@Polonia it turns out we have a bug in the GPU check that hits systems like yours that say
Windows 7 Professional, 32-bit (Service Pack 1)
That is, our GPU check works okay on Windows 7 or 8 64-bit as it looks for nvd3dumx.dll, but not 32-bit (nvd3dum.dll). We'll have this check fixed in a future release.
However, there is a problem with your setup. The Pentium Dual T3200 is a Merom-based CPU, and does not meet our minimum requirement of a Core i3 or better. You can continue running this, but don't expect the greatest performance or reliability with the service or apps on Airspace Home.
@turmewr3ck and @xAmirKatzx : By any chance are you also running a 32-bit version of Windows? If so, it's fine to click "Ignore" for the GPU check until we fix this.
Regarding whether your graphics cards and graphics drivers are up to par: @xAmirKatzx, the GeForce GTS 450 is good enough to run most Airspace applications well. @turmewr3ck and @Polonia you may be somewhat limited with 256 MB of VRAM and GPUs based on the G92 architecture. Orientation tends to be more draining on those cards, but many of the apps in Airspace that run on the Unity engine should be fine.
