howdy Zub,

you should definitely have the graphic detail set to medium or low (i have it on low). i have a macro for it to just make sure.

you should also make sure all regions use the same game resolution and the same width:height ratio. this improves performance and the quality of image (correct aspect ratio ftw)

as for what dimensions and whether or not you must auto-hide the bar.. that's up to you. you'll have to do the math and figure out the resolutions for all the regions, the trick being to keep them all the same aspect ratio.

as for maxfpsbk and maxfps.. i'm not sure. it definitely, 100%, helps on the performance of overall game play.. no doubt. but i wonder if the pip swap is slower the lower your maxfpsbk. as if it only gets to do part of the scaling transform per slice... less slices per second means it would take the same number of slices... just longer clock time.

i'm now on a quad core w/ 2x 260s. pip swap is about 0.5-1.0 seconds so far. i have found times when my fps would drop on my main for no apparent reason... but i'm still chalking this up to vista64 flakiness.

keep me posted if you find any other useful tricks.
