Nvidia DLSS 5 Expands to RTX 40 Series After Achieving 5X Performance Gains

Nvidia Confirms DLSS 5 Support for RTX 40 Series GPUs

Nvidia announced that its AI-powered graphics technology, DLSS 5, will extend beyond the GeForce RTX 50 Series to include RTX 40 Series GPUs1

. The company revealed this decision in a forum post, addressing concerns from the gaming community about artificial hardware limitations1

1

. Initially positioned as exclusive to RTX 50 Series graphics cards, DLSS 5 represents Nvidia's most computationally demanding AI model to date2

. The neural rendering technology uses 3D-Guided Neural Rendering to add photorealistic lighting and material details to PC games in real time3

Performance Optimization Shows Dramatic 5X Improvement

Since its March announcement, Nvidia achieved a 5X performance gain for DLSS 5 through aggressive model optimization1

2

. The original demonstration required dual RTX 5090 graphics cards, but within two months, the company improved the model by 50%, enabling it to run on a single RTX 50902

2

. By July, performance improved by 2.5X, and by August, the 5X improvement allowed DLSS 5 to run across all RTX 50 graphics cards2

2

. These gains resulted from a combination of hardware optimization, software kernel improvements, and co-design work that made the model smaller, faster, and more realistic2

. Despite these advances, DLSS 5 currently causes a 50% to 60% hit on frame rates, with testing on NBA 2K27 showing drops from 140fps to around 70fps even on an RTX 5090 card1

RTX 50 Series Takes Priority for Model Tuning

Nvidia's current focus centers on optimizing performance for the GeForce RTX 50 Series, with model updates expected later this fall1

. Once RTX 50 Series performance reaches full optimization, the company plans to expand official support to the GeForce RTX 40 Series1

1

. This staged approach makes sense because RTX 40 Series GPUs lack Multi-Frame Generation support, requiring the AI model to be fine-tuned before it becomes viable on Ada Lovelace architecture2

2

. The company needs to adapt DLSS 5 to work efficiently with the fourth-generation Tensor cores found in RTX 40 cards3

AI-Driven Graphics Upscaling Transforms Visual Quality

Unlike previous DLSS versions that focused on Super Resolution, Frame Generation, and Multi-Frame Generation for gaming performance, DLSS 5 takes a different approach by enhancing visual realism4

. The technology uses 3D-Guided Neural Rendering, analyzing the rendered frame along with color and motion vectors to understand scene context4

. This enables DLSS 5 to add natural light scattering through skin, light transmission through hair and foliage, tighter contact shadows, and improved global illumination3

. Nvidia designed the neural rendering system to preserve the geometry and proportions created by game artists, ensuring the AI enhances rather than alters the original artistic vision4

Current Availability and Modding Community Response

NBA 2K27 became the first game to support DLSS 5, giving gamers their initial opportunity to experience the neural rendering technology3

. The feature is available on GeForce RTX 50 Series desktop and laptop GPUs, as well as GeForce NOW Ultimate, where games stream using RTX 5080-powered cloud gaming rigs4

. Nvidia indicated that development teams are working to integrate the technology into additional games1

1

. Meanwhile, the modding community has already discovered unofficial methods to enable DLSS 5 on RTX 40 Series GPUs in select titles like Cyberpunk 2077, though users experience a 60% drop in frame rates1

1

. Given Nvidia's history with model tuning, speculation exists that RTX 30 support might eventually arrive, as GPUs down to the RTX 20 Series already support DLSS 5 through unofficial mods2

What This Means for Gamers and Future Expectations

The expansion of DLSS 5 support to RTX 40 Series represents a significant shift for gamers who invested in Ada Lovelace architecture. If Nvidia achieves its optimization goals, reducing the performance cost from 50-60% to potentially 10-15% by year's end, DLSS 5 could become practical for everyday gaming without requiring Performance mode upscaling2

2

. This matters because it would allow RTX 40 Series owners to enjoy photorealistic effects without the current severe impact on frame rates. Watch for model updates this fall that should bring faster performance to RTX 50 Series first, followed by the official rollout to RTX 40 Series. The timeline remains uncertain, but Nvidia's rapid optimization progress suggests support could arrive within months rather than years. For now, RTX 40 Series owners should monitor official announcements rather than relying on unofficial mods that compromise gaming performance significantly.
