i use:
nvidia geforce GT 525 M with cuda,
total available graphics memory 2806 mb
dedicated video memory 1024 mb
system video memory 0 mb
shared system memory 1782
(in the display adapter properties, in dxdiag approx. total memory 2761 mb)

when i instal PES 2014, the specifications of vram 992 mb, shared 1,8 gb ( my RAM 4 gb, windows 7 64bit)
and the score is ok, not good.

so, how i can increase or manage the vram to the optimal, becasue in medium or high setting in PES 14 needs minium 1024 mb of vram?

No -- the video card itself will have a certain amount of VRAM that can only be used by the video card depending on the card itself (in your case it is 1024MB as shown in the dedicated memory (dedicated video memory 1024 mb)) -- then Windows will set aside a portion of the system memory for sharing amongst the various hardware based on how much system RAM is installed -- In most cases this memory will not be used by the video subsystem since it is usually slower than the VRAM that is directly on the video card and is only used when using a complex program that requires more than the 1GB of VRAM that the video card has...

You don't -- windows adjusts it automatically and will only use as much sytsem shared memory as resources will allow and will free it if needed for other processes. (thus the reason it is called shared - as windows will distribute it to the part of the system that needs it - the amount that it shows is based on the total amount of system memory that is available on the computer and is not adjustable by the user.

(in your case the OS is setting aside 1782MB as shown in the "shared system memory 1782" )

Any time that the video card is using more than 1024MB you will probably notice stuttering and slowdowns in the program you are running (since it then begins using the slower system memory causing a slowdown of the entire video system (but it will still be faster than waiting for the VRAM to be freed and rewritten if that shared memory was not available) so you will want to adjust in game settings down until the game uses less than 1GB (1024 MB) of video memory for most of the game (ie. lower resolution- reduce AA,AF etc.) in order to get the best performance.

AS far as adjusting the amounts available ther is no setting to use since the windows OS can better handle the resources on it's own rather than having the end user try to tweak the settings which could actually cause serious slowdowns or crashing if the settings were set incorrectly. So the only way to have some control over it would be to turn down in game settings until the game would run in the 1024MB of VRAM and not need to use the shared memory that slows performance as VRAM is much faster than the system DRAM.
