depends on your motherboard but you can change the amount of shared memory in you computers bios, when your computer starts press the "del' button and the bios should come up and the you can change it there. just look around in the bios.

No amount of VRAM will make slow integrated graphics play a relatively demanding game like DayZ well. IGPs share system memory, which is managed by the OS automatically.

What about when and if it is possible for sims 4, i already tried enter UEFI through my Backup and Restore but it had no option for changing the vRam, i run sims 3 with little to no problem unless there are a crap load of people on screen then it lags, but sims 4 i heard is suppose to run about the same but a little more demanding (like miniscule in terms of required graphics)
