This is amazing! Might this lead to faster TR2 or was some thoughts from TR2 used to speed up TR1?
The optimizations are specific to TR1.
In the future when light portals are made will it speed up more or is this automatically detecting the holes where light comes through to the point where light portals would have little improvement?
When sky portals will be available, there will be an additional boost (for all engines). Current tests show this boost but we have to fix some issues first.
