DLSS 5 Hands-On: Nvidia's Neural Rendering Pushes NBA 2K27 Toward Photorealism, at a Frame-Rate Cost

According to the ifanr account, the differences show up mainly in materials that usually reveal a game's synthetic origins. Skin no longer reads as plastic: light falls across players' faces with more complex transitions, and the eye sockets, nostrils, lips and ears pick up fine shading and subsurface effects. Jerseys gain a stronger sense of woven fabric, with more detailed shading inside folds and more realistic responses as cloth turns toward or away from light. Wooden courts keep their grain, scratches, wear and reflections, but the relationship between those details becomes more natural, closer to a floor that has been played on and lit repeatedly than to a high-resolution texture. Colors are also pulled back — the report notes that NBA 2K games have tended toward vivid, game-like tones, with the Los Angeles Lakers' court in particular looking overexposed, and says DLSS 5 reduces that effect.

The mechanism behind this is what Nvidia calls 3D-Guided Neural Rendering. Rather than asking developers to build ever more detailed assets and compute more lights and global illumination, the technology sits late in the graphics pipeline and applies a neural network to the frame the engine and GPU have already produced. That network receives not only the rendered RGB image but also motion vectors, temporal state carried over from previous frames, and masks and art-direction information supplied by developers, which tell it what is on screen. An appearance prior learned from large amounts of real visual data tells it what those things should ordinarily look like in the real world. The whole inference has to fit inside a frame budget of roughly ten-plus milliseconds, with neural rendering taking only a few milliseconds, which the report says is the reason a single-step model is used.

Performance remains the most immediate limitation. The report states that DLSS 5 currently requires RTX 50-series hardware in NBA 2K27. On the reviewer's RTX 5080, the game runs at 120 frames per second at 4K with maximum settings when DLSS 5 is off, and drops to around 45 fps when it is switched on, indicating considerable room for optimization.

The technology also does not suit every title. A sports game like NBA 2K27, which already aims for realism, benefits most; games such as The Legend of Zelda and Super Mario pursue their own visual languages, and teaching an AI what the real world looks like matters far less for them. The report suggests that if neural rendering becomes widespread, it may need to learn individual games' artistic styles, not just reality.

A further question concerns the line between realistic and faithful. Early DLSS 5 demonstrations drew controversy because the AI could make a face more lifelike while also pulling it away from the face the developer designed. The report says that debate largely faded once players saw the technology applied across games, including some released nearly two decades ago, which took on the appearance of visual remasters.

Seen against the industry's existing trajectory, the report argues that rising model complexity, asset detail and lighting accuracy have driven up production costs and hardware demands while delivering smaller perceptible gains. DLSS 5, it says, breaks the assumption that final visual complexity must grow in step with hand-built complexity — leaving NBA 2K27, as the first game to use it, at the start of that shift.
