Is there something i'm doing wrong that is causing my game to lag out when combining these two mods? I'm using forge 1291 because Optifine 1.7.10 says it is compatible with 1291, and i'm running a host of other mods, but the problem arises when i have gregtech (your gregtech port) and thermal expansion running at the same time. When the game crashes there isn't any crash log either, it just says "Game running 3171 ms behind server shut down" or something like that. Help?
