Speed up interfaces with 2D zones with millions of elements (make it a multicore process)
The interface for large 1D-2D models is very slow. While moving through the geoplan every time it takes about ten seconds to load and show the location. We noticed that in this time only 1 of the 32 CPU is used for 100%. We tried 2 complete different videocards (Quadro K2000 vs Quadro M6000 24GB) but that did not make any difference (both slow). The interface/geoplan works fine when we do not display the 2D zone. We tried lot of things that were suggested by your supportdesk, but it seems like that this is something that will only really improve if the underlying process uses more resources (cores).

We experienced this issue with larger models (6 mio cells +) as well.
Suggesting to significantly improve the rendering performance of the 2D elements in the GeoPlan.
There are a number of options that can be taken in the properties and themes dialogues, like reducing the graphic quality, but it does not improve much.
Applying different zoom levels could help in this context...In our case, a powerful machine is used (Quadro RTX 24 GB, SSD, 128 GB Ram).
According to support, "this process uses only one thread, perhaps disabling hyprethreading can improve performance."We suggest looking at "progressive rendering" / "active window boundary limitation".
The requirements for the modellers dealing with larger mode,ls stress the need to allow efficient Geoplan panning for larger and complex models. In particular the panning performance around and beyond the current technical 2D elements limit around 30 mio cells.Improving this would make the modelling much more efficient.
