When I first downloaded and installed .95, my installation of XP was about 4 months old. Except for the disappearing terrain issue (which, at least in my particular instance, I was able to fix) Sylphis ran great.

Unfortunately, that 4-month old installation of XP was quite... furgled... so I did a fresh install. (Furgled, meaning Start Menu items would just disappear, drives would go away --nasty stuff.)

I just downloaded .95 release --the binary, considering I haven't Visual Studio 2003- and ran it using sylphis.exe -map maptest.cmap. Everything loaded just fine, but if I'm not pointing the camera in exactly the right direction (just a tad past 90 degrees to the right from the initial orientation), the terrain isn't visible. It's only a small (45 degrees or so) field of view where the terrain is visible. Looking down too far causes the terrain to disappear as well.
