Resident Texture Memory

[Andrew Jameson]

Hi,
I suspect that I've exhausted texture memory on 16Mb cards ... Is there a way to determine how much texture memory is available and how much has been used ?

Thanks

Andrew

No.
Textures can live in more places than video memory.
Check GL_MAX_TEXTURE_SIZE to know what maximum texture size is supported at all with the current settings.
To check if a texture download will succeed you can use PROXY targets (read the glTexImage manual.)
