I don;t think I mentioned this but we are using the latest test version of Enscape. I tend to use these releases since I have not really experineced any real issues with them while I get to play around and experience the latest goodies.
I think the best way you can go now is to try the latest stable release 2.5 to see if it works more stable. Preview versions are work in progress, especially now with RTX.
You are also welcome to send feedback (followlink my post signature) including logs, so we could check if Enscape is responsible for reduced resolution - we do it when FPS drops low. It will help us to tweak performance before the next release
Please also mention your forum name so we could map the feedback to this thread.
