Sins and Vista?

I recently stumbled upon this game from various gaming websites/forums rabidly raving about how sweet this game is. My only concern, is that about Five-ish months ago I bought a new gaming computer. Unfortunately, I didn't do enough research and am now unhappily stuck with Windows Vista (AKA piece of shista). While things have been getting slightly better due to my use of 3rd party programs like Wlan to stop annoying internet hiccups; most games still have flaws that do not work well on my computer.

Examples:
**TF2 randomly has an error where the driver crashes, but miraculously recovers about a minute later. It's like watching the resurrection! (My drivers are all up to date)
**Universe at War: Randomly crashes when the game starts to get interesting. (Unrelated to number of units, the crash is, completely random.)

My point is this. Both of these games are part of the new cute line of "Games for Windows!" However it is in my honest opinion that the line should read "Games for Windows XP Service Pack 2."

So, developers. I have a Geforce 8500gt graphics card, 4 gigabytes of memory, over 500 GB of disk space and a sincere will to try your game. My question to you is this: Is your game Vista friendly or should I avoid this game too?

Ps. I read you're coming out with a demo soon.. interesting! Perhaps I will wait and see how well that runs on my machine before deciding to purchase. Time-i
