💡 Project Zomboid: Isometric survival - almost entirely CPU-bound; Zombie Population is the biggest performance factor, not your GPU.

At 1080p expect around 82 FPS, at 1440p about 62 FPS, and at 4K roughly 38 FPS with optimized settings. Project Zomboid doesn't use upscaling, so the gains come from trimming the heaviest settings.
