Yes, for me it works fine on normal texture packs, but I really wish I could use high-res textures. Also overload, have you tried making you're minecraft a tekkit/ technic build instead of using the launcher. If you haven't it may help reduce lag, go to this link: http://www.mediafire.com/?84roljqg9jwd595 1. Make sure you backup you're whole .minecraft by placing into another location 2. Delete .minecraft from Roaming, don't forget to keep a backup 3. Open the .rar file and place .minecraft folder into Roaming 4. Start minecraft and do not update You can put in your old saves, however it may not load properly, as I had this problem. I would recommend starting a new world and if you want use the tools to restore your world, it's your decision. It usually works best without texture packs but if you really do want one try out 16x or 32x, I don't recommend it since you're graphics card is worse than mine, by a long shot, so you'll just have to stick to default. Feel free to mess around with optifine to fix it, turn off smooth lighting definitely, and turn off MAtmos. Hope I was of help.

I understand that this is a bit late, but I am also having similar problems with tekkit. Usually it get 80-95 fps when walking, 60-80 fps when sprinting and 55-80 fps when flying. I followed the steps and turned off smooth lighting and MAtmos which increased by fps by about 10 overall. However it slowly decreases to about 40- 50 fps, then drops to 30 fps. It will then either drop slowly, but usually it spikes to about 5-10 fps then freezes. My laptop specs are: Processor: Intel Core i7-3612QM CPU @ 2.10GHz RAM: 8GB System: 64-bit Java: Not quite sure, but it seems it is 32-bit, version 7 update 7. Graphics Card: GeForce GT 630M I got Minecraft to use the graphics card, that helped a bit but the fps only increased by maybe 5fps.
