Hello, I have an ATI Radeon HD 6850 card and it has 1 Gb memory. Whenever I run a game like Starcraft 2 on ultra or BF3 on medium setting GPU-Z will not show the full 1 Gb of memory the card has under the "memory used" area. For example, when playing Starcraft 2 on ultra GPU-Z will show only 408 mb of memory used. What's going on here?? My system is AMD Phenom II X4 975 at 3.6 GHz Sabertooth 990FX mobo 8 Gb RAM ATI Radeon HD 6850 Thanks for any help.
