I want to know because I was looking at the system requirements for the Penumbra collection I was considering purchasing, but it said I need 256mb of VRAM, I think.
Also, I'm not completely sure if my PC would be able to run it otherwise. I have a 2.2ghz intel celeron (single core, i think) (I have plenty of hard drive and RAM memory / space) but the graphics look pretty intense for my simple laptop and the FPS perspective kind of puts me on the edge. The only FPP / FPS games I have EVER been able to run smoothly are the old games like Blood, Duke Nukem 3d, DOOM, etc.
VRAM is video memory. Memory for your graphics card or integrated GPU.
Video memory. Either it's memory dedicated to the graphics chip, or it's "borrowed" from normal RAM, depending on what graphics card/chip you have.
VRAM stands for video RAM in this case, which basically means how much memory is available on your GPU card (or alternatively, how much memory can be reserved by your on-board GPU).

256MB sounds a bit much for the Penumbra games. I recall running Overture on my GeForce 6600 GT in the past, which only had 128MB, and it ran fine.

You may want to try out the demos first and see if they run:

It's when you miss a curve shaped like a V, and you just ram in a tree .


EDIT : Hey that rhymes ! I'm awesome !

Most likely you have an integrated intel card which uses system memory instead of dedicated video ram. The end result of that is really poor performance in modern and even some older 3d games.

If you are unsure and want to check exactly how much vram your system has, download and run something like CPU-Z

http://www.cpuid.com/softwares/cpu-z.html

It has a graphics tab that will report the real about of vram your graphics card has. Also as other people suggested, try the demos and see how smooth they run to be sure.

Isn't that what androids dream about?

No wait, that's electric sheep.
okay thanks for the answers!
On a side note:

VRAM can also be slang in certain parts for people (mostly those utilising bureaucratic powers, and often misusing them) as it stands for Veheminently Rectal Arsehole Monitors (hope I spelled that correctly and it gave you all a chuckle - its true!).
