That's interesting. Ive been running a 2 monitor set up on Vista 64 Ultimate for some time now and my C:\Users\Lew\AppData\Local\VirtualStore folder is empty and my setup runs just fine.
Here's a comparison.

The numbers sure do make it look worth it. Although my TrackIR 4 Pro w/ trackclip pro works just fine I might have to buy this.
Finally showed up at my local Best Buy. Now, I've purchased the Russian download version, English download version and the English DVD version. Glad to support the devs.
I've downloaded it and will give it a go over the next 2 days. I'm off from work and there is an 8-14" snowfall headed our way tonight so I'm not going anywhere.
Reading some of the earlier posts I see you need pics of the sun shaders. I have a few more I'll post later tonight. Particular image size you want? I can also furnish the original Canon RAW files if nesc.
