Occured when I tried to debug the project- HiDef profile been used.
No suitable graphics card found
Could not find a suitable direct3D devie that supports the XNA framework HiDef profile
When I use Reach profile it says
Error 2 XNA Framework Reach profile does not support vertex shader model 3.0.
Tutorial8 - Optical Marker Tracking - Windows
How can I solve this in either way?
