Nvidia has rolled out DLSS 4.5 Super Resolution through its app, bringing enhanced image quality to over 400 games across all RTX GPUs. The update features a second-generation transformer model that improves lighting and reduces ghosting, but requires 5x more power. RTX 20 and 30 series users may experience up to 20% performance loss compared to DLSS 4.

Nvidia Launches DLSS 4.5 Super Resolution Across All RTX GPUs

Nvidia has officially released DLSS 4.5 Super Resolution to all users of the NVIDIA App, following its announcement at CES 2026. The update, which had been available in beta since last week, extends support to over 400 games and apps across the entire RTX GPU lineup, from 2018 models through the latest RTX 50 series

. Users can access the update through automatic app updates or manual installation via the company's standard software channel. This marks another step in Nvidia's ongoing push to integrate AI upscaling technology deeper into PC gaming, making advanced image reconstruction available to a broader base of graphics cards owners.

Enhanced Image Quality Through Improved Transformer Model

At the core of DLSS 4.5 lies a second-generation transformer model that delivers enhanced image quality through more sophisticated image reconstruction quality processes. The improved transformer model focuses on converting lower-resolution renders into higher-resolution outputs while preserving detail and maintaining stable motion across frames

. Nvidia claims the updated model can take advantage of additional processing headroom when available, applying more compute power to refine how it reconstructs textures, edges, and fine detail during motion. The visual improvements include improved lighting and textures, better edge handling, and enhanced motion clarity

. These refinements specifically target common AI upscaling issues, working to reduce artifacts like ghosting and shimmer that have plagued earlier versions.

Performance Trade-offs for Older RTX Hardware

While DLSS 4.5 brings image quality improvements, it comes with significant performance considerations, particularly for older hardware. Nvidia acknowledges that the second-generation Super Resolution requires 5x more power compared to the previous generation model

. This increased power draw translates into noticeable performance loss for RTX 30 series and RTX 20 series GPUs, with reports indicating frame rate drops of up to 20% compared to DLSS 4. The performance hit stems from older Tensor cores lacking FP8/FP4 support—the AI floating-point capabilities built into newer RTX 40 and 50 series cards

. While RTX 50 series graphics cards handle the increased computational demands without significant power draw concerns, owners of older hardware may need to weigh the visual benefits against potential frame rates losses. Nvidia suggests users experiencing performance issues can stick with the DLSS 4.0 "Model K" by selecting the override option in the NVIDIA App.

Stronger Scene Context and Artifact Reduction

The technical improvements in DLSS 4.5 extend beyond raw processing power. Nvidia emphasizes stronger scene context interpretation as a key advancement, with the model better understanding temporal data, motion information, and heuristics to determine what should remain stable between frames

. This enhanced interpretation helps reduce artifacts that become visible during fast camera pans, particle-heavy effects, or around thin high-contrast edges. The system now delivers cleaner edge handling and reduced ghosting—the faint trails that appear behind moving objects in motion-heavy scenes. Demonstrations at CES showed the improvements in action, with observers noting that the difference between native TAA rendering and DLSS 4.5 set to quality mode in games like Arc Raiders was barely perceptible

. These subtle but meaningful visual gains become more apparent once pointed out, particularly regarding temporal stability and the reduction of flickering and image trails.

What This Means for PC Gaming's AI Future

The rollout of DLSS 4.5 reflects Nvidia's strategic positioning as an AI company that happens to make gaming GPUs, rather than the reverse. The technology now competes in a landscape where Sony's PSSR and AMD's FSR offer alternative upscaling solutions

3

. For players with aging hardware, DLSS 4.5 offers potential to achieve playable frame rates across Steam libraries, though the "fake frames" debate continues among enthusiasts who question AI-generated imagery paired with natively rendered content. The update arrives as Frame Generation support reaches 240 games and apps, though the announced 6x DLSS Multi-Frame Generation remains unavailable in this release. It remains unclear whether Nvidia plans to improve DLSS 4.5's efficiency with older GPUs, leaving RTX 20 and 30 series owners to decide whether the enhanced image quality justifies the performance trade-off.
