Ok so I have already heard some people say it's not worth it or it causes more problems than it fixes but I wish to be the judge of that myself. That being said let's move on to my issue. I have already tried\ optifine 1.5.2 U optifine 1.4.6 hd and U No I did not put more than one in at the same time These are the ones I was told I would need but regardless they all caused my mojang screen to be replaced with a gray screen and my game would not load leading to me having to delete the mod and mc jars. Yes I placed the files from the optifine downloads into the modpack.jar not the minecraft.jar So that being said am I putting the wrong ones\ Am I doing something wrong\ Assistance would be greatly appreciated. Thank you
