What to change for Rock Band 3 under the CPU tab in RPCS3's Custom Configuration.

A screenshot of Rock Band 3's CPU custom settings, showing SPU XFloat Accuracy, SPU Block Size, Preferred SPU Threads, and Thread Scheduler highlighted in blue with a dotted outline.

  • A blue square with a dotted outline. Improved performance, depending on machine:
    • Change “SPU Block Size” to “Mega” - Ties smaller SPU compiled together, which can help machines with fewer cores/threads. Drastically speeds up game startup time on certain machines.
    • Change “Preferred SPU Threads” to “1”, “2”, “3”, or “4” - May help prevent stutter caused by CPU overloads on systems with fewer cores/threads. Start at 4 and lower it one by one until it improves.
    • Change “Thread Scheduler” to “RPCS3 Scheduler”, or “RPCS3 Alternative Scheduler” - FOR CPUs WITH 12+ THREADS ONLY! May help with thread distribution to prevent microstutters.
