Heavy Stuttering in Villages

wasn't speaking of just gaming performance... system performance. you're adding wear to your HDD with 8gb, bcs you're using pagefile a LOT more often, with 16gb it's barely used for the most part, except to allocate pages.

it's tru it might only give you 1-2 fps at best, if any (depending on game), but it will increase application load times, alt-tab performance, multi-tasking, etc... overall system performance will be better.

anyways, you can't argue with IT, or they will refuse to fix your PC next time...

GPUs don't read and write directly to system RAM, as it's too slow so for the most part, system RAM doesn't directly affect frame rates. But it can definitely impact overall gaming experience..

they do. it's called DMA (direct memory access). it's not a magical golden egg tho. yes, it does improve cpu performance, cuz much of the copying work can be offloaded, but that memory is in a locked state, so nothing else can operate on it basically. cpu can do something else while it waits for operation to complete, then device/gpu sends an IRQ to the cpu, tell it that it needs to process another command. without dma you'd be waiting forever for your cpu to complete the request.

Well what I meant was that GPUs don't read and write to system memory when it comes to graphics processing. System memory does not have the bandwidth for 3D graphics, unlike VRAM.

I know that the system memory acts as a buffer for the VRAM though, so yes, the GPU would need to access it for textures and other graphics related data.....but not for actual processing..

yea, in the past the cpu used to have to do all that work, but that's a very distant past ;p maybe 20 year ago or something i remember. when did DMA come around, probably 8086?
