DLSS 4 marks a significant advancement in upscaling technology.  By transitioning from a CNN to a Transformer model, DLSS 4 delivers noticeably clearer visuals when enabled.  This improvement is evident in comparison screenshots from games like Warhammer 40K: Space Marine 2.

Remarkably, the performance mode in DLSS 4 generates crisper images than the quality mode in DLSS 3.  This allows gamers to achieve high frame rates without sacrificing visual fidelity, eliminating the need to compromise.

The new Transformer model dramatically elevates DLSS image quality.  Compared to the previous Convolutional Neural Network (CNN) architecture, this model analyzes a greater number of sampling parameters from rendered frames. This provides DLSS with more data for image upscaling, resulting in fewer ghosting artifacts, smoother edges, and improved motion resolution.

This innovation also enhances complementary RTX technologies, such as Ray Reconstruction. This technique makes ray tracing more efficient on smaller details, reducing visual artifacts and noise.

Impressively, this is only the first generation of the new Transformer model.  Nvidia invested six years refining its CNN model, so we can expect continuous improvements to DLSS image quality in the coming years. This exciting advancement is available to all RTX GPU users (20, 30, and 40 series).

Over 75 games will be compatible with DLSS 4 on the launch day of the RTX 5090.
