Ahhhh, ok. I've actually been emailing with a guy at Immersaview on this very subject. Enlighten me, what's the difference between pre-warping and spherical distortion correction? I thought you could just reverse-pin-cushion the whole image and get the correct shape.

I need to look closer!

I didn't know about the stretching issue. The TH2Go is still a tempting option, but I don't think I want to pile all my rendering onto a single PC, even if X-Plane didn't have stretching issues. The huge advantage I see to the TH2Go is that it allows the use of pretty much any game or sim, even those that do not directly support multiple displays. I'm pretty much going to be using nothing but X-Plane....although driving an F1 racer from the front of a Learjet cockpit would be rather amusing. :)

Actually the AS350 sim I flew last week has 8 projectors, and they are using a dedicated PC for *every single one*. Frame rate is just so critical in these applications, and our sims can bring just about any computer to its knees with high resolutions and detail settings. Granted that sim is 2009 technology, but I don't think our hardware has advanced enough to overwhelm the demands of a flight simulator. I figure I need all the processing power I can get, so I might as well use one PC per screen.
