    Hi all,

    Just bought a new laptop quiet a high speck, it came with the following graphics card installed NVIDIA GeForce 8400M GS 256MB VRAM. this card apparently can use memory:Up to 1024 MB NVIDIA GeForce 8400M GS TurboCache. Can anyone help explain this and is there a way to fine tuning this card so it does use the 1024 and not 256MB.

    Thanks

    The 8400GS cannot make use of more then 256mb of ram anyway, so anything more would be a waste - but you don't have to worry about it, because the card will take memory dynamically. That's what Turbocache is, a card will have a certain amount of dedicated memory and the remainder is taken from system memory. Having a 8400GS use anything over 256mb of memory would be 100% wasted.

    I hope someone hasn't told you that card is high spec, it's good for older games from 2005-2006 but very poor for the latest ones.

    yeah the card is pretty poor alright, yes it supports dx 10, but it wont play any dx 10 game very well at all even if you have a very high spec cpu and lots of ram. If you turn down the details and resolution in the game you should make most games quite playable.

    Havok explained TC ( turbocache ) pretty well. And if you want more info and some fancy graphs some PR made have a look at the nvidia TC page:
