NVIDIA DLSS 4.5 introduces 6X frame generation and second generation transformer AI for RTX 50 series to enhance 4K performance and image quality
The GeForce RTX 50 Series received its first DLSS 4.5 update from NVIDIA on March 31 2026. The update introduces a second generation transformer AI model which establishes a new framework for rendering and scaling frames. Users can now access these features through the latest beta version of the NVIDIA app provided they have installed Game Ready Driver 595.97 or a more recent version.
The Automatic Transmission for Performance uses Dynamic Multi Frame Generation as its core function. The system operates using Dynamic Multi Frame Generation as its primary function for this update. The previous frame generation system worked with a dedicated multiplier. The new DLSS 4.5 system operates as an automatic transmission which controls your graphics card performance. The system now monitors the gap between your hardware output and the maximum refresh rate of your display in real time. The system automatically adjusts multipliers to match gameplay needs for 144Hz 240Hz and higher refresh rates.
The system increases frame production to handle high intensity scenes when GPU performance reaches its limits. The system uses its lower workload mode to improve image quality while reducing latency. This technology lets fast refresh OLED gaming displays function at their highest capacity while preventing processing waste from unnecessary frame generation.
The frame generation multiplier for GeForce RTX 50 Series GPU users now reaches its highest value of 6X. AI systems now possess the capacity to produce five synthetic frames for every frame the game engine displays in actual gameplay. The March technical data shows that 6X mode achieves a maximum performance boost of 35% in high demanding path traced games at 4K resolution when compared to 4X mode.
NVIDIA uses Reflex technology to achieve low latency performance for its high multiplier needs. The combination enables users to experience fluid motion on 240Hz and 360Hz displays while maintaining decreased input delay. The Fixed mode remains available for competitive games which lets users pick their preferred multiplier instead of using dynamic scaling.
DLSS 4.5 Super Resolution now employs a transformer model with five times the compute power of the original version. The fundamental change affects how the AI processes lighting information. Earlier models produced muted colors because their logarithmic space operation caused shadow details to be lost. The new 4.5 model infers directly in linear space which is the native ground truth of the game engine. The system delivers neon lights and reflections which maintain their original color characteristics and accurate physical dimensions.
The update provides solutions for the majority of visual artifact problems which occur in visual media. Ghosting on fast moving objects has been drastically reduced and temporal stability has been improved to eliminate shimmering on fine textures. All RTX users can access these enhancements which particularly impact performance for 20 and 30 series users who lack FP8 support from their older architectures.
Players have reported that frame generation produces unwanted blur and flicker effects which disrupt their ability to see mini maps and health bars on user interfaces. NVIDIA created DLSS 4.5 to handle this challenge by developing an AI model which they named Preset B. The model maintains static UI elements through its game engine data buffers which permit separate management of UI and 3D content. The system ensures that text and HUD icons stay sharp when 6X frame generation runs.
Compiling Shaders progress bar has been resolved through the introduction of the new beta feature called Auto Shader Compilation. The system operates in background mode to rebuild DirectX 12 shaders after a driver update during PC operating idle times. The software improves performance by managing process execution before game initiation which results in reduced stuttering and faster initial load times. Users can enable this globally within the Graphics tab of the NVIDIA app settings.
How to Enable DLSS 4 5 Features
Open the NVIDIA app and go to About in Settings to access the new updates. The update process requires you to select the beta and experimental features checkbox. The Graphics tab will reveal new DLSS Override options after you complete the update process. RTX 50 series architecture users exclusively access 6X mode while RTX 40 series users can use Super Resolution enhancements and UI Preset B.
