Agreed. 132 may not allow us to trigger the performance boost but it doesn’t mean that Pitool causes the low GPU utilization issue.
Yesterday I stopped all “Pi” processes and services and tested rFactor 2 on a 1080p monitor. I obtained the exact same GPU utilization as with the Pimax; between 51% and 71% while racing. I tried with low details and got an average of 380 fps. With all details and eye candy features set to max, I got an average of 150 fps. The detail level did not affect the GPU utilization; it always averages 60%.
