The option that appears in the new version 1.22.0,
NEW FEATURE: Adaptive / Variable framerate video recording does not appear any lake. It is not any error or where to find it and activate it.

The tests still give me all with constant framerate AVI or MP4 with NVENC.

As this option is enabled?

Variable frame rate is not the same as bit rate. This option was made to lower the possibility of broken videos where user computer performance is not able to encode the video with selected settings.

I think i understand the point now. I was test-recording single player in Left 4 Dead, and wouldn't u know it de-synced audio from video as i watched it. It was caused from the random slow-motion style effects that occured for some odd reason, i was recording at 30 fps.

I was disappointed at first of course, but then i noticed it was in sync again after a few seconds. My guess is that Action now sort of "feels" the frame rate and adapts to it so to speak, in an effort to "re-sync" it. At least that's what i ended up thinking.

If that's the case, then it's yet again a great update! Though there's also a downside to this: if my game shows ALOT of de-syncing, it could take longer to "re-sync" it. Hopefully that won't happen.

Yes, I got confused in the last sentence, but I think the option should be able to select. Shadowplay it always encoded in VFR and no problems except when you edit the video, but apparently Sony Vegas editing it well.
