S.T.A.L.K.E.R. 2: Heart of Chornobyl Update 2.0 releases today, August 20. A benchmark video from MxBenchmarkPC compares Unreal Engine 5.5 against 5.1. Frame rates improve significantly in CPU-heavy scenes like city areas and areas with many NPCs, while GPU-bound scenes show little change. The update also reworks vegetation, lighting, and terrain visuals.
Update 2.0 moves the game from Unreal Engine 5.1 to Unreal Engine 5.5.4. The benchmark video, recorded on an Intel Core i7-14700F with an RTX 5080, shows the largest frame rate jumps in city areas and locations dense with NPCs, where CPU load previously capped performance. GPU-limited scenes stay roughly the same.
Beyond frame rates, the update renews sunlight, shadows, and reflections outdoors, improves interior lighting, and reworks terrain and foliage. Light rain visuals are upgraded, and a new Fog weather mechanic limits vision and hearing for both the player and enemies, opening stealth options. The update also expands A-Life simulation, adds custom difficulty settings, three binocular types, four new weapons, new scopes, a PDA statistics page, and extends the Zone Kit mod tool.
