I set up Nvidia PerfHUD and I made a simple test. Loaded a texture, the VID MEMORY graph is showing me a value (how Mb is occupied in the video). 1. Why if I SetLOD for that texture to have a lower quality the VID MEMORY decreases but after 2 seconds the amound gets the same as the original texture.. 2. Why the graf is not to 0 if I dont have any texture ? If my application is just clearing the buffer. Thanks
