PresentMon is a tool to extract ETW information related to swap chain presentation. It can be used to trace and analyze frame durations of D3D10+ applications, including UWP applications.

Binaries for main release versions of PresentMon are provided on GitHub:
Capture target options:
-captureall Record all processes (default).
-process_name [exe name] Record specific process specified by name.
-process_id [integer] Record specific process specified by ID.
Output options:
-no_csv Do not create any output file.
-output_file [path] Write CSV output to specified path. Otherwise, the default is
PresentMon-PROCESSNAME-TIME.csv.
Control and filtering options:
-etl_file [path] Consume events from an ETL file instead of a running process.
-scroll_toggle Only record events while scroll lock is enabled.
-scroll_indicator Set scroll lock while recording events.
-hotkey [key] Use specified key to start and stop recording, writing to a
unique file each time (default is F11).
-delay [seconds] Wait for specified time before starting to record. When using
-hotkey, delay occurs each time recording is started.
-timed [seconds] Stop recording after the specified amount of time. PresentMon will exit
timer expires.
-exclude_dropped Exclude dropped presents from the csv output.
-terminate_on_proc_exit Terminate PresentMon when all instances of the specified process exit.
-terminate_after_timed Terminate PresentMon after the timed trace, specified using -timed, completes.
-simple Disable advanced tracking (try this if you encounter crashes).
-verbose Adds additional data to output not relevant to normal usage.
-dont_restart_as_admin Don't try to elevate privilege.
-no_top Don't display active swap chains in the console window.
-include_mixed_reality [Beta] Include Windows Mixed Reality data. If enabled, writes csv output to a separate file (with "_WMR" suffix).| CSV Column Header | CSV Data Description |
