Directly to the point. When I am playing FTB (Any modpack of the launcher) I get this really low-fps and it makes impossible for me to play. At first I thought it was just cause it had so many mods and my hardware couldn't handle it and that was the cause of the lag. Actually, I've did some tests, and I've discovered something interesting. When playing vanilla Minecraft my GPU-load stay around 40~70%. My fps stay stable at 60+. When I am on FTB the GPU-load stay at 4~7% and I get 10~20fps. Here some screenshots:

FPS test with complete vanilla (No optifine, nothing) :

FPS test with FTB:

FPS test with only-Forge 6.6.0:

All the configurations where the same:

Render: Normal
Graphics: Fast
Particles: All
Windowed mode
Smooth Lighting: On
View Bobbing: On
Advanced OpenGL: On (I use that when I have a good amount of chunk loaders in the world)

I've used GPU-Z 0.6.6 for the tests.

My PC do have a integrated graphics board. And also an off-board GT-520M (I know it is not that good, but shouldn't give me that fps and the proof is the GPU load). It has an 4-Core I3 with 2.1Ghz. And 4 GB RAM.

I am sure that my PC can run without so many lag. Sometimes when I am using a texture pack my fps stay stable at 60 fps (And so the GPU-load goes up).

I can give you guys every information to help me play this awesome modpack without lag. Thank you! :)

Ps: My native language isn't english, I tried to do my best xD

Edit:

I have to say, I've tried a good amount of things. My graphic card drivers are updated Java also, and I am playing the game in "Max FPS" mode.

I don't use optifine, it actually just make things worse. I did try to install it again, didn't changed nothing.

I have read somewhere on these forums that computers sometimes do not recognise Minecraft, when played through the launcher, as a game, and so it will not apply the full force of the graphics power to it... I believe it had to do with integrated and dedicated cards, but I don't exactly remember.... :(

It is interesting that the "GPU Core clock" has such a large difference between the top/bottom screenshot and the middle one.

Well, sometimes when it is in the Menu (Also happens in the "Esc" menu) it uses the GPU, but when I try to play the game, it stops. Quite annoying situation :/

I will add to the topic. I do have all drivers updated and I am playing in "Max FPS". I also can't find any battery configuration that could interfere with this.

There isn't any way to make Java always use my GPU or some command to run it using the GPU?
