Best Project Zomboid settings for the AMD Radeon Vega 3 (Ryzen 3000U iGPU) (2026)

On a AMD Radeon Vega 3 (Ryzen 3000U iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Project Zomboid runs at roughly 24 FPS at 1080p with our optimized settings — up from about 18FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD Radeon Vega 3 (Ryzen 3000U iGPU) is a entry-level graphics card with 2GB of VRAM, and Project Zomboid is a relatively light game to run. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 24 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.

Across resolutions you can expect around 24 FPS at 1080p and 15 FPS at 1440p, dropping to roughly 8 FPS at 4K. Project Zomboid doesn't use upscaling, so the gains come from trimming the heaviest settings below.

💡 Project Zomboid: Isometric survival - almost entirely CPU-bound; Zombie Population is the biggest performance factor, not your GPU.
Recommended settings
Lighting QualityLow+10% FPS
Quality of the dynamic lighting model. The main GPU-side setting in this 2D isometric game (which is otherwise almost entirely CPU-bound).
Lighting UpdatesSlow+6% FPS
How often dynamic lighting recalculates. Normal is fine; lower it on weak CPUs.
3D ModelsLow+6% FPS
Detail of 3D character, zombie and object models (with a "Show 3D Objects" toggle). Lower it for a cheap gain.
Environment ReflectionsOff+5% FPS
Reflections on wet ground and windows. Cheap to turn off.
Puddle QualityOff+4% FPS
Rain puddle detail. A small, safe saving.
Texture CompressionOnbaseline
Compresses textures to ease VRAM use — leave on unless you run the 2x texture pack. The game uses very little VRAM.
