This approach has been around for some time, yet it never made it into mainstream games. While CPU ray tracing offers strong performance, it falls short compared to modern hardware like RTX. Remember that Screen Space RT can't replicate the depth and realism of true ray tracing. The method relies solely on what's visible on the screen, so it can't simulate reflections from objects off-screen. Likewise, lighting appears less precise since it makes general assumptions about scene elements due to limited data. Unlike newer solutions, it doesn’t perform full intersection tests or access detailed object properties—just position, normals, color, and specular values per pixel. Because of this, it can't execute ray tracing accurately like RTX does. It skips triangle-based checks and instead uses gbuffer data, attempting global illumination through approximations. Many developers notice it exaggerates outdoor scenes, which makes sense given typical lighting practices in games. Issues arise with volumetric effects like fog or water, as the shader doesn’t understand their unique treatment needs. This limitation means it can’t fully replicate realistic environments. If you want quality results, consider alternatives that offer richer data access.
Shadow of Tomb Raider combines ray tracing with a screen-space technique. It delivers impressive visuals but still feels somewhat artificial. The RTGI system also supports material recognition based on surface texture, enhancing realistic light reflections. Even with screen-space ray tracing, it becomes clear how significantly lighting in games has improved compared to earlier methods.
Shadow of the Tomb Raider leverages RTX technology. The claim about using screen space ray tracing for global illumination is inaccurate. If it relied on that method, the hardware wouldn't handle it efficiently since it doesn't employ the same process. Instead, it utilizes ray tracing—often called ray casting—in screen space to determine reflections. This approach is familiar in gaming for visibility checks and has been used for years. It differs significantly from RTGI, which handles global illumination through screen space techniques like contact shadows, but not via ray tracing. Ray casting simply sends rays from one point to another, checking obstacles without complex shading or material analysis. It avoids intricate lighting calculations after hits, making it much faster. This is why "ray casting" is the standard term—accurately describing its function. The game also incorporates other screen space effects for fake global illumination, but RTX-enabled lights are excluded from this method.
They are upset because it's now called "Can it run Cyberpunk" instead of Crysis, leaving them with no choice
It clearly mentions screen space reflections in the settings. You’ll notice this effect by adjusting the camera position; water distortions appear oddly at the edges, which shouldn’t occur with full ray tracing. Shadows also behave strangely, getting cut off at certain angles since mountain peaks are outside the visible area and shift as you move the camera. Reflections and global illumination can only be accurately rendered within screen space, even though it might cause minor glitches. Fortunately, these issues are uncommon and most players won’t even notice them—they’re used to seeing rasterized reflections alongside ray-traced ones. I can easily tell the difference. It seems they added ray tracing and global illumination on top of the existing rasterizer. Since the game originally launched without ray tracing, it makes sense they integrated it later. Still, the visual quality remains impressive, though with some minor artifacts. The main advantage is that reflections and shadows stay perspective-accurate, something RTGI can’t achieve due to its limited depth buffer access.
Dude, did you check past the initial words of my message? I mentioned this in the second paragraph! If you think I'm mistaken, please make sure you've fully read what I wrote. But as I explained before, screen space reflections are handled quite differently in Shadow of the Tomb Raider compared to RTGI, so you shouldn't assume one version is better than the other. Yes... and no. The way it actually functions is this: RTX combines rasterization with ray tracing for global illumination and reflections, which are then added on top before being sent to the display. (Only fully path-traced games use ray tracing directly—like Minecraft and Quake 2 RTX.) Saying it’s just tacked on above the rasterizer isn’t accurate. Rasterization doesn’t create the final image instantly; it slowly assembles it using many layers of data. Each frame might need over ten layers, one of which comes from RTX. Modern games don’t render everything at once—this is how things are now. For Shadow of the Tomb Raider, you’ll typically see these stages: Spoiler Depth → Depth Normals → Albedo → Ambient Occlusion → Shadow pass (RTX) (if enabled) → Screen space reflections → Volumetric lighting → Hair rendering (requires several passes) → Exposure and tonemapping (HDR/SDR) → Lens flares → Bloom (needs many passes) → Antialiasing → Motion blur (depends on movement) → UI pass for mud, snow, rain (not calculated in this order) Screen space reflections are just one layer among many. They’re part of a deferred shading method, meaning reflections are computed after most other elements are done. This is crucial because reflections copy specific parts of the scene onto reflective surfaces. If you ran the UI pass first, the result would be completely unclear by the time motion blur was applied! RTGI adds another layer too, but it always finishes last in the process. That’s why Shadow of the Tomb Raider handles these effects more smoothly. The technique relies only on screen-space buffers and follows a proper rendering sequence—like building a house from the ground up instead of starting with the roof.
You're adding too many elements and using the term "RTX" as a catch-all label. RTX really refers to RDNA architecture or DXR/DXV tech, but both are essentially just RT in short. Your praise is a bit overstated. There are plenty of cases where things don't turn out as intended, and Shadow of Tomb Raider exemplifies that. It often feels like components are forced together rather than naturally integrated. This approach reinforces the idea that it's not perfect from the start.
Technically, the game struggles with rasterized reflections clashing with ray-traced elements, missing offscreen data, and sometimes crashes before you even reach the main menu. It looks decent at native 1440p but falters with puzzles involving light rays that appear low-resolution and blocky. Shadows also seem inconsistent, often rendered at lower resolutions than intended.
Compared to other titles with RTGI, this one falls short in realism, especially when ray tracing is enabled. While it does make some noticeable improvements over older versions, the visual quality remains limited by its technical execution. I find it more appealing to stick with games that handle lighting and reflections more naturally, as they offer a more immersive experience.
