No, I used up my free 30 days earlier this year. The program compiled (while
finding a few bugs, actually!) but ran about 30% *slower* than before. I didn't
find it worth use the remaining days to try to find out exactly *why*, so I
don't know how much it could have been tweaked.

It was mostly 3 years worth of collected bug fixes and some Win2K adjustments. I
believe the MS compiler team is putting most of their efforts on the .NET shit
instead. Probably not of much use to chess programmers. :-(
