The newest release of Nvidia profile inspector seems to have fix my mirror stuttering issue. By setting DXR to disabled - (under 5-common Enable DXR), the stutters have gone away and the game can be played with mirrors enabled again. Not surprisingly, the issue seems to be connected to Raytracing which came with the update that introduced the stuttering issue. This is why not everyone experiences the Microstutters, I'm guessing it only affects Nvidia cards capable of Raytracing.
