The default (i.e. CompLevel_full_optimization == 4). It doesn't matter though on this particular line, because this in-queue change optimization is for CompLevel_full_profile compilation requests only, and that level is illegal with both C1-only and C2-only configuration (including when tiered is off). So, this if condition is never going to be true in these modes.
