Thanks, the main issue with interaction points is physics now. Processing more than a few collision objects / pickups really kills performance on lower-end devices. Looking into GPU-based physics, BSP trees.
This feels much better. That looks like a weapon upgrade. Cool. I've felt the rooms were sparsely populated with interaction points. Might be interesting to have something to do or grab anywhere you look unless running from room to room is what you're after. npc(s) could be smarter. ( I might have missed it in the previously released material.)
