I was checking whether a few games would be compatible with my laptop on this website - www.systemrequirementslab.com
When I checked for the game World of Warcraft: Cataclysm, this is what it showed in the graphics section

It says I have 1.7 GB Video RAM. Now when I did the test for Call of Duty: Black Ops II here’s what I got

64 MB of VRAM only! L When I did this with FIFA 12 it showed 1.7GB VRAM, Battlefield 3 64MB VRAM. Here are my graphics card specs

Here it says VRAM is 64 MB. So my question is whether I will be able to run World of Warcraft: Cataclysm as the required VRAM is 128 MB. Also I don’t think something is wrong with the website

With Intel HD 3000 graphics, the graphics subsystem reserves a fixed minimum of system memory for video RAM, and then what's called Intel®  Dynamic Video Memory Technology allocates and releases memory up to a specified maximum, in a dynamic fashion. Tests done to determine compliance for video games are likely to identify the reserved minimum as the amount of dedicated video memory. It's been a long standing problem. Have you checked BIOS settings to see if there is a larger option for the reserved minimum? If it is fixed at 64M it may not be possible to solve.

I have a Toshiba Satellite P745. In the BIOS menu I don't have the advanced chipset features so I'm not sure whether 64MB is the max.

Even if my graphics card reserves a fixed amount of memory of video ram, how do I get 64MB in some cases and 1.7GB in other cases?

It just depends on whether any particular test correctly analyzes and accepts dynamic memory allocation nor not. Because of the way the Intel DVMT system works, if the test identifies the amount that is unquestionably available (e.g. 64MB) as the Dedicated Video Ram, rather than what can be made available, that's the result. If the test is set up to detect and accept the potential larger allocation as Dedicated, you'll get the other outcome.
