Nvidia's DLSS 5 neural rendering officially launched in NBA 2K27 for RTX 50-series GPUs, but modders have already enabled it on older RTX 20-series, RTX 30-series, and even AMD RDNA 4 cards. The community has also revived dual-GPU setups reminiscent of SLI to offset the technology's significant performance impact, which can reduce frame rates by 36-38%.

DLSS 5 Officially Launches with Steep Performance Costs

Nvidia officially launched DLSS 5 neural rendering inside NBA 2K27, marking the debut of its latest AI-driven graphics enhancement technology

5

. Initially limited to RTX 50-series GPUs, the technology promises photorealism by combining training data with engine data to infer lighting and shadows

5

. However, the compute cost is substantial. Even on an RTX 5090, enabling DLSS 5 with 6x multi-frame generation reduces actual performance to approximately 61 FPS at 4K—a four-fold decrease compared to native rendering

5

. The technology interpolates five fake frames for every real frame while upscaling from 1080p to 4K.

Modders Enable DLSS 5 Across Multiple GPU Generations

The modding community has rapidly expanded DLSS 5 accessibility beyond Nvidia's official support. The DLSS Unlocked mod now enables DLSS 5 on RTX 20-series, RTX 30-series, and RTX 40-series cards through NexusMods

4

. This tool combines neural rendering with multi-frame generation via AMD's FSR 3.1 system to offset the significant performance impact

4

. The mod only supports DirectX 12 games with native DLSS upscaling and frame generation capabilities.

Developer Marcelo Guibout created an innovative dual-GPU solution reminiscent of SLI configurations, running Cyberpunk 2077 on one RTX 5060 Ti while offloading DLSS 5 processing to a second card

1

. Both GPUs connect via PCIe x16 ports operating at PCIe 5 x8 speeds, with one GPU rendering the game while the second applies neural rendering enhancements

1

. The setup runs smoothly without noticeable delay between rendered frames and DLSS 5 implementation.

AMD GPUs Join DLSS 5 Through Community Innovation

Developer danielblnc achieved DLSS 5 functionality on AMD's RDNA 4 GPUs through the closed-source "DLSS-NR-on-AMD" project

2

. The mod works with DirectX 12 games supporting FSR by using a dynamic wrapper to intercept NGX API calls and convert Tensor calculations into math compatible with AMD's matrix accelerators via the HIP RT backend

2

. Initial performance on the RX 9070 XT reached 28 FPS at 1080p in Cyberpunk 2077, improving to 30 FPS after patches

2

. The developer aims to achieve RTX 5070 Ti-level performance, which appears feasible given both GPUs' similar raster capabilities.

Real-World Performance Impact on RTX 40-Series Hardware

Testing DLSS 5 using rakanki911's DLSS 5 Swapper on an RTX 4070 Ti Super revealed substantial performance penalties across multiple titles

3

. In Grand Theft Auto V Enhanced at 1440p with maximum graphics and ray tracing enabled, average FPS dropped by 36-38% depending on the neural rendering model selected

3

. The 1% lows experienced a 31-36% reduction, with baseline performance at 96 FPS average falling to 59-61 FPS with DLSS 5 active

3

.

Hogwarts Legacy showed slightly better optimization, with average FPS declining by 28-35% and baseline 81 FPS dropping to 53-58 FPS depending on the model

3

. Visual improvements included richer colors without oversaturation, enhanced depth in stonework and fine geometry, and more lifelike character models. Early RTX 30-series mods encountered frame rates in single digits even at 720p and 1080p resolution, with massive power consumption spikes highlighting the technology's inefficiency without dedicated hardware accelerators

Nvidia Promises Official RTX 40-Series Support

Following community modding efforts, Nvidia confirmed plans to bring DLSS 5 to RTX 40-series GPUs officially

5

. Ben Berraondo, Nvidia's head of PR, stated: "Once RTX 50 Series performance is more fully tuned, we plan to work on expanding official support to the GeForce RTX 40 Series"

5

. The company initially limited DLSS 5 to RTX 50-series to avoid negative PR from poor performance on older hardware, but modders demonstrating compatibility across RTX 20-series and even AMD cards forced reconsideration.

RTX 40-series implementation will likely support up to 2x multi-frame generation rather than the 6x available on RTX 50-series

5

. Users should exercise caution with mods in multiplayer titles, as file modifications can trigger anti-cheat detection and result in bans

4

. The DLSS-NR-on-AMD mod explicitly doesn't work with games requiring anti-cheat systems

2

.

What This Means for Real-Time Rendering's Future

Nvidia worked closely with developer Visual Concepts to implement DLSS 5 as an aid rather than foundation for NBA 2K27, using scanned 3D models as base geometry before applying AI upscaling

5

. This engine-level implementation allows developers to fine-tune results according to creative intent rather than applying a global AI filter. As more games implement the technology and the dataset matures, DLSS 5 may evolve beyond current criticisms regarding artistic integrity and visual consistency

5

.

The dual-GPU approach, while impressive, represents a temporary solution rather than permanent strategy

1

. A dedicated AI card would prove more efficient than running a second general-purpose GPU, especially considering graphics card prices and DLSS 5-driven power consumption. Optimization improvements for RTX 50-series will inadvertently benefit community mods on older hardware as well, making current performance the slowest DLSS 5 will ever be on these platforms
