Hi.I have a problem with this modpack. Actually , with all of them. When I play Attack of the B-Team , I don't get more than 20-25 fps and sometime it drops at 1-5 fps. I have this problem only with Technic Launcher's Modpacks. In Minecraft Classic or modded by me , I got 60+ fps. I don't have a weak PC , I can run BF3 at Ultra with 50 fps... so I don't think the PC is a problem.
