Benchmark test: please look at this

No slowdown anywhere, even with Firefox running in the background.

Windows Vista erm.. Home Basic, build 6002 (apparently)
2.2GHz Intel processor (not sure which of the range)
3GB RAM
Bog standard intel GFX-card (Mobile Intel 4 Series, if that means anything)

I can give feedback from my own rig tomorrow evening but, if this thing runs it with no trouble, mine's gonna breeze through.
Just for the record;

AMD Athlon 4000+
3GB RAM
Cheap-and-cheerful Nvidia card with 1GB V-RAM


I know this isn't very precise, but hopefully it's of some use to you 

I was just planning to just edit it into my first post when I got KS working on Linux, but the turnout was so different this time would be justified to make a second post.

In Ubuntu, it is really bad.  Juni moves really choppy, and on the transition to the second room, I first see a bunch of red dots (the tiles under the objects, I guess?) for about a full second.  If I press Ctrl+R, Juni's death animation takes about 21 seconds.  *gasp*

I'm really surprised, because the computer had no problem with this level in Windows, and other levels that I would expect to lag are running fine in Ubuntu.

Red dots are the image that appears while COs are loading.
