Hello there @Leon_Flynn!

Checking through your log, and considering the “NvPresent64” call, plus the flickering you are seeing, this is most likely a driver’s conflict with nVidia.

I strongly suggest a full cleanup using the DDU tool, then installing the latest version of the Studio drivers, instead of the Game Ready version, as the Studio ones are best suited for engine work.

Now, if the issue remains active even with those new drivers, then the next thing I would check, are your active overlays. There’s a history of conflicts between UE and certain overlays, specially Discord’s. Look for any of these in your system, and disable them.

Finally, if you still encounter any flickering, I would try disabling HAGS from Windows, the other usual cultrip for cases like this. To do so, go to System > Display > Graphics > Advanced graphics settings, and switch off Hardware-accelerated GPU scheduling. Remember to restart your system to apply the change.
