[Switch] Low FPS with GUI open

Jan 9 edit: Please note that I posted this in the switch feedback thread, as I see this is general feedback and not something I need support with. I’m on default settings and on a console. It looks like it was moved here.

I've been playing the Switch port since release and overall it's been great! One thing I've noticed is that I always get a significant FPS drop with the Character menu open, or when my cursor hovers an entity that generates a frequently updating tooltip. Basically, it seems like having interface elements on the screen significantly impacts performance.

E.g., in a test base for a nuclear plant, I get solid 60FPS/UPS when zoomed out to the max and with smoke disabled. If I hover over a turbine, that drops to 47/60 FPS/UPS. If I then press X to bring up the character menu while still hovering over that turbine, that drops even further to 28/60 FPS/UPS.

As mentioned, that's with smoke disabled. But for bug reporting purposes I also used the red "reset" button in both the Graphics and Interface menus to go back to all the default settings. With default settings, FPS/UPS with nothing selected, when hovering over a turbine, and when hovering over a turbine and opening the character menu are 43/60, 33/60, and 24/60 respectively.

Note: all tests were performed docked and UI scaling is still automatic. FPS/UPS numbers are from turning on show-fps in the Debug settings window (which as a side note, related to this performance report, having the debug settings window open drops the smokeless FPS from 60 to 53)

I took some screenshots of the scenarios I described previously with debug render time info turned on. They are attached to this post

These are known issues and not much can be done about it unfortunately.
The character GUI has many slots, icons and numbers that when drawn take a long time. This is generally OK as a framerate of ~30FPS is enough for navigating GUIs.

Ah oh well, thanks for responding Twinsen! I originally posted this in the Switch feedback thread just because I hadn’t seen it mentioned elsewhere, but didn’t intend it to be more pressing than just another post in that thread. I’m still impressed at how much you were able to make the Switch handle!
