-  terrain scene. Reason completely mysterious. Happend twice so far.
+  Mysterious and serious (sometimes bluescreen) crashes due to an error in the
+  nVidia display driver (nv4_disp.dll). Occur with the following combination:
+  Direct3D Render Manager + terrain rendering with OCM or KTE + 
+  hardware occlusion culling enabled (CHC, possibly also SWC) + demo playback.
+  Not tested on other hardware (e.g. ATI cards). Not exactly repeatable,
+  crashes in different places during playback or not at all.
