Played a slightly older film I had, worked fine, only my P-40E had a DT on it the entire time (I had dropped it before filming). Ran another older film of me in a Fw190A8, and I was in combat so I'm pretty sure I'd have dropped that DT as well, but it showed as in place also.
Secondly, on several films with water, it takes a LONG time for the water to display. Almost 4 minutes or so. I don't know why. On some there's a pause where the land mass won't show up for about 30-60 seconds, but I have an FSO film where we took off of a CV and it's totally white (no textures). It ended up filling in eventually but it took forever.
Again, these are films from before the terrain updates, so probably just a compatibility issue.
