Official troubleshooting sequence

1. For low FPS while paused, lower the graphics preset, resolution scale or output resolution. 2. Close background tasks; check laptop power settings and connect power. 3. Update graphics drivers. 4. Inspect CPU, GPU, RAM and VRAM usage. High VRAM pressure suggests lowering textures; sustained GPU saturation suggests graphics/resolution changes. 5. If individual CPU cores are saturated and increasing simulation speed has little effect, reduce simulation load such as population/town count when choosing a new map.

Identify the symptom first

Compare paused rendering with the simulation running, then note the graphics preset, output resolution and resolution scale. Observe actual CPU/GPU/VRAM usage before identifying a bottleneck. Change one setting at a time and record the result; this site supplies no invented benchmark.

Patch and platform status

Steam rendering and VRAM improvements are documented, with no measured FPS gain. Steam Stable 40420 is documented on October 8, 2026. The PC notes do not confirm that Epic/GOG or consoles received the same patch. Their latest numbered official entries and the announced rollout are displayed separately. Check the installed build in the main menu; a manual or support source check is not an independent live-build test.

Data safety and unresolved causes

Cause-specific confirmation and device-specific success remain Unknown. Before reporting, record the store/platform, installed build, operating system, hardware, mod versions, affected save and exact reproduction steps. Keep the relevant stdout.txt and crash files before another launch overwrites them. Use a copy of a save for diagnosis and the official support form for unresolved failures; no successful reproduction or guaranteed remedy is claimed here.
