To improve FPS in Deadlock, start by testing Low shadows and fog, disabling SSAO, bloom and MBOIT, and trying FSR 1.5x or DLSS. Compare DirectX 11 with the current renderer and, where appropriate, cap the frame rate slightly below the monitor's refresh rate. This is a starting point for testing, not a guaranteed prescription for every PC. Players reported performance problems following the City Never Sleeps update of 29 September 2026, but the cause depends on the system and game build.
