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.
