How to enable hardware PhysX processing?

[Enterprise2448]

After running the techdemo at about 22 fps and the game itself at merely 12 or so, I came wondering if the PhysX work is being done by my CPU or GPU. Where can I set it to be done with GPU? I am using 8800GT, afaik it is PhysX capable.

Great game btw. Superb infact, can't wait for english release. Although I am having trouble running the game with SM 2.0 or 3.0, the textures are just missing everywhere.

Game slower then tech demo, because in tech demo lot of game calculations is disabled.
Try to lower texture and normalmap quality.

8800 GT is a bit old to run this game using all its features, specially at higher resolutions.

The game goes to 10-12 fps in some parts if you use high resolution in this range of cards. A little better, 20 fps at lower resolutions. The physics are active in the Nvidia control panel, and only works with SM 4.0.

With the latest drivers from Nvidia - 180.84 at least - the game has bugs in the textures on SM 3.0, but run fine with older drivers - i believe taht 180.48 work fine with SM 3.0 -. My advice is to use SM 3.0, the game runs a 50% or more better, and see the physics in the demo or the game with SM 4.0 , after passing a level.

Normal fps in-game for me is 15-20 :P

When I´m in non-icy/frosty places 30-40 fps.
