Lol. Well, those round walls are func_lods, so they won't render if your far away anyways. There are a lot of func_lods on the heavier details, and I did spend a lot of time optimizing. Did everything I could think of to optimize short of changing the layout (which is why I like this map in the first place).
Not trying to "lay the burden" on anybody. A lot of people play this map with full video settings and don't even notice a bad framerate. I was just offering advice to those people with slower comps on how to improve their framerate, because a lot of people are clueless when it comes to their computer's performance. I have to run CSS with all my vid settings on low no matter what map I play just to get enough frames to shoot for the head first.
