There are three major options when SG capability is enabled, 1) Allocate everything when possible from GTT memory 2) Allocate everything when possible from VRAM 3) Allow both VRAM/GTT to be available Each has its own pros/cons, and it has not been decided which direction is going to be used for all PCs. So it seems beneficial to provide all the options.
