NVIDIA DLSS 5 Performance Cost and RTX Support Explained

Update — 13 October 2026

NVIDIA has announced a faster DLSS 5 Neural Rendering model arriving on 16 October, with half the GPU overhead of the September version. The revised model has 24% fewer parameters, approximately 118 million in total, and uses 20% less VRAM at 4K, according to NVIDIA. The company says visual fidelity remains comparable. NVIDIA also puts the cumulative Neural Rendering model speed-up since its March demonstration at 10×.

NBA 2K27 will receive the revised model on 16 October for GeForce RTX 50 Series GPUs, RTX Spark laptops and GeForce NOW. NVIDIA reports frame rates up to 1.4× those achieved with the previous model, equivalent to an increase of up to 40%. Hogwarts Legacy is scheduled to add DLSS 5 on 5 November, with Where Winds Meet following in late November. RTX Remix will receive both the updated Neural Rendering model and the new Frame Generation Performance Mode on 23 October.

For Hogwarts Legacy, NVIDIA says Avalanche Software has adjusted the DLSS 5 integration to preserve the game’s artistic style. The Verge observes that NVIDIA’s new comparison images show less aggressive changes to character faces than the March demonstration.

GTR analysis: Halving the Neural Rendering stage’s GPU overhead does not double a game’s complete frame rate. The 62–71% frame-rate losses measured in September came from the earlier model, so they do not establish the performance cost of the October version. Independent testing is still needed.

NVIDIA has also introduced a separate Frame Generation Performance Mode, called Preset C, through its app beta. Available to RTX 40 and RTX 50 Series GPUs, the mode replaces part of the optical-flow processing with a lighter algorithm. NVIDIA reports up to 35% faster Frame Generation on an RTX 5060, with minor image-quality trade-offs. Preset C is separate from Neural Rendering and does not add official DLSS 5 Neural Rendering support to RTX 40 hardware.

Update — 2 October 2026

The unofficial DLSS-NR-on-AMD project has received two more public optimization releases, with the largest new claim targeting Radeon RX 7000 GPUs. Alpha 0.4.3, released on 28 September, reported a 20% performance improvement over 0.4.2 in Reference mode and 18% in Fast mode. Developer Daniel Blanco also reported 75 FPS on an RX 9070 XT in Cyberpunk 2077 at 1080p using Fast mode.

Alpha 0.5.0 followed on 29 September with a much larger RDNA3 result: the developer reports up to a 207% performance improvement over 0.4.3 on RX 7000 GPUs. The same release lists a 5% improvement for RX 9000 and says the Neural Rendering output is richer and more detailed, particularly around skin and faces.

The 207% figure should be read narrowly: it is an up to result reported by the project for RDNA3 against version 0.4.3, not an independent GameTechReport benchmark or a universal gain across games and settings. The project remains an unofficial community implementation and is not official DLSS 5 support from AMD or NVIDIA.

Update — 28 September 2026

The unofficial DLSS 5 Neural Rendering project for AMD GPUs is improving quickly after early builds struggled with a heavy performance cost. Developer Daniel Blanco says Alpha 0.4.0 was 42% faster than 0.3.3. Alpha 0.4.1 followed with another 8% improvement, while its new priority-queue mode produced a separate 9% gain under heavier gameplay loads.

Alpha 0.4.2, released on 27 September, adds a new Fast mode for Radeon RX 9000 GPUs. Blanco reports a further 15% performance improvement over 0.4.1 at 1080p in that mode. A Reference option keeps NVIDIA’s original arithmetic, while RX 7000 cards continue to use Reference mode. The release also brings the temporal history filter and one part of the neural network closer to NVIDIA’s implementation.

These figures come from the project’s own release testing and use different version baselines or test conditions, so they should not be combined into a single cumulative performance figure. They are also not independent GameTechReport benchmarks. DLSS-NR-on-AMD remains an unofficial community project rather than official support from AMD or NVIDIA.

Update — 26 September 2026

A QuasarZone test adds power and connector-temperature measurements to the performance cost already documented for DLSS 5. In a 20-minute Cyberpunk 2077 test at 4K using an unofficial modded DLSS 5 implementation, average RTX 5090 Founders Edition GPU power rose from 509.2 W to 575.1 W.

Correction — 26 September 2026: The original version of this update incorrectly presented 582.7 W and 646.7 W as the DLSS 5 off/on PCAT readings. Those are the DLSS 5-on average and peak values. The corrected average and peak comparisons are shown below.

QuasarZone’s PCAT measurements showed average power through the RTX 5090’s 16-pin input rising from 516.5 W without DLSS 5 to 582.7 W with it enabled. Peak input power rose from 571.7 W to 646.7 W. Thermal imaging measured the hotter side of the connector at 80.9°C without DLSS 5 and 91.7°C with it enabled, while GPU core peak temperature moved from 82.3°C to 86.3°C.

GTR analysis: These measurements do not show that DLSS 5 causes connector failures. They describe one controlled workload using a modded Cyberpunk 2077 implementation, not NBA 2K27’s official integration, and should not be generalized to every RTX 5090 system. They do show a measurable increase in power draw and connector temperature in this test.

Test data: QuasarZone. GTR calculations: HWiNFO average GPU power +12.9% (509.2 W → 575.1 W); 16-pin average input power +12.8% (516.5 W → 582.7 W); 16-pin peak input power +13.1% (571.7 W → 646.7 W); connector temperature +10.8°C (80.9°C → 91.7°C). Analysis: GameTechReport.

Update — 5 September 2026

DLSS 5 is now live in NBA 2K27. NVIDIA released GeForce Game Ready Driver 616.64 WHQL for the launch, with its current documentation listing local 3D-Guided Neural Rendering support for GeForce RTX 50 Series desktop and laptop GPUs. GeForce NOW Ultimate also exposes the feature through NVIDIA’s RTX 5080-powered cloud hardware.

Independent launch measurements put the rendering cost above the pre-launch 50–60% estimate in several tested configurations. An RTX 5080 drops from 185 FPS to 53 FPS at 4K, which works out to a 71.4% reduction. At 1440p, the RTX 5070 Ti loses about 62%, while the RTX 5060 Ti 16GB falls from 165 FPS to 50 FPS with DLSS Quality — a 69.7% reduction.

The important detail is how those numbers were produced. The benchmark comparisons exclude 6X Multi Frame Generation, so generated frames are not inflating the displayed result. That makes the on/off delta a cleaner view of the rendering overhead introduced by DLSS 5 itself than headline output-FPS figures after generated frames are added. The exact cost still varies by GPU, resolution and settings, so the 71.4% result should not be treated as a universal DLSS 5 penalty.

NVIDIA will make DLSS 5 available on September 3 at 9 p.m. PT, with NBA 2K27 becoming the first game to ship its 3D-Guided Neural Rendering technology. The feature will initially be available on GeForce RTX 50 Series desktop and laptop GPUs, while GeForce NOW Ultimate subscribers will also be able to use it through NVIDIA’s cloud hardware.

NBA 2K27 is the first shipping game where DLSS 5’s visual gains and performance cost can be judged outside NVIDIA’s earlier technology demos. NVIDIA is advertising very high frame rates when Neural Rendering is combined with Super Resolution and Multi Frame Generation, but the neural rendering stage itself currently carries a substantial performance cost.

DLSS 5 extends the rendering pipeline beyond upscaling

DLSS 5 is not simply a replacement for DLSS Super Resolution. Its defining feature is 3D-Guided Neural Rendering, which operates late in the rendering pipeline using information already generated by the game engine, including geometry, motion, materials and lighting.

The model can then add or refine visual effects that are difficult to reproduce conventionally in real time. NVIDIA highlights more natural subsurface scattering through skin, better light transmission through hair and foliage, richer material response, ambient occlusion and stronger contact shadows.

NVIDIA says the system is designed to remain temporally stable and gives developers control over how strongly the neural model affects a scene. Developers can adjust structure and tone and can use masks to restrict the effect to particular objects, materials or areas instead of allowing the model to alter the entire frame indiscriminately.

NBA 2K27 is the first official DLSS 5 game

Visual Concepts is using DLSS 5 to improve lighting and material response across player models and courtside characters. NVIDIA’s examples highlight skin subsurface scattering, facial hair, jersey materials and contact shadows while preserving facial geometry scanned from real-world athletes.

The feature remains optional. NVIDIA says RTX 50 owners will need its September 3 Game Ready driver before enabling DLSS Neural Rendering from NBA 2K27’s video settings. The effect can also be toggled during gameplay and replays, allowing players to compare the neural pass directly with the conventional render.

By comparison, Gears of War: E-Day is using DLSS 4.5 alongside ray tracing, frame generation and Reflex. DLSS 5 adds a different layer, generating lighting and material detail from the rendered scene data.

NVIDIA’s headline FPS figures rely on 6x Multi Frame Generation

PC Gamer reports that NVIDIA developers estimated the current Neural Rendering implementation reduces rendering performance by roughly 50–60%. That figure refers to the cost of the neural rendering work itself, not the final displayed frame rate after frame generation.

NVIDIA’s NBA 2K27 performance charts do not isolate that neural-rendering cost. The company’s highest figures combine Neural Rendering with DLSS Super Resolution and 6x Multi Frame Generation. NVIDIA lists up to 370 FPS at 4K on an RTX 5090 and 233 FPS on an RTX 5080 under those settings.

Those charts show final displayed frame rates with the full DLSS stack; they do not isolate the performance cost of Neural Rendering. Multi Frame Generation inserts additional displayed frames after the underlying game has been rendered. PC Gamer notes that one NVIDIA example showing 258 FPS on an RTX 5060 at 1080p corresponds to an underlying rate of roughly 43 FPS before 6x frame generation expands the output.

NVIDIA says performance has nevertheless improved sharply since the technology’s March demonstration. The earlier version required two RTX 5090 GPUs, while the September implementation runs locally on a single supported RTX 50 card. NVIDIA describes that as about a fivefold improvement and says further model and pipeline optimizations are planned.

Official DLSS 5 support starts with RTX 50 Series and GeForce NOW

Official local support at launch is limited to GeForce RTX 50 Series desktop and laptop GPUs, while GeForce NOW Ultimate subscribers will also receive DLSS 5 through NVIDIA’s cloud service. NVIDIA says its specialized real-time model uses RTX 50 Series Tensor Cores to process complex lighting and materials locally on a single GPU. The company has not announced official RTX 40 or RTX 30 support for the September 3 launch.

In NBA 2K27, RTX 50 owners will be able to toggle Neural Rendering during gameplay and replays, making it possible to compare the visual changes directly against the lower underlying rendering performance reported from NVIDIA’s briefings.
