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

Question asked by burito on Jun 12, 2014

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.
