Older System?

[Aleron Ives]

Even though your CPU is Sandy Bridge, I'm pretty sure a Celeron clocked so slowly will never be enough for Dolphin. Emulation is far more demanding than running a game designed for PC hardware. Laptop hardware is always more difficult to work with, as it's designed with efficiency in mind moreso than performance. Dolphin relies heavily on CPU performance, and that CPU isn't going to be enough.
