I finally have a chance to reply.
Notwithstanding all the other things people above have mentioned, it seems that periodically when a SteamVR update occurs it breaks something with Pimax. Pimax should be given a heads up before a SteamVR update, and they should have access to that code to find any incompatibility issues with PiTool. Also, SteamVR should tell Pimax any changes that are going to be made beforehand so they can prepare.
And I still don’t understand why PiTool can’t be integrated within SteamVR. I understand that Valve is now a competitor because they’ve come out with their own headset, but for the sake of standardization, all headsets that are supported by SteamVR should have the ability to be integrated, eliminating the need to have a separate tool. It would be good for the consumers and good for SteamVR if the user only had to only launch one program.
