I have a very large base (100x science multiplier) where every bit of performance matters. Nowadays I mostly work from map view, but going into map view (looking at the same location with the same zoom) causes ~1.7ms of update time continuously, which is already 10% of the available budget. Since I can't understand why this would be the case I report this issue here. Game render preparation goes from ~0.3ms to ~2.0ms

Re: Performance in map view
Remote view has more work to do as it tries to render both the world view (for areas explored by radars) and the map view. But the way it works is: map view always runs but then decides for each chunk in view if it should obscure the world or not.
So if you have any map view options enabled (the icons on the right side when zoomed out) all of them take time since it has to check which of them might apply to what you’re seeing.
Essentially, remote view will always take more time than simple world view or simple map view as it’s both at the same time. Disabling map view options may help.

Re: Performance in map view
I did some testing, and you are right, disabling all map view options did help. Unfortunately it's difficult to live without ALT-mode in map view, and that option was responsible for the largest part of the extra update time.
Really sad that I have to pay that performance cost even when zoomed in like in normal view.

Re: Performance in map view
Alt mode itself should not cause issues: but pressing alt in map view does toggle some of the map view options so that may be a factor.

Re: Performance in map view
Maybe alt-mode was the wrong technical term, I meant the recipe icons in map view. They make such a huge difference when trying to visually find stuff, so I don't really want to disable those.
Unfortunately they cost performance in map view even if zoomed in and I don't see a single one of those icons on screen. The time spent makes me think that the game actually renders all recipe icons (30k or more in my save), which is nuts if zoomed in.
