What to change for Rock Band 3 under the CPU tab in RPCS3's Custom Configuration.
- Tweak depending on audio hardware and CPU:
- Adjust “Audio Buffer Duration” depending on system.
- Lower values give you less audio latency but use more CPU.
- Higher values give you more audio latency but use less CPU.
- Vocalists are affected the most by this, as a higher latency creates a distracting echo. Instrument players can use calibration to compensate regardless of audio buffer setting.
- You can change this while the game is running, but it will require re-calibrating in Rock Band 3’s system settings.
- Change “Audio Out” to “XAudio2” - While most users should stay on Cubeb, a couple of people have experienced better performance with XAudio2. Your milage may vary.
- Adjust “Audio Buffer Duration” depending on system.
- For Vocalists:
- Set Microphone type to Standard or Rocksmith.
- Select an input device in “Mic1”, “Mic2”, and “Mic3” for vocals. If not playing vocals, Mic1 will be used for voice chat.
- Once again, keep in mind that playing with framerates higher than 60 may cause issues with vocal detection.
