Kingdom hearts 1 - new map/cutscene lag.2

[refraction]

You mean the lines that appear? That is an artefact as a result of upscaling, there is possibly one of the hw hacks in gsdx to solve it (maybe one of the sprite/alignment hacks) but I couldn't tell you because I'm not sure

[scythefwd]

is your D drive a separate physical drive? If so, it should actually access that data faster, as it doesnt have to run pcsx2 as well from that drive (read head can only do so much at one time)
