Thinking of picking it up on Steam. Are there any issues I should know about? I'm assuming 360 pad support is included?

Dead Rising 2 has it so yeah, seems likely.

I've been enjoying it. Gamepad support is there since its a GFWL title, and it's pretty much Dead Rising 2.

Cool. I'm assuming it runs well also? Any performance issues or should I be waiting for patches?

Xbox360 Controller support is perfect, as it was in 2. Runs exactly as it did in 2. The only setting you might want to turn off is blur which should give you a huge framerate boost. It isn't a terribly demanding game but check the minimum and recommended specs to be sure.

Also, Achievements.

Are there any console ports that don't support the X360 controller? I don't think there are any.

I actually have a bit slower framerate on OTR, but the difference is mostly negligible.

I've been watching cutscenes on youtube of what i presume is the pc version and i swear the pc version looks SOOO much better than my 360 version. Framerate, lighting, just everything looks way better.
