Hey im running my pc on onboard graphics, its meant to be Ati HD4200, which is pretty fast 4 onboard, but it actually runs games really slow. Is there anyway 2 dedicate more memory 2 it or make it go faster? My system specs are AMD athlonII x2 2.8ghz, 4gigs DDR2 800 and im running on Windows 7 64bit. Any ideas? Would the bios of my MB have anything 2do with it?
As everyone else has said onboard graphics are going to be quite limited for games, they're intended primarily for web surfing, playing movies etc. If you have any interest in gaming get a discrete card, I'd go with a Radeon 4670 or better (start at $70ish on newegg) depending what your budget is you might want something better.
That said some radeon igp's have 'sideport' memory in addition to shared memory. If yours does there should be a bios setting to enable sideport only, shared only, or both. This can have some effect on performance, but regardless will not equal a real card.
I updated my drivers and that helped alot, i played a few good games but the current top games i had 2 get a graphics card, or play on 800x600.. so workd 2 a certain extent, ati on board graphics are pretty good
