Hello Folks! I was checking some stuff in my computer and my Operating Systems says in different sections /applications that the GPU have different memory capacities, none of them advertises the 6 GB, it only shows up that capacity in GPU-Z for example, during games nothing can take more than 1.5GB of VRAM maxing them out completely and textures looks somehow washed out most of the times. Is this some kind of Windows 7 Limitation? Can i change this somehow? I'm reeeally confused!

Click here if you can't read the numbers

Maybe there is something wrong with the Card? Its a Zotac Reference card by the way.

Thanks for taking your time to help me out.
