The poly count on the medieval houses is pretty high compared to other tilesets, on the other hand it is pretty low compared to some of Lord of Worm's tiles, so I guess that is not what causes the lag.
The textures however could cause the lag if you use the NWN2 houses. They had 1024x1024 textures for a building which contained all the textures for that building and some of the textures were only 128x128 which was too small for more detailed textures, so when I retextured the buildings, I increased the size of many of the textures to 2048x2048.
Also the tileset as a whole is becoming too big. I started this tileset as a tileset with houses from NWN2, but now those are just a very small part of the tileset.
This is my first attempt at creating custom content and as you can see I started with things that already existed (the NWN2 houses) and just retextured them and added walkmeshes and doors.
Then I started adding Bioware tiles and changing them. There were a lot of tiles that were like 50% made by me, but still nothing I made from scratch.
If I had to make this tileset again, I wouldn't use any of the flat tiles from the Bioware tilesets, but back when I started I had to do that because I couldn't make terrain that wasn't flat.
I think about putting the city tiles without the NWN2 buildings and the DLA buildings in a separate tileset which will only have the medieval houses I made myself plus the city walls and castle tiles which are based on the DLA tiles, but which I changed a lot. Then the walls from the Castle Construction set and the terrain types that are needed for the city tiles I made, like water, grass and pit. For cliffs behind the city walls I will make a cliff terrain myself rather than using the cliffs from the Bioware forest again.
I hope a medieval city tileset will run alot faster because it will only use 512x512 textures and it will be a lot smaller. The poly count however will still be rather high, but I already removed so many details from the houses that I don't want to remove any more. The beams used to have rounded corners and the like and I changed them to simple boxes.
I'm not sure if the poly count is really a problem though. In Lord of Worm's forests there are tiles where the many mushrooms alone have as many polygons as one of my houses and they don't cause any lag.
So if you want to use this tileset for building a city and you don't need the NWN2 houses, maybe the separate tileset will work for you.
Something else I could do would be taking the NWN2 houses apart so that there is a mesh for each part that uses a different texture and not one for the whole house. Then I could use lots of 256x256 textures. But taking those houses apart would take forever and a day and I don't really feel like doing that
