I can provide logs (do you mean launcher console logs?). For memory graphs, do you mean the one at Task Manager while running minecraft? If yes i can post it too by image? Before i added Optifine i'd already try to run a world with lowest settings(graphical, and tiny render), and with or without Optifine it seems i can't see a major difference on how the lag occur, i think it's same.

Updated to forge 1.7.10-10.13.0.1180 (installer), still experiencing lag spikes, even after uses Optifine 1.7.10 HD U A4 with almost all settings set to fast. Mod list: Please give me some ways to minimize/remove the spikes(happened every 1-2secs when i moving around)... If someone can explain to me, why is lag spikes occurs and what's the differences with other lag, I'd be graceful Thanks Edit: RAM allocation on minecraft launcher is 1GB, can't add more because my total is only 2GB RAM, and i run 32-bit Java on 32-bit Windows

Ah i see, okay then i'll try to update to the latest. Thanks anyway.

Hi, i was setting up my own modpack for singleplayer (no multiplayer server) with several mods (below 50 count). It's start up pretty well, till i made a new world (Default world) I had several tech mods like IC2, TE, and so on. It's been ok when i test it out, but with lowest graphical setting: short render, smooth lighting off ; and i experienced lag spikes. Then i tried to add Optifine 1.6.4 HD U D1 to free the lag spikes and it shows this crash report: Feel free to ask for other information you need. Very need for some advice, whether should i add Optifine or not, because before i add Optifine it run normally but had some lag spikes. Or even you guys had some tips to remove the lag spikes? Thanks NB: I used 32-bit Windows7 and 32-bit Java
