If using Linux, ensure wine is updated to version 9.0+ and that fonts-mscorefonts are installed. | Optimizing CityDom v03 for Performance A successful install is just the beginning. To truly harness CityDom v03, apply these optimization strategies. Memory Paging Tuning Because v03 streams assets continuously, set your Windows page file to a fixed size of 1.5x your RAM (e.g., 24 GB fixed for 16 GB RAM). Place the page file on the same NVMe drive as the installation. Shader Compilation Cache The first time you load a new biome (e.g., switching from “Alpine Valley” to “Mangrove Delta”), expect 3–5 minutes of shader compilation. Do not interrupt this process. After compilation, the cache is stored permanently, reducing subsequent load times to under 20 seconds. Mod Conflict Scanner CityDom v03 includes a built-in --scan-conflicts command line argument. Open a terminal in your install directory and run: citydom v03 by city dom install
