a profile for this game in the NV control panel, I will try enabling that to see if affects performance.

Got to say the minimum and max scores seem to be totally subject to randomness.
I will bench again with a card dedicated to physx.

Which files go in the Mafia directory?
here is what fraps shows me when I record 60 sec @1600x1200. My minimums are not bad. I don't know where its getting 6 fps minimum? Mabe in the very, very beginning?

The fire scenes kill my fps.
hrm... should I put the 8800GTX in my system for PHYSx to supplement the 480? Just wondering if it's a huge difference, and how noticeable is it.... I know it calls for the GT 240, and the best I can do is a 8800GTX... SHould I just go out and buy a GT240?
or maybe go on ebay and buy a PPU for 40 bucks? are the NVIDIA cards better at handling physx than the actual device itself? I have 1 PCI slot, that's unused...
