I am developing OpenGL Applications on my new Intel(R) HD 4400 (Haswell Architechture) boards. My OpenGL Apps with shaders are working fine. But I need to query the board to get the available Graphics Memory. At runtime I need to know how much memory is utilized so that I can control additional Texture loading in my App.
The GPUdetect sample at Intel Site just gives the maximum available, that too using DirectX. I searched in 4th-gen-core-graphics-dev-guide.pdf but could not find the proper methods.
Can you please tell the APIs I can use to query the graphics memory utilization at runtime?
NVidia/ATI provide APIs that we can use too see the memory utilization when an OpenGL App is running.
