If you use Vista 32 bit you can only use 3.5 Gigs of RAM. If you want to use more you have to use Vista 64 Bit. The problem comes around here, apparantly there is a teething bug that comes around the corner when using certain DMA devices and Nvidia is a big problem in it.
Microsoft released a patch that people can download here:

Another thing people need to be aware of is that you use the X-FI Soundblaster cards there is a new update out that you can download that fixes "issues" with Vista X64 i am not aware of what.
Another update was also released that fixes Bugs in your Videocard concerning memory usage.

Result for me is that Vista runs except occasionally it just won't boot up until i restarted a few times and then its fine again. And sometimes my Bios complains about a Hypertransport flood during a boot. So I think my AMD processor might need a driver or its a piece of junk. Cannot wait till the Phenom is out ;)
On game development news:
I have programmed a small application that can read files and pack them Right now im spending most of my time making a DirectX9 engine with Easilyconfused for the Beyond the redline BSG mod hopefully this will be dragged to the firefly engine. The goal is to use DirectX10 aswell but considering my issues with Vista right now i am going to spend most of my time doing the things that dont require vista :)
Its great to be done with my bachelor!
