Question Graphics card

I have a gt 1030.its vram is 2gb gddr5.but why is it showing 1959 mb in every game?I have windows 7.

You have a gremlin stealing tiny bits of video RAM to feed it's kids. You will probably notice it with your hard drive also, drive is 500 gb but it will show up at 470 or something.

Cats are good defenders from gremlins, I suggest 2 so they can work in shifts.

Or just ignore this since it's not an issue. You don't often see the exact amount of memory that is on the box in reporting tools.
