I have taken an FPS hit when playing near the new trees so was changing the max texture from 512 to 256 to see if it would help. (it did not)
However I then lost my default desk top and game resolution which was 1280 x 1024 to then become 1280 x 960 (game) and 800 x 600 (desk top).
I reset my desk top then went back to game to find this option was not available and i could only choose 1280 x 960 or 7??. Producing a squashed up view.
I have since edited the video file to 1024 and all is OK.
I think.
I do note the odd very thin grey line thru the terrain where I assume tiles join.
FPS is good unless I am flying close to and looking at trees. Where upon it can dive from 45 to 12! Presently if my opponent dives for the trees I am forced to bug out.
