What are the minimum specs?
We have not yet completed testing. A non-netburst single core CPU above 3.0GHz with SSE2 would work, but a dual core 2.0GHz CPU would be better. 2GB RAM and either nVidia GeForce 8600 or ATI Radeon x1000 Series with 512MB video RAM will be required to take advantage of some features. rFactor 2 will not run on Windows 98, but will run on Microsoft Windows XP, XP 64bit, Vista and 7.
