Glad to see that you're also working on this older map again. Cool map, too
The biggest problem for me is still the mid area. I've lots of troubles with lags there, I don't have on other maps with around 3.000-4.500 wpoly. I'm not sure why, it's the same with the ice mid of prolandr (around 500 wpoly). Maybe it's a problem with my old pc. Normally I play with around 30 FPS on most of the maps. In the mid of this map I've around 12-16 FPS with reflectivewater and around 18-22 FPS without reflectivewater.
The improvements I could figure out are very nice and helpful.
Most of the plank textures are still misaligned. Might be easier to use a different texture for the single boards like jitspoe already mentioned.
I'm wondered, that no one mentioned before, that the barrels are too big. So the alignment of the top and bottom textures doesn't really fit.
If you climb up the ladder between the flags too slow, you can get blocked at the top of it. Would be cool if you could add a ladder clip brush there.
