screen shots still coming if you need them(havent been playing much the last couple days)..
i think maybe this is a null issue anyway mate, me just being picky... i had another look and your right, it is only teleports and terminals... i can EASILY solve the problem by jumping on my big PC... and upon more thinking about it, the impact on performance couldn't be any more than 5-10%, due to the fact that the unneccesary draws compared to normal draws is minimal anyway.
my laptop sees 80m/s a frame, 20fps on low graphs
something like 4 or 5 fps at full graphics...(400-500m/s a frame) but im not drawing terrain on the laptop(not that i can see anyway) so i dare say the REAL result would be lower.
***edit - Resolution difference between 1024, and 1440 is about 3-4fps(minimal) WINE doesn't have too much issue with higher resolutions......
if you ar einterested to see the terrain dissappearing bug - i can still post Screen shots, though i have only reproduced it under WINE, and the same game folder runs perfectly under windows. would like to see those distant teleports/terminals clipped one day though... it put me off first time i played with draw distance i thought nothing had happened.........
