free VGA memory

[razum]

hi, which program can calculate free video memory or show me all info about video

What exactly do you want to do? The amount of memory a given screen image will take on the video memory can be calculated as

Horizontal Res * Vertical Res * Bits per pixel /8/1048576 = Mb

However, many video chipsets these days store images offscreen to make updates faster, and movement of 3D images (such as in games or screensavers) will need more memory, dependent upon the actual application.

Thanks guys thats what i need, but maybe there is an utility which gives me for example:

Free VGA memory - 100 MB
Used VGA memory - 40 MB

but anyway, thanks a lot for useful info.

Anything that would be able to do that would need to be specific to the video chipset in the computer (in order to get the total amount of video memory installed).

It may be that specific manufacturers have utilities available for their own chipsets, but this will be limited to use on that particular type of video card or chipset.

The amount in use by a 2D screen can be calculated using the formula I gave.

eg 1024 x 768 x 32 /8 / 1048576 = 3Mb for a typical 32 bit business desktop PC.
