if i am using a clip brush, on say somthing like individual stairs on a starway, is it reduntant to also make those steps also func_detail so they aren't included in VVIS calculations?

Clip does not break visleaves. Func detail does not break visleaves. Non func detail stairs will break visleaves,clip or not Must func detail them.

thanks for clearing that up mate, it's nice to have a definitive answer for once on the subject =)
I'm hoping it's this year, that i really get my hands dirty, and learn/understand the vvis process, and to use all the in-game diagnostic tools to tweak the optimization for my maps... it's just so daunting to me and i am a slow learner ='(
I mean, i'm not a complete idiot, i know standard optmisation, i.e., proper skyboxing, visblocking, hints(very simple ones at least), nodrawing, prop fade distance, areaportals, etc etc, BUT i still don't really understand how visleafs are cut and what that really means.

1) skybox 2) func details (3) hints 4) area portals)
1 and 2 are MOST important.
OK visleafs.
Take a box group. now break it down into as few convex volumes as possible... oh wait, it's already one.
now put a sphere in the middle. Now break down what's remaining into as few volumes as possible. there's thousands! (depending on the number of sides of the sphere). make the sphere a func detail, theres back to one visleaf!
world geometry (including water, not including clip, displacements) break up visleafs. entities do not.
