The game uses both direct and indirect lighting, which creates breathtaking vistas with accurate bounce lighting powered by ray tracing. Reflections are also accurately rendered, updating with perspective changes, as seen in puddles and glass panes lined across makeshift houses.


As a dedicated fan, I’ve always been captivated by the hauntingly realistic post-apocalyptic worlds crafted by GSC Game World in their S.T.A.L.K.E.R. series. The team has put in countless hours to bring us S.T.A.L.K.E.R. 2: Heart of Chornobyl, a game we’ve eagerly awaited for years. Despite the challenges and obstacles that cropped up during development, such as delays and hurdles, the moment has finally come. Now, I can immerse myself in this chilling experience on my Xbox Series X/S and PC.

Utilizing Unreal Engine 5, S.T.A.L.K.E.R. 2 boasts some of the most stunning visuals in its category since it was first revealed. Now that we have the complete game, we’re eager to delve into the game and examine the specific elements to grasp how GSC manages such high-quality graphics on consoles. We’re also interested in understanding how these console implementations differ from those seen on PC, as well as analyzing performance, optimization, and other aspects.

Engine details

Back when I was eagerly awaiting, I was thrilled to learn that S.T.A.L.K.E.R. 2: Heart of Chornobyl would be one of the pioneering titles leveraging Unreal Engine 5’s rendering pipeline. Although the numerous setbacks prevented it from being one of the earliest games to hit the market using this engine, I can’t deny that it’s making fantastic use of its toolset to deliver visually stunning landscapes that hold their own against top-tier competitors in the genre.

In simpler terms, S.T.A.L.K.E.R. 2 showcases impressive applications of Unreal Engine 5 features such as Lumen for lighting and Nanite for geometry, among others. Employing a third-party engine like Unreal Engine 5 offers advantages in terms of optimization and cross-platform development challenges. However, GSC Game World has left some unpolished areas when it comes to performance optimization on PC, which we will delve into further later.

Test PC specs and PC Graphical Settings

In order to get the best experience while playing S.T.A.L.K.E.R. 2, it is suggested that players have at least a Ryzen 7 5800X or similar CPU, 32 GB of RAM, and an RTX 3070 Ti graphics card. For our testing, we ran the game on a setup featuring an AMD Ryzen 9 5950X CPU, Nvidia RTX 3080 Ti GPU, and 32 GB RAM – significantly more powerful than the recommended specs. Additionally, we installed the game onto a PCIe 4.0 NVME SSD to ensure fair comparison between the PC and Xbox Series X versions during our tests.

Kicking things off by checking out the settings right away, S.T.A.L.K.E.R. 2 offers an array of adjustable options to strike a balance between smooth gameplay and high-quality visuals. However, it’s important to note that the settings menu itself is quite basic. Unfortunately, it lacks specific details like VRAM usage or visual examples to help clarify the impact of each setting available.

The game provides flexibility for enhancing visual quality through technologies like AMD’s FSR 3, Nvidia’s DLSS, and Intel’s XeSS, along with frame generation settings. For our test runs, we set everything at the highest possible setting (Epic) in native 4K resolution. We configured DLSS upscaling to Quality mode, which reduces the internal rendering scale by approximately two-thirds (66%).

PC Performance

Initially running the game on your computer requires about a minute for the shaders to be processed. Similarly, loading periods may last approximately 20 to 30 seconds, which is relatively long for a modern-day exclusive title.

Regarding the real-time gameplay, S.T.A.L.K.E.R. 2 is visually stunning, a point we’ll delve deeper into later. The details, from the vegetation to the characters and visual effects, are impressive. However, this high level of detail raises performance concerns as well.

The recommended hardware specifications allow the game to target 1440p at 60 frames per seconds. But our test build was able to max out everything at Ultra at 4K with DLSS in Quality mode. We observed frame rates around 40 to 60fps depending on how taxing the effects were. Having VSync and frame generation options may make things a lot smoother, but as far as our build was concerned, we are okay with the performance and given there is an option to lock the frame rate to 30, lower end hardware might be able to run the game at a stable frame rate.

Xbox Series X Performance

On the Xbox side, we have two unique options: Graphics and Performance. Opting for Graphics mode maximizes all the visual features in a 4K resolution, making everything look stunning, from textures to post-processing effects. However, it may not run as smoothly since the frame rate is limited to 30fps, and there can be some inconsistencies that might detract from the overall experience for certain players.

In Performance mode, the picture quality and special effects are reduced, but the frame rate increases to 60 frames per second. Having more frames significantly improves smoothness, particularly during battle scenes. This is generally the optimal way to play S.T.A.L.K.E.R. 2 on a console, despite some issues with texture pop-in and level of detail adjustments that might seem surprising given it uses UE5’s built-in Nanite for world streaming. However, overall, the game functions well in its main aspects.

One way to rephrase the given text in natural and easy-to-read language could be:

A Graphical Behemoth

To begin, let’s talk about the character models in S.T.A.L.K.E.R. 2. These models are incredibly detailed, thanks to advanced rendering techniques that make them look remarkably lifelike and animated smoothly. The high polycount and meticulously designed skin meshes give them a realistic appearance, while their hair has fine strand textures with minimal imperfections along the edges.

In addition to that, the game S.T.A.L.K.E.R. 2 boasts an impressive lighting system. It employs a Lumen-based solution to cater to both direct and indirect lighting, which contributes significantly to the game’s visual appeal. The global lighting and indirect lighting work harmoniously to produce stunning landscapes with lifelike bounce lighting, thanks to ray tracing. Moreover, reflections are equally precise and adaptive, updating seamlessly as your viewpoint changes. You’ll notice numerous instances of this in the form of puddles scattered on the ground and glass windows on temporary structures.

In addition to GSC Game World, the game engine for S.T.A.L.K.E.R. 2 employs technology called Nanite to create visually stunning landscapes with an impressive level of geometric intricacy. The environments in this game are typically constructed from various elements such as rocks, buildings, and vegetation, all crafted using premium materials. Furthermore, the use of Nanite helps resolve problems related to Level of Detail (LOD) switching and world loading, and S.T.A.L.K.E.R. 2 demonstrates exceptional performance in managing these aspects effectively.

Afterward, we have a series of processes that follow, often referred to as the post-production stage. This stage includes a variety of top-notch visual enhancements designed to make images more appealing visually. These include abundant use of volumetric smoke, fog, and smoke volumes, as well as high-quality motion blur and depth of field effects. Additionally, alpha particles are utilized in combination with flames and weapon effects, adding a further layer of realism to this comprehensive post-production pipeline.

Xbox Series X vs PC 

As a gamer comparing the Xbox Series X and PC editions head-to-head, I’ve noticed that visually, there isn’t a significant gap. They both employ similar techniques for their presentation, boasting identical texture implementations, Lumen for lighting, and Nanite for world generation – just to name a few. The key disparity lies in the quality of these visual effects, with the PC version often offering a more refined experience due to its higher performance capabilities.

It’s not surprising that Xbox’s high-quality mode is very similar to our PC version, although the PC version offers slightly better image sharpness. Textures are a bit clearer, and the world streaming works more smoothly in the PC version compared to the console release. Reflections and post-processing effects are quite comparable between both versions.

As a gamer, I’ve noticed that when I switch to Performance mode, the game’s resolution takes a hit, which definitely affects the image quality. The anti-aliasing does a decent job of enhancing the visuals, but it can’t compare to the PC version. Textures become less detailed and sometimes appear blurry or ‘muddy’, and effects like fire and particles don’t look as vibrant or crisp as they do in other versions of the game.

Conclusion

GSC Game World’s S.T.A.L.K.E.R. 2 showcases impressive graphics, skillfully utilizing Unreal Engine 5’s array of tools to depict a hauntingly realistic post-apocalyptic landscape. The integration of Lumen and Nanite has some minor flaws like texture pop-in, but the overall effect is stunning, offering a genuinely immersive experience. However, there are performance challenges in both versions, suggesting that load time optimizations and reducing shader compilation time on the PC version could enhance the gameplay further.
