I have a problem with my laptop graphic cards enabling / disabling.

[Arthes]

Hello guys , I have a lenovo G400s.
Specs :
i5 3230m 2.6 ghz
GT 720M + Intel HD 4000
8 GB RAM

and the problem is , when I disable intel hd 4000 when im trying to play tf2 or other stuff with the GT 720M , the display adapter [ right click and go to screen resolution , then go to advanced settings ] changes become Microsoft Basic Display Adapter and it didn't change to the GT 720m. Anyone help me please? This is really annoying. Oh yeah , when I enabled both of them the display adapter is still intel HD 4000. and when I play tf2 and type mat_info it said that my GPU was still Intel HD 4000. If I disable the HD 4000 , in the mat_info it says I'm using Microsoft Basic Display Adapter. Hope anyone can help!

U can't disable Intel HD; if u do the NVIDIA can't work.
That is how Mobile Hybrid GPUs work; unless in a Desktop.
The dedicated must also use the onboard GPU in order to push the data through frame-buffer and then to the screen.

If you want to use the NVIDIA GPU, set that to be the default in NVIDIA Control Panel > Manage 3D Settings

Best bet now is uninstall all the NVIDIA Drivers & Software from Control Panel > Programs and Features. Reboot as needed. Then uninstall the Intel Graphics Drivers. Reboot as needed.

Then install latest Intel HD GPU Drivers; reboot
Install latest NVIDIA Geforce Mobile (700M series) Drivers; reboot.

Set NVIDIA as the default one under NVIDIA-CP

I'll try that but the Manage 3D Settings in the NCP thing doesn't work at all. I've done that all the time.

What you mean doesn't work? How so?
Did u ensure u clicking APPLY after making such a change in NVIDIA Control Panel?

You can then download and run GPU-Z and let it run in background while u run a benchmark or play a game for testing purposes; then switch back to GPU-Z > notice the selection at bottom there for GPU(s) Intel vs NVIDIA and see if there are high load on the NVIDIA. If so, then it is being used properly.

If you not getting good performance; well that is because both Intel HD series and NVIDIA 720M are quite poor for gaming in general anyways.

They're not really bad , I can run TF2 on 60 fps on the INTEL HD. But I wanna test my Nvidia 720M.

Notice : I'll try all of your tricks and I'll give news as soon as possible.

Performance wise both of those GPUs are roughly the same.
So don't expect much better FPS out of the NVIDIA 720M
But overall the NVIDIA should support more graphical features than the Intel, and many games have issues running on any Intel GPU, so yea... GPUZ can show u what GPU is actually being used and such when under loads via DirectX/OpenGL apps/games.

Oh boy , this seems interesting.

The Nvidia card will take over when needed, the Intel card will be there for ever.

gt720 isnt any better than the intel hd, but it does use its own vram
it will be much better for ogl games, but dx performance will be very close

both are still used when the nvidia card is in use
the nvidia card creates the frames for the intel hd to display
