Interesting work around. You could also just not run Pitool except to make a settings change.Once SVR picks up the new setting Pitool doesn’t really need to be running until the next time you want to change a setting.
I stopped upgrading at PT 261 so can’t speak to the latest ver. Works great and saw no reason to move to later versions (if it ain’t broke) and in some cases reason not to, based on some other’s posts.
Then i find it odd you need to run pitool to run IRacing in SVR. I can’t test IRacing but I seldom launch Pittool if i am not making changes in it. Can’t recall having to have it running to actually play any of my SVR games of which I have several dozen.
Pimax services runs at Win startup. Actually running the Pitool app isn’t necessary except to make changes for things like PP, FOV, Foviated rendering etc. Then you need to have PT run until you launch SVR so it can adjust to the new settings. After SVR runs you can shut down Pitool if you wish until the next time you make changes SVR needs to pick up.
Unless I am changing settings I never run Pitool other than to launch OpenXR titles like MSFS and DCS or Oculus titles. SVR titles work fine without it running. Been that way for years without issue.
As I said, in the background The app itself hardly uses any resources. or does it? Haven’t used it like this in ages as I only run the Pi processes when I’m also using VR, thus turning the HMD on and off
