I have had this exact issue as I pretty much saw coming went from 40 to 50 frames on 32 bit to 15 on 64..........nothing seems to happen as its supposed to on my computer.....idk what info I should give but some of my specs are below. Note I have tried the control panel fix and the validating files and nothings worked...using this info would someone be able to guide me through the best parameters in the launcher that I should maybe be trying? I had to use JE malloc for 32 bit and it smoothed things right out for me however ive been told to not us any mem alloc for 64 bit so for this reason ive left all of my parameters default until I get answers on how I should set it up....theres not exactly a guide on this....or at least I haven't found one
