first let me say this game is fantastic... im sure we all know that, now on to the problems:
my controls are lagging about 1/4 second. walking to the edge of cliffs is almost impossible without running right off the edge. wall jumps are impossible to time correctly, it involves pressing jump just before hitting a wall, otherwise you will slide off the wall while repeatedly hitting jump and not jumping.
i spent a couple hours playing the 360 emulator game, and my gamepad is still quirky and gets stuck running full left a lot, i give up on the gamepad, its clear without a real live 360 controller you just arent meant to be controlling this guy with a gamepad... but the lag is occuring even with a keyboard. ive tried a lagfix found on the steam forums, ive tried reducing resolution, ive tried windowed mode, ive tried re-installing, ive tried both the DRM free humble bundle version, and the steam version (since the bundle gives you steam codes also) and still have the lag. all my other, much more graphically intense, games do not have this problem, even my other 360 ports (such as bastion) using 360 controller emulators do not do this. sad meat

anyone have any suggestions i mightve missed?
