can anyone help ? lags and stutter after someone drops

@brucelee This shouldn't have anything to due with the lag/stutter issue you're experiencing, but you have a sound bug which you can tell by the SND/XACT warnings. This sound issue can result in unexpected behavior, including crashes. Simple fix steps are:

  • Windows key > type: Control Panel > Open > Sound > Playback > select the Device you use:
  • Configure > Stereo > finish configuration,
  • Properties:
  • Enhancements > Disable all enhancements,
  • Advanced > 16 bit, 44100 Hz,
  • Spatial Sound > Off,
  • Restart or Shift+Shutdown (not just Shutdown) of PC

If your headphones come with any applet/program, then you may want to disable that & try using the headphones without it. Similarly, if they use a USB or Bluetooth dongle to connect to the PC, see if you can connect directly without the dongle.
