The game runs very smooth on my GTX660 and it accepts Mouse and Gamepad simultaneously, which makes the experience quite nice.
There are just two things: 3D is not working. VorpX menue show Z-mode or adaptive mode, but unfortunately the picture stays flat. I tried troubleshooting and resetted the settings in the VorpX-Configuration Menue (which helped with the same issue I had with Oblivion), but on Far Cry 2 it makes no difference.
The other issue: FOV seems a bit to narrow for me. I searched the web but found nothing,what could help here. It seems you can’t change the FOV in game version 1.03 with an ini-tweak. The only thing which helps a bit at the moment is to set VorpX-rendering to Letterbox-format.
