maj00r	85b76acca5	perf(sleepers): the instances of the sleepers and timbers of a track sent to the gpu once, as it's laid, and kept there in a buffer of their own; in each pass the runs of them in sight turned by the modelviews of their cells into the instance buffer of the frame by a compute pass, one dispatch and one barrier a pass, and drawn in one instanced draw for each model, part and level of detail, in place of the cpu turning every instance every frame	2026-10-24 01:40:34 +02:00
maj00r	f155956669	perf(sleepers): the rails of each track for the fastenings worked out once and kept until its geometry is made again, it goes far or the crossings change, not again for every track laid around it; the fastenings laid only out to 30 m past where they're drawn, the tracks further out keeping their beams to lay them on as they come near; out past 50 m the tracks laid while the laying in a frame took under 2 ms, the rest in the frames after	2026-10-24 00:23:50 +02:00
