Could have fooled me - your post is better than some native English-only posters.
Two solutions I've seen mentioned, both have some risk, and I haven't tried either. The first is to disable the on-chip graphics in the BIOS which will force the discrete card to be used. The second is to uninstall the Optimus software.
Definitely use the nVidia GPU. But install this WHQL certified driver first:
Make sure during the install that you choose to do a *clean* installation. So check that box. It will uninstall the previous, reboot, and restart the installer to complete the new driver.
ADSK publishes a list of certified drivers and graphics cards that are thoroughly tested and supported. I suggest you consult this list for to see if your graphics is supported, if so download the recommended driver. Generally you should purchase a professional graphics card Quadro or FirePro for this the following reasons - performance, functionality, certification and support.
