oh, it just made an enormous difference. It went from unplayably slow when looking at the farms from the cave, to only a little choppy right now. My preference is still to use very few trees, since bots see right through em, but you decide how to proceed.

Also FYI, some flags can't be attacked by vehicles RN. The flag pole must be made accessible; if a flag is surrounded by obstacles where there's no wide route to the pole, no matter how wide the cap range, bots don't think they can get there.

thanks for you help
i deleted some trees , tell me if it changed things

Very interesting terrain, i love the way you built up blue's airbase cave, that's really cool. Trees, however, are a big performance problem, even for good computers. For the forests, you should consider making the trees 2-3 times wider and reducing them by 1/2 or by 1/3rd. As for the crops... i counted 600 ish trees used just as farm plants, really do consider replacing all of those with colored mounds of soil or something.
Flag bases need to be built up too, if they aren't between buildings they either need protective hills or walls, but do give them multiple entrances. Some are just too exposed. Think about placing spawnpoints too, blue's airbase has a little fenced off zone that would be perfect for spawning, consider using it, and making similar spawning zones on other flags. Looking forward to seeing this develop.
(and swing by the Ravenfield discord for mapping help. if ya need it!)

Very good map, maybe less grass and trees for potato PC like mine
