Introduction

DLSS 4 introduces a major leap in image quality and performance. It isn't just a version bump featuring Multi Frame Generation, but introduces updates to nearly all DLSS sub-features. DLSS from its very beginning relied on AI to reconstruct details in Super Resolution, and with DLSS 4, NVIDIA is introducing a new Transformer-based AI model to succeed the Convolutional Neural Networks previously used—for double the parameters, four times the compute performance, and significantly improved image quality. Ray Reconstruction, introduced with DLSS 3.5, also gets a big image quality update with the new Transformer-based model.



In this article we will look at the improvements the DLSS 4 Transformer model brings—specifically focusing on the improvements for owners of older GeForce RTX cards: GeForce 40 and older.


Transformer-based Super Resolution in DLSS 4 significantly enhances detail retention. Some examples include higher fidelity in textures, such as the bag's intricate patterns. Smarter models help improve image quality for heavily used features like Ray Reconstruction and Super Resolution.

Image Quality

Below, you will find comparison screenshots of Cyberpunk 2077, Alan Wake 2 and Stalker 2: Heart of Chornobyl at 4K, 1440p, and 1080p resolutions, showcasing different quality modes for DLSS Super Resolution CNN and Transformer models, FSR, and XeSS. Screenshots for TAA, DLAA, DLSS Frame Generation and DLSS Ray Reconstruction are also available in the dropdown menu. For a dynamic view of these technologies in motion, watch our side-by-side comparison video. This video reveals issues such as shimmering or temporal instability that might not be evident in still images.

All tests were conducted using a GeForce RTX 4080 GPU at Ultra graphics settings with Path Tracing enabled in Cyberpunk 2077 and Alan Wake 2. We also used a GeForce RTX 3060 and GeForce RTX 3080 for additional testing. Motion blur, depth of field, film grain and chromatic aberration were disabled for better image viewing.
