Woohoo! The demo for the much-anticipated enhanced PC version of DMC4 is now available for download. Download it here. I'll post my impressions after I've downloaded and played it. It should be obvious, but I'll mention it anyway: You will want a gamepad for this game. I use a wired Xbox 360 controller that plugs right into my USB port on my PC.

Good things come to those who wait as PC owners will benefit from having more modes and more visual customisation options to help enhance their demon-slaying action. Turbo mode will turn up the action to insane speeds, while Legendary Dark Knight Mode will harness advanced PC processing power and fill the screen with an unbelievable number of enemies for extra difficulty. Moreover, familiar enemies from the console versions will show-up in new locations in the PC version. The high resolution screen settings allow the cut scenes of the game to run at up to 120 frames per second (up from 30 frames per second in the console version of the game). Slider options are available to manage various visual effects seen throughout the game. Devil May Cry 4 for the PC will have both DirectX 9 and DirectX 10 modes and will also be compliant with the Games For Windows program.
