Thanks for the clarification. I'd suggest that we not try and solve that problem until we have someone who needs it? What I'm using this extension for is to correlate GPU times with WSI times as required by the GOOGLE_display_timing extension. That extension reports the time gap between the end of rendering and when a frame is displayed as reported by the WSI backend, so I needed some way to translate between those two time domains. To do this, I call this new function once per presentation, which means I'm getting recent values for both clocks which should track any minor clock skew. -- -keith
