Best Cities: Skylines II settings for the AMD Vega 8 (Ryzen 5 2400G / 3400G iGPU) (2026)

On a AMD Vega 8 (Ryzen 5 2400G / 3400G iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Cities: Skylines II runs at roughly 36 FPS at 1080p with our optimized settings — up from about 12FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD Vega 8 (Ryzen 5 2400G / 3400G iGPU) is a entry-level graphics card with 2GB of VRAM, and Cities: Skylines II is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 36 FPS with FrameCoach's optimized settings, a clear jump from roughly 12 FPS with everything on High.

Across resolutions you can expect around 36 FPS at 1080p and 21 FPS at 1440p, dropping to roughly 12 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Cities: Skylines II: Big cities are limited by your CPU, not your GPU - upscaling won’t fix that.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
Cities: Skylines II supports DLSS and FSR. A free FPS boost - enable it first, though big cities are limited by your CPU, not the upscaler.
Global IlluminationLow+14% FPS
Bounce lighting across the city - one of the heaviest GPU settings. Medium is a clean trade.
VolumetricsOff+10% FPS
Volumetric fog and clouds. Expensive for the payoff - drop a notch for an easy win.
ReflectionsOff+8% FPS
Screen-space reflections on water and glass. Low is plenty in a zoomed-out city view.
Shadow QualityLow+8% FPS
Shadow resolution and range over the city. Medium is the value pick.
Level of DetailLow+7% FPS
How detailed distant buildings stay - also leans on the CPU. Medium for big cities.
Ambient OcclusionOff+6% FPS
Screen-space contact shadows between buildings. Low is a cheap trade.
Depth of FieldOff+6% FPS
Background blur when zoomed in. Cheap to turn off if you don't want it.
Fog QualityLow+5% FPS
Distance and weather fog. Low is fine for a clear city view.
Anti-AliasingOff+4% FPS
Edge smoothing across the cityscape. Cheap; leave it on to reduce shimmer.
Texture QualityHighbaseline
Surface sharpness on buildings and terrain - cheap on FPS if it fits your VRAM.
