DJBarry, you've consistently been warned for talking about things you don't understand. Raising the IR or AA bottlenecks the GPU. It will reduce Dolphin's emulated speed, but won't affect how well your CPU is doing its job for Dolphin. Additionally, it's evident that the OP is using MSAA, which is not taxing at 8x for his GPU. His IR and AA are just fine.
