I have lenovo y50-70 laptop, I've been using it for about a year now and everything is good, a week ago I uninstalled the windows and installed a new one, since then there's somthing wrong with the GPU, when I run after effects I runs with the CPU not the nvidia card, any help ?!
I have the same exact issue since I'e just installed a new windows, any help ?!

"same exact issue since I'e just installed a new windows"
"since then there's somthing wrong with the GPU"
was it working before or not?

"CS6's new 3D ray-tracer uses CUDA with select NVIDIA cards, but the Classic 3D renderer (the same renderer available in prior versions of Ae) renders only on the CPU.
One of the ways to speed up After Effects is to enable multiprocessing. This exploits multicore CPUs by essentially launching multiple copies of the After Effects Classic 3D renderer and rendering multiple frames at the same time. Each instance of the renderer requires its own RAM.
Adding system RAM so you have at least 2-4 GB per core on your computer will help you speed up your previews and renders by allowing you to make better use of all the CPU cores in your system."
based off of this information it seems like alot of the software programing for after effects is suppose to run on the cpu and not the gpu. only specific functions/conditions run on a gpu.

thanks for answering,
when I start Ae there's a message appears that says " Ray tracing on the GPU requires an approved NVIDIA graphics card and CUDA 5.0 or later. This may require installing the current display driver. For now, ray tracing will use CPU"
before installing the new windows this messages never showed up. After I installed it I installed the NVIDIA driver and it appears in the Device manager but when I run dxdiag it only shows the Intel graphics card so I don't know if the NVIDIA card is working properly or not, but the device manager doesn't show any thing.
when I open the previews in the Ae it shows that ray-tracing will use CPU not GPU and the OpenGL and CUDA sections are not available!

You'd want to install the video drivers from the laptop vendor not nVidia, using the reference nVidia drivers in laptops can break the dual graphics support
