thank you very much for your help and information. this shows that there is a huge problem with the driver-software of the E520.
in "3ds max" i can display what hardware the program is using and it says "0: [X]Mobile Intel(R) HD Graphics \\.\DISPLAY1" while the "Catalyst Control Center" shows at the same time that 3dsmax is using the "AMD Radeon HD 6630M". but that is completely wrong, 3dsmax is definitely using the slow Intel graphics, therefore running extremely slow and with graphical errors.
if it was just one game that wouldn't run... but a professional software - that is not acceptable!
i hope there is or will soon be a solution to this BIG problem. i don't want to pay for a graphics adapter that i'm not able to use
thanks for any help!!

i still haven't found any solution, if the E520 just does not having working drivers, i may have to return the laptop (although i actually like it), but it's completely worthless if i can't work with it
please - if anyone knows any help - i really appreciate it!!
or even better - if LENOVO would read this and upload a fixed driver that would do what was promised when i bought this thing!!!

Your programs are OpenGL based, right?
OpenGL applications and games cannot use the discreate graphics card on Dynamic Switchable Graphics Laptops.
Lenovo could release some sort of update/BIOS update that would fix the problem/add an option in BIOS to switch to the discreate GPU (fixed instead of dynamic)..
Although it might be a problem with the AMD software...

sorry, no the programs are not openGL based.
in one, i can set between an intern mode, direct3d and openGL. in openGL i don't see anything anymore, so it doesn't seem to work at all on the computer.
but even in direct3D (in all 3 modes) the laptop does only use the Intel chips.
it does not switch the 'switchable' graphics.
i have tried to get a solution from lenovo, but i didn't get any useful help from the techsupport on the phone. i think they don't care about it.
it may work with games, but for anyone planning to buy this to work with, i can only say look for something else =(
