      Description

      In 1.4.7 I would receive 60-80fps with a HD texture pack, however as of 1.5 I have dropped to 40-60fps on a standard pack and 30fps with a HD pack. I am also now unable to record footage of my mods. I tried 13w12~ along with 1.5.1 and while 13w12~ reduced lag slightly I was still unable to hold 30fps up constantly while recording. I also receive lag spikes that shoot up to 100fps then back down to low levels and up to around 50fps again. I believe this problem is to do with the improved lighting engine in 1.5
