lol HOW DID U KNOW i did get a way better computer with a gtx 770 and so on and now i dont get lag i even get a ton of fps but i still get glitches/freezes for less then a second and it happens over and over again. though i can still play idk if optifine fixed it though i just added it :)
i have so much lag i can barely move i cant even pick anything up, please either fix the modpacks glitches or straighten out the modpacks or something to fix the lag, even optifine wont help it!!!
