|The G560 is an entry level/budget laptop. It's not a performance laptop & it's not a gamer. It has weak Intel graphics & the i3 lacks the turbo boost feature - that means no overclocking. Also, it does not have dedicated graphics memory. "Dedicated" means an actual physical memory chip used strictly for graphics. The graphics memory in your system is 100% shared. There might be a base setting in the BIOS (32MB, 64MB, 128MB, etc) but it's still being taken from the 4GB system RAM. And any other graphics memory beyond the base setting is dynamically allocated on an as-needed basis.|
If you want to perk up the laptop's performance AND you're running Win8 64-bit, double the RAM amount to 8GB (2 x 4GB). Other than that, tweak your system settings & run a cleaner such as Cleaner-Slim regularly. There are plenty of Win8 Tweak guides out there, Google will find them for you.
