Hello everybody, I bought a few monts ago a MSI Laptop with a dedicated Nvidia GTX880M graphic card with 8GB of VRAM and I was quite happy with its specs till now.... I have been playing many games since I bought my laptop, which is a GT72 2PE i7-4710HQ 2.50GHz with windows 8.1 x64 and 32GR of RAM, but none of them was very demanding, so I think my graphic card was using just a small part of its memory... The new games I have installed are very much demanding and so I found out that the max amount of VRAM they can read from my graphic card is about 4GB and I don't know why... This problem gives me bad performance, lag, and stuttering, which is supposed to be something I never have to worry about with such a powerful graphic card and laptop... I have been trying to found out where the problem comes from and I am pretty sure that it comes from the graphic card, which only uses half of its abailable memory. GPU-Z shows that my graphic card has indeed 8GB of memory, but it uses only 4GB for all games, could you help me with this please? Thank you very much in advance.

what games?

Rome 2 Total War, Attila 2 Total war, The Witcher 3 and specially Skyrim, which is supposed to read only 3GB of VRAM but you can actually force it to read as much VRAM as you graphic card has with a program called ENB Boost. The max amount of VRAM that those games read including Skyrim is 4GB, and after contact a few people and looking for in internet I really think that my graphic card only uses that amount of VRAM.
