Seriously. Same here. Bottleneck is in the way the software processes data, not our devices. I can't even get past 33%. CA already is at 11fps, with most features disabled.
Can you be more specific? Latency between camera movement and what you see on the screen? Or audio latency of the lip sync? Some other kind of latency? Also: please let us know the version of Ch and the version of your operating system. Ideally Ch would prefer 4 or more CPUs.
