Portal with RTX Update: Now With DLSS 4 & RTX Neural Radiance Cache

Today, Portal with RTX is being upgraded with DLSS 4 with Multi Frame Generation, multiplying framerates, as well as the transformer model for Ray Reconstruction and DLAA, enabling even better image quality. Portal with RTX is also adding RTX Neural Radiance Cache (NRC), a neural shader that improves indirect lighting, as well as a bevy of performance optimizations.

Release Notes:

• Added DLSS 4 with Multi Frame Generation, and the new AI transformer models for DLSS Ray Reconstruction and DLAA. RTX 50-Series owners can now multiply framerates with 3X and 4X modes, generating up to 3 additional frames per rendered frame, while all RTX users can experience the transformer model for Ray Reconstruction and DLAA to elevate image quality with greater detail, improved stability, and reduced ghosting. To activate DLAA, navigate to the advanced graphical menu and choose “Full Resolution” in the DLSS mode menu.
• Added RTX Neural Radiance Cache (NRC), a neural shader that leverages neural networks to estimate indirect lighting more accurately and performantly. With NRC, fully ray traced lighting not only looks better but is more responsive as well. NRC features multiple quality levels, each automatically selected based on the graphical preset being used. NRC quality levels can also be manually adjusted from the advanced graphics menu under the “indirect illumination” options.
• Added a new texture streaming system that optimizes VRAM usage to maximize texture quality within the available video memory budget
• Made various performance improvements and memory usage optimizations
• Changed the behavior of default graphical presets.
• Optimized RTX Remix’s shader compilation process, reducing shader compilation time. Also added an on screen notification when shaders are actively being compiled.
• Updated NVIDIA Real-time Denoising (NRD) library to 4.13 for better performance, as well as sharper and more stable denoising
