I too have this problem. Before pre-release 1.5 I had beautiful framerate, but now it lags like all hell broke loose. I think tested on Minimal lighting, same thing. Then I tried with NONE, and it completely fixed the problem. Thus being said, this is definitely a lighting engine problem. Please fix it!
