The only map I would say to no is TTT_Mcdonalds.
It's just a shitty copy from the CSS version.
Plus, theres so many textures, even the best PC's will lag like a bitch on it.
(I tend to get about 30FPS with medium settings on most TTT maps, but on MCdonalds, it dips down to 3FPS on lowest due to it forcing ultra-high texture detail).
All the other ones seem fine though.
