No, I mean to say that the console controller is really the only way I can play the game on the PC.
With the 360 controller, there is no graphical tearing, no jumping, nothing. All the minigames work fine and the character's movement on screen is fluid.
With mouse and keyboard, none of the above is true for my system.
I am running an Intel Core Duo 3.16 with 4 GB of DDR3 RAM, a nVidia GeForce GTX 275 video card with the most recent drivers, with a machine that have virtually no background programs running while I run games. I can run most games at 1920x1200 resolution with settings up to max with acceptable framerates, including this one, but only with a 360 controller. With a mouse and keyboard, well, even after trying every single .ini fix on this forum, I had no luck. With the controller, it's beautiful.
I've read as much as I can in this forum, and without trying to sound like a troll or a fanboy, I will say this: I like this game, I really do. It's like some of the best parts of Splinter Cell, Mass Effect, and Burn Notice (three of my absolute favorite things) all rolled into one game. I do not like, however, the workaround to make this work on my PC. I own a 360, which is why I had the controller to use, had I known that the PC controls were not functioning as they should be, I would not have purchased the game for the PC, but rather opted for the 360 version. For everyone else, it's a $40-60 attachment of limited utility.
