An RTX 3080 can still deliver strong gaming performance, but an unofficial experiment with DLSS 5 shows how quickly performance can collapse on unsupported hardware. In one test, Deep Rock Galactic reportedly fell from about 138 FPS to roughly 3–5 FPS after DLSS 5 Neural Rendering was enabled.
The test used an unofficial implementation of leaked DLSS 5 software on an RTX 3080. NVIDIA currently supports DLSS 5 Neural Rendering on RTX 50-series GPUs and has announced plans to expand official support to RTX 40-series cards, while official RTX 30-series support has not been announced.
The result does not establish that the RTX 3080 cannot run advanced rendering techniques. It demonstrates the severe performance cost that can occur when experimental software is forced onto unsupported hardware.
DLSS 5 changes neural rendering
NVIDIA describes DLSS 5 as 3D-Guided Neural Rendering, which uses AI to generate more realistic lighting and materials by combining information from the game engine with trained models.
DLSS 5 is separate from DLSS 4.5’s Super Resolution and Dynamic Multi Frame Generation features. DLSS 4.5 introduced 5× and 6× Dynamic Multi Frame Generation on supported RTX 50-series GPUs.
DLSS 5 Neural Rendering is currently supported on RTX 50-series GPUs. NVIDIA has announced plans to expand official support to RTX 40-series cards after further optimization.
RTX 50 remains the current official target
NVIDIA’s current compatibility information lists DLSS 5 3D-Guided Neural Rendering for RTX 50-series GPUs. NVIDIA has also announced plans to expand official DLSS 5 support to RTX 40-series GPUs after further optimization.
DLSS 5 officially launched on September 3, 2026, with NBA 2K27 as its first supported game. RTX 30- and RTX 20-series GPUs do not currently have official DLSS 5 Neural Rendering support.
Blackwell-based RTX 50-series GPUs currently provide the hardware platform for official DLSS 5 Neural Rendering support.
What happened to the RTX 3080?
The RTX 3080 result came from an unofficial implementation of leaked DLSS 5 Neural Rendering in Deep Rock Galactic. Before the Neural Rendering workload was enabled, the card reportedly produced about 138 FPS.
After the experimental Neural Rendering path was enabled, performance reportedly fell to roughly 3–5 FPS. That represents a performance reduction of about 97%, rendering the game effectively unplayable.
Other unofficial tests have also shown severe performance problems when DLSS 5 Neural Rendering is forced onto older RTX GPUs. These results are experimental and do not represent NVIDIA-supported DLSS 5 performance.
Little-known fact: An RTX 3080 Ti news/165942-leaked-dlss-5-slows-geforce-rtx-20-and-30-cards-to-1-4-fps” data-type=”link” data-id=”https://vgtimes.com/gaming-news/165942-leaked-dlss-5-slows-geforce-rtx-20-and-30-cards-to-1-4-fps” target=”_blank” rel=”noreferrer noopener nofollow”>reportedly managed only about 7 FPS running Cyberpunk 2077 with the leaked DLSS 5 Neural Rendering path enabled.
Why Ampere struggles with Neural Rendering
NVIDIA’s official DLSS 5 support currently targets RTX 50-series GPUs, while RTX 30-series cards lack official support. Unofficial testing shows that forcing DLSS 5 Neural Rendering on an RTX 3080 can result in a severe performance penalty.
The difference reflects the hardware and software requirements of the Neural Rendering workload. NVIDIA has not announced official DLSS 5 support for RTX 30-series GPUs.
Modders have developed alternative implementations for older RTX cards, but these remain unofficial and can have significant performance and compatibility limitations.
RTX 40 cards can run unofficial DLSS 5 mods
Unofficial DLSS 5 implementations have demonstrated functionality on RTX 40-series GPUs, but they can still impose a substantial performance cost. NVIDIA has now confirmed that official DLSS 5 support is planned for RTX 40-series GPUs after further optimization.
The unofficial results should not be treated as representative of NVIDIA’s eventual official RTX 40-series implementation. NVIDIA is currently focusing on optimizing DLSS 5 performance on RTX 50-series GPUs before expanding official support.
DLSS 4.5 is the safer option
RTX 3080 owners can continue using supported DLSS features without experimenting with leaked DLSS 5 software. NVIDIA’s DLSS 4.5 Super Resolution update is available across GeForce RTX generations, though RTX 20- and 30-series cards may experience a greater performance impact due to their lack of native FP8 support.
DLSS 4.5 also introduced Dynamic Multi Frame Generation and 5× and 6× modes, but those advanced frame-generation features are designed for RTX 50-series GPUs.
For an RTX 3080, officially supported DLSS features remain the safer choice than unofficial DLSS 5 implementations.
Little-known fact: DLSS 4.5’s Ray Reconstruction half carries no performance penalty on older cards, but its Super Resolution half runs on FP8 and costs RTX 20/30-series users 20–30% of their frame rate.
Modded DLSS 5 carries extra risks
Unofficial DLSS 5 modifications are not equivalent to NVIDIA-supported releases. Community implementations can introduce performance problems, crashes, image-quality issues or compatibility problems, and their behavior can change as games and drivers are updated.
Anti-cheat compatibility can also be a concern with unofficial modifications. Community projects have demonstrated DLSS 5 on older RTX GPUs, but NVIDIA does not currently provide official DLSS 5 Neural Rendering support for RTX 20- or RTX 30-series cards.
NVIDIA has confirmed that official DLSS 5 support is planned for RTX 40-series GPUs. The company has not announced official support for RTX 30- or RTX 20-series cards.
The bigger reason for RTX 50
NVIDIA’s RTX 50-series GPUs are currently the only GPUs with official DLSS 5 3D-Guided Neural Rendering support. NVIDIA has focused on optimizing the technology for RTX 50-series hardware and plans to expand official support to RTX 40-series GPUs.
DLSS 4.5’s 6× Dynamic Multi Frame Generation can create multiple AI-generated frames between traditionally rendered frames, but this feature is separate from DLSS 5 Neural Rendering.
The RTX 3080 can run unofficial DLSS 5 implementations, but early testing has shown severe performance penalties. NVIDIA has not announced official DLSS 5 Neural Rendering support for RTX 30-series cards.
TL;DR
- Unofficial testing shows an RTX 3080 dropping from roughly 130 to 138 FPS to 1 to 4 FPS with leaked DLSS 5 Neural Rendering.
- NVIDIA officially targets DLSS 5 Neural Rendering at RTX 50-series hardware because Blackwell provides the required fifth-generation Tensor Core FP8 acceleration.
- RTX 3080 owners can continue using supported DLSS 4.5 improvements, including Ray Reconstruction and Super Resolution, without experimenting with leaked software.
- Modded DLSS 5 builds remain unsupported and can introduce performance, stability, image quality, update, and anti-cheat compatibility problems.
