Previously, only sunlight could naturally illuminate environments, limiting the tech’s usefulness in many of the game’s locations.
In the Metro Exodus PC Enhanced Edition, 4A Games has completely overhauled RTGI, introducing a new generational leap in image quality and immersion that finally rivals that of Hollywood’s biggest blockbusters.įor starters, all shadowed lights in the game now contribute to ray-traced global illumination. Compared to the game with ray tracing disabled, the difference in quality was staggering, giving players their first taste of next-gen gaming.

With ray tracing, powered by GeForce RTX GPUs, 4A Games introduced gamers to ray-traced Global Illumination lighting (RTGI) in Metro Exodus, simulating how light naturally floods in through windows and damaged surfaces, brightening interiors. However, each solution had a compromise, and no matter how many effects and workarounds a developer combined, none could approach the quality and realism of the ray tracing seen in animated movies and Hollywood visual effects. Prior to the introduction of real-time videogame ray tracing in 2019, when GeForce RTX GPUs launched with dedicated RT Cores that enabled ray tracing at playable frame rates, game lighting was achieved with a slate of ingenious and inventive rasterized hacks. Gone are rasterized lighting fall backs and clever hacks - now, all lighting is calculated in real-time with superior accuracy using ray tracing, necessitating the use of a GeForce RTX graphics card for NVIDIA gamers. In the two years since 4A Games pioneered the use of real-time ray tracing, new research, tools, and middleware have led to massive strides in image quality and performance, inspiring the team at 4A to create a new, upgraded version of the game entitled Metro Exodus PC Enhanced Edition.įree to everyone who already owns Metro Exodus, the PC Enhanced Edition primarily improves lighting by introducing a suite of new, ray-traced dependent features.
Metro 2033 featured a raft of 2010-era cutting-edge tech, including DirectX 11 tessellation and GPU PhysX acceleration, 2013’s Metro: Last Light improved upon everything while making great strides in the fields of environmental destruction, post processing and particle effects, and 2019’s Metro Exodus was one of the first games to implement real-time ray tracing and NVIDIA DLSS, kick starting a new generation of gaming. 4A Games’ three critically acclaimed Metro games each pushed the limits of PCs at the time of their release, utilizing the latest technologies to ramp up immersion and image quality, and to enhance gameplay.
