Hi! Sorry for my so late respons and thank you for your full answer.
For me it will be nice to "disable all camera/overlay" in HDR cause SDR webcam is useless in HDR mode and overlay on its own take some FPS (1-3).
Happy to use your program!

And sometimes FPS drop (5-10) in SDR too. In some games I must turn off SLI completely to stabilize FPS WITH Action! (without your program everything ok, non fps drop).

Answer to my question: It's just PQ10 (not HDR10).

Action! said that HDR is HDR10. Question: This is really HDR10 (with ST-2086) or just PQ10 (only standard ST-2084) without static metadata? This is not a big problem for me (maybe not at all) just curiosity.
Thank you.

Log: In HDR SLI recording - not recommended, performance might be lower then in non-SLI mode. Will you fix this? Can it be fixed?
Once again thank you!

Yes! Thank you! Now, please support SLI for HDR And Action! will be beautiful.

Fullscreen. RE 2 HDR mode works only in fullscreen.

The same problem with Resident Evil 2 Remake! I tried to explain this to Mirillis's staff! I dont know what to do

RE 2 in HDR and my screen is HDR, but when I turned on Action! the game colors washed out. Here another video from my phone: https://drive.google.com/file/d/1N5y31C ... sp=sharing
Just look at it, please.

Well, I saw log for new verison and have to ask: Will be SLI support for HDR in upcoming versions? SLI scaling is very important for 4K recording.
And RE 2 (DX 11) is still a problem. Nothing changed.
Thank you for support!
