PresentMon can't coexist with multiple session

Open cdjzzzz opened this issue 6 months ago • 1 comments

I created a session myself using the PresentMon SDK, but I found that it cannot coexist with the official PresentMon tool. When my session is active, PresentMon throws error 1450.

Is PresentMon supposed to support multiple instances or multiple sessions running at the same time? Or is there something I might have missed?

As my debug, it ends up with here Enable(...) at PresentMonTraceSession.cpp calling EnableTraceEx2(..) return 1450. Any idea about this?
