There are indeed two versions:  Intel-only and Intel-hybrid video.

There is no way to manually increase the video allocation on Intel-only video systems.  Your application is looking for dedicated video RAM your system does not have -- you need a more capable notebook to run whatever you're trying to run.

Hi,

Thank you for writing to the Dell Community Forum.

Unfortunately, notebooks cannot be upgraded with dedicated graphics memory, as the entire motherboard needs to be replaced (including the CPU, which is soldered to the board), heat-sink assembly and likely the power adapter.  The discrete video card option can only be selected while placing the order for the new system and cannot be upgraded later. 

The 32 G is  fixed, non-adjustable frame buffer.

The video RAM is the system RAM - this system has no dedicated video RAM of its own.

When you see a program message about the dedicated video RAM, it means the program needs an AMD or nVIdia GPU - it will not run with the Intel GPU.  The only solution to that is either to replace the mainboard with one having hybrid video (which, beyond the cost will void the warranty - and on newer systems, will mean replacing the CPU as well) or upgrading to a higher-end notebook entirely.

Not on this system, no.  You'll want a minimum of an XPS system - better, Alienware - for that.

The system is better suited for office work and internet browsing than for gaming.  If you're looking for games, look for strategy/role playing type games.  Anything with fast action or high-powered graphics just won't be suited to this hardware.
