Thanks! Works better.
A certain oddity (intentional?) is that even at spec_point 0.3, warp rifts cast huge intense lights. Normally this looks alright, but when a wing of 6 fighters warps in all at once, nearby capships basically turn white from the intensity. This is at 3 dots/5, so no glow points, no laser lights.
Overall, the new rendering code seems faster than the old code that I capped to render at max 4 lights a scene. There was much enjoyment to go back and play Delenda este with smoother framerates.
Edit: Also weird: Cap ships receiving beam fire will be lit by the beam lights until they die, at which point their debris/exploding husk loses all lighting from beams. Maybe this always happened, but lights are behaving better and more reliably overall IMO, so this issue stuck out to me more.
