Low GPU utilization when "Optimize game latency" turn on

When I enable the "Optimize game latency", my FPS drops, and GPU utilization decreases.
When I disable "Optimize game latency," FPS is stable, and GPU utilization increases, but the latency becomes inconsistent, making it difficult to use.

The picture is the difference when looking at exactly the same place.
 
Maybe it's the same issue. [(https://github.com/alvr-org/ALVR/issues/1901)]

Is there a solution for this problem?
