I have the same problem, but i don't have a NVidia Graphics card so i have no idea how to fix it.
I have an Asus 15.6'' 2nd Gen Intel Corse i3-2350M Laptop
IntelĀ® HD Graphics 3000
Windows 7 64 bit
Java 7 update 5
8 Gigs Memory (1GB allow coded) DDR3 SDRAM
Dual core 2.3 Gz
I get around 40 Fps Highest settings on vanilla Minecraft. Tekkit starts out at 30 fps for about 5 seconds then BOOM 5-10 fps. I haven't even built any machines yet.
ANY help would be great thx.
