BSP is better for indoor games (rooms)
ABT is better for outdoor areas (large viewing area)
Why, I'm not sure, but there was a large thread about this in this section sometime ago...

Okay, now that's cleared up. But as far as I could tell only a7 pro has BSP. I was thinknig about upgading my A6 com to A7 Com....but it would be taking away BSP from me...is it worth it? Am I gonig to miss BSP and wish I hadn't upgraded, or is ABT in most cases just better anyway?

I can say that the one level I've been tinkering with in A7 slight framerate decrease in ABT only mode (5-10 in one particular section). Keep in mind I'm using old style collision (USE_AABB and enable_polycollision = 0.5) and this doesn't work in this mode. My player will become a ghost and walk through walls, although he doesn't fall through the floor. I don't know if this might have something to do with my framerate drop.
However, when I build in "classic" BSP mode (I have pro), I still get a 2-4 fps drop at that same section. In A6 Commercial, my fps was always 60 and rarely waivered (and never in this particularly level). In A7 Pro, it drops a bit. From what I've read, BSP and ABT work together and it can be "tricky" to get them to work together (according to Doug), so maybe that's the reason. I don't know what the tricky part entails. I've asked a couple of times, but never got a response.

enable_polycollision dosent work? Well, in ABT do we still get poly-percise collisions? Or are we back to bounding boxes?
