I'm excited for this revamp of the rendering system, which if implemented correctly should be a performance and quality uplift. That said I wonder what happened during development that caused the older PQS+ (procedural quad system) to degrade in performance so badly.
https://youtu.be/NAVbI1HIzCE?t=970. In this video at the timestamp, Jason Booth who worked on improving PQS+ managed to get sub millisecond performance from it (shown in 24:40 in the video). Given this, is the game's poor performance actually the result of PQS's limitations or something else? It would seem premature to invest this much effort into revamping the renderer if it turns out to be an accidental regression. Personally I'm waiting for the physics system to be improved over KSP 1 before I decide to repurchase the game.
