I think, there are 2 processes running as idle task (one of them is Prime95). And I assume that both have the same priority setting, so the OS "thinks", they are equally important (same priority) and gives exactly half of the available time to each of them because Hyperthreading suggests, that there are enough real CPUs to do so (although there aren't).
Try increasing Prime95's priority setting.
