Up to double the gpu usage in this particular tavern.
Location: Daggerfall, Chesterwark

I've tested this on: 0.13.5, 0.13.4, 0.13.3, 0.13.2, 0.13.1, 0.13.0, 0.12.3, 0.12.2, 0.12.1 & 0.12.0
Before every test I deleted "AppData\LocalLow\Daggerfall Workshop\Daggerfall Unity" Folder
No mods were used/active or present what so ever

I discussed this in PMs with Magicono43 on Discord. They discovered that there is over double the lines in the dumpbuilding json compared to another tavern. I have attached the json files for comparison.
They also suggested that it may be due to duplicates within this building.
