[] overwolf.media.replay.turnOn: Start_Error_Obs_error

With the new overwolf version we received the known error Start_Error_Update_Driver, indicating that the graphics drivers need to be updated.

After doing so, this new error comes up when trying to use overwolf.media.replay.turnOn.
What does that message indicate? And how to solve it for the user?

Did it work on OW previous version?

  1. Try changing the ow encoding settings to nvenc (not new)
  2. If it doesn’t help, please send us the full OW log folder + dxdiag
