I have a 1660 Ti which has 6Gb graphics RAM. However, when I play Star Citizen looking at Task Manager, the game never uses all the 6Gb. It flatlines at 4Gb and the other 2Gb is never used. Can anyone explain this? Is this normal or is there something I can do to get the game to use all the available resources. I wonder that I'm not getting the performance that I should be.
