sceKernelReadTsc devolvia o rdtsc cru, e em hosts com TSC diferente por núcleo (3,9 s entre núcleos num Xeon E5-2680 v4) o jogo saltava no tempo quando uma thread trocava de núcleo. O TSC passa a ser o contador do processo em nanossegundos (QPC no Windows), com frequência de 1 GHz, no runtime e na biblioteca de GPU. Refs #42
