Tested this config on my machine (Thinkpad E14 with Fedora 42) and it made a worlds difference!

So for me this tweak makes it much snappier and smoother, but @Levev for example had very weird lags and artifacts after it, so it still remains to be tested by others, feedback welcome.

DWMFRAMEINTERVAL seems to be the minimum frametime for RDP, i tested with it set to 8 and using
Get-WmiObject win32_videocontroller | fl CurrentRefreshRate,MaxRefreshRate,MinRefreshRate seems to support that assumption: it reported the max framerate for the RDP device as 125.

so DWMFRAMEINTERVAL would ideally be set based on the users display not just always for 60fps.
that would require setting the registry every time the user boots the container, and might lag by 1 boot, so it might be better to just set it high by default.
i'm not sure if freeRDP does a good job auto negotiating based on the clients framerate so im not sure if it would always try to run at max

Just tested it on nixos on my laptop after fiddling with a shell.nix for an hour. RDP runs much smoother and is very noticable. Hopefully it can be merged soon into main!

Same experience - also NixOS user. Much, much smoother performance!
