I have FSX running under Windows 7 with Oculus Rift and it is great. Had no problems in getting it going at all. Some fiddly things need to be fixed but they are minor,
Just purchase the Pagnian motion simulator which works a treat with FSX native. When using the motion sim with FSX and FlyInside, FSX crashes at the last point of loading.
Has anyone seen this before and if so do you have a fix for it.
