    OpenGL Bug Report: glGetIntegerv(GL_TEXTURE_FREE_MEMORY_ATI, &mem) causes crash

    burito

      I'm trying to port my program at burito/voxel · GitHub to run on AMD GPU's.

       

      GLint mem;

      glGetIntegerv(GL_TEXTURE_FREE_MEMORY_ATI, &mem);

       

      Causes a crash.

       

      OS is Windows 7 SP1 64bit. Driver version is 14.6 beta 5/27/2014

       

      This is on an AMD Radeon HD 7970.

       

      I'm doing GL compute stuff on a very large 3D texture, and I can adjust the size of the texture, but I need to know the VRAM in advance so I can compile my shaders with the correct values.
