Hi @Sailor139, Lol I am actually NE Indianapolis...
Not sure what features PRO2018 has, but to speed up the performance:
0) Never place a .plan file or a .layout file into a download folder, documents folder, temp folder or something similar. The software will scan every single file in a folder you placed your plan for textures. So I would create like a folder C:\ChiefArchitect\ProjectXXX. And place your plan there, and the software will only scan C:\ChiefArchitect\ProjectXXX and not a folder with a ton of files.
1) 3D > materials> Plan materials
Purge what you are not using, textures etc.
2) Sometimes "Camera View Set" layer picks up some bogus layers that you do not need to render in 3D.
In ALDO turn off the layers you do not think are relevant in your camera view.
Or create new layer sets: e.g. Camera View Set - Foundations, Camera View Set -3D etc.
3) Limit use of Paint or Texture on the top of existing Texture. So instead of a painter assign textures in Materials.
4) I literally have a 300M plan that renders on a computer with no Graphics card under 2 seconds, with countless textures and furniture.
5) Make sure that your system drive is not full ( i.e.70% is not good), because the software allocates memory on a swap.
6) If you have the memory 24G create a memory drive I recommend free ImDrive (8Gb).
Edit>Preferences> Folder>
Change Undo folder and temp folder to your memory drive.
You will notice that the UNDO changes will go nearly instantaneous in this software. And if you use SSD it will greatly extend the life of it.
Hopefully this will help.
