If 32bit works for you, So, what's is the problem then?
Name your processor, Windows x32 or x64 are in use? and the amount of RAM installed of course.
in running x32, interface is fine but almost every delay 0.1~0.3 second and sometimes little dropped frames in scene
in running x64, same problem x64 is little dropped frame in scene too but hella delay interface only
background system is not lag. this game is lag only
Processor Intel Pentium CPU N4200 @ 1.10GHz, x64, 4GB RAM.
Ok, I see.
Unfortunately, I don't know how to help you, but it probably has something to do with using an Integrated GPU.
Last time one person also wrote about delays, and he also said that he didn't have a discrete graphics card, so the game is probably just not optimized to run on PC, with integrated graphics.
