New PresentMon API support in RTSS

[AlexUnwinder]

Just FYI,

New PresentMon API based data provider and GPU busy metric support will be available in the next version of RTSS OverlayEditor plugin:

Cool, thanks for the heads up!

Do you want me to add RTSS to the list on the readme? If so, just let me know a good link to use (or PR it for me).

Sure, why not. Official home product page for RTSS is https://www.guru3d.com/files-details/rtss-rivatuner-statistics-server-download.html (please take a note that the build with new PresentMon SDK integration is not publicly released there yet).

RTSS 7.3.5 beta 3 build 27699 with PresentMon integration is released, download link is available in this post:

Fastest way preview it is to load one of two built-in PresentMon based sample overlay layouts:

• Launch RTSS
• Go to Settings -> plugins tab -> Put checkmark next to OverlayEditor.dll plugin to activate it then double click the plugin or click "Setup" below to open the editor
• Inside the editor go to Layouts menu -> Load -> select presentmon_frame_scale.ovl or presentmon_time_scale.ovl

And an example of using it to display realtime CPU/GPU bottleneck indicator in overlay:

In this example I see present mode change from composed-flip to hw-independent-flip at about 14s, but a decreased frametime isn't displayed until around 30s. Is the data lag getting that long or is something else going on here?

Decreased frametime which started around 30s is a result of toggling framerate limiter off with a hotkey. I used it to simulate switch from CPU limited to GPU limited workload and show how "Limited by" indicator works.

I wonder, how do I monitor PCL, like in this video (total render latency, not just frametime)?
