Unable to start due to PhysX
I'm unable to start the game, it pops up with a PhysX Init Error before anything else.
"PhysX init failed. Make sure you have PhysX 2.4.4 drivers installed".
I'm have v9.12.1031, anyone else having this problem ?
I would prefer not to downgrade my PhysX just for this game, then all my other games would suffer.

All are default locations, and version 310.70 Nvidia drivers:

Uninstall - NVIDIA PhysX

Install - PhysX_2.4.4_SystemSoftware - From -
C:\Program Files (x86)\Steam\steamapps\common\Silverfall

Copy - v2.4.4 Folder - From - C:\Program Files (x86)\AGEIA Technologies

To - C:\Program Files (x86)\NVIDIA Corporation\PhysX\Engine

Install - PhysX_9.12.1031_SystemSoftware - From - C:\NVIDIA\DisplayDriver\310.70\Win8_WinVista_Win7_64\English\PhysX

DO NOT Uninstall PhysX_2.4.4_SystemSoftware running the game will cause a forced reinstall

Yea, I fixed this and other games like two worlds by uninstalling physx and installing the one that came with this. Then, I ran the physx installer directly from nvidia's site and it installed new version but kept the older peices that you need. If you install a nvidia driver make sure to unselect physx, otherwise it will uninstall it and then install the new copy which borks it for older games.

This issue should be patched instead of requiring players to keep old bits of old versions of PhysX which could create problems in other applications.

Use Tunngle to play online. I have no problem with it.

Since the developer shut down, not going to happen.

Thank you so much, Agret! Just installing that Legacy drivers worked for me :) A lot easier than uninstalling newer drivers.

Still I have the same prob in win7 (x86). And when i try to instal the PhysX Drivers from here http://www.nvidia.com/object/physx-9.12.1031-legacy-driver.html it took me to the store page!!! Any Suggestions please before we buy these games?

Finally i found my solution. If the Problem is for Tages SA Drivers, go to http://www.tagesprotection.com/main.htm and download the Microsoft® Windows™x86 (32bits): TagesSetup.exe. After i install this driver, the game run perfectly...!!!

That is an issue. If this is the case you should be entitled to a refund if you so wish.

Is there no LAN option in the game? If there is you can play online using Tunngle from http://www.tunngle.net

I think there is an option for a LAN game but I barely started before I saw I had only downloaded the expansion and not the full game.
