Under system profiler: Graphics my Intel HD Graphics 3000 is reporting 512mb of Vram I thought it was supposed to be 384mb. Also the Intel HD Graphics 3000 is showing no monitor attached while the AMD Radeon HD 6750M is showing the LCD display attached with the correct resolution. I thought the ATI was only used when the GPU was under heavy stress such as video encoding. By the way my ATI vram is correct reporting 1024mb of vram which is correct according to Apple Specs. I have no external monitor attached. Any insight would be truly appreciated. Thanks.
