Does the OpenGL backend really need a texture cache?

[kirbypuff]

Is the OpenGL texture cache really necessary when GPU drivers (AMD and NVIDIA) already do the same thing?
It's redundant and a waste of CPU / IO resources / disk space.

Hell, no. Our texture cache tries to save redundant uploads. There is no way for a driver to do this for us.
Are you talking about our texture pool? Indeed, driver already do this, but much less efficient.
