I think that depends on what you mean by better. I wouldn't say that it runs better on my E1705, but it is much much easier to play with a mouse and keyboard. My bro has it on Xbox, and I couldn't get the ducking thing to work right. Was weird for me. On the Pc, I can do it all with no problem, plus the little helper on the HUD is nice. So far I have ran it at 1024, 1280 and 1920. At 1024 I can run everything at medium and get between 20 and 60fps, averaging about 40. At 1280, everything medium, it runs between 10 and 40fps, averaging around 25, set on low, it runs about the same. At 1920, its almost unplayable unless everything is on low, really a shame. I wanted to see what some of these newer games look like on a 133dpi screen.
All and all, I love the game, the whole reason I bought it is because I loved the Xbox version.
