Nvidia DLSS 5 Launches on RTX 5090 Laptops with Severe Performance Hits

Key points

• DLSS 5 neural rendering causes a significant frame rate drop; in NBA 2K27 at 1440p, average FPS fell from 149.6 to 56.8 when enabled without frame generation.
• Multi-frame generation can offset the performance loss; enabling 6x frame generation in the same test pushed average FPS to 217.4, a 282.5% gain over the base DLSS 5 performance.
• Nvidia confirmed DLSS 5 will officially support RTX 40-series GPUs later in 2026, following initial optimization for the RTX 50-series.
• Gamers will only have a simple on/off toggle for DLSS 5; granular artistic controls like model selection and intensity sliders are reserved for developers.
• NBA 2K27 is the first title to support DLSS 5, available on GeForce NOW for Ultimate members streaming from RTX 5080-powered cloud rigs.

Background

DLSS 5 was revealed unexpectedly, breaking the historical pattern of major DLSS updates aligning with new GPU generations. Prior to its official launch, community tests and leaks indicated severe performance drops and power delivery bottlenecks on RTX 5090 cards. For instance, earlier benchmarks showed DLSS 5 causing 37-49% frame rate drops in titles like S.T.A.L.K.E.R. 2 and Hogwarts Legacy, with power draw increasing by up to 50%. The official launch on September 3, 2026, aimed to address these concerns with optimized drivers and developer-tuned implementations.

How outlets are covering it

Notebookcheck emphasized the severe performance penalty of DLSS 5 neural rendering but highlighted that multi-frame generation can effectively restore and even exceed baseline frame rates. The outlet noted that the current implementation lacks granular user controls, offering only a hotkey toggle. Nvidia, via The Verge, confirmed that DLSS 5 will expand to RTX 40-series GPUs later in 2026 but reiterated that users will only have a simple on/off toggle, with granular controls reserved for developers. Nvidia also highlighted the visual fidelity improvements in NBA 2K27, describing the technology as delivering 'lifelike lighting and material detail.'

Why it matters

DLSS 5 represents a significant shift in Nvidia's approach to AI-driven graphics, prioritizing visual fidelity over raw performance. The technology's severe performance penalty and limited user controls may impact adoption, especially among gamers who prioritize frame rates. However, the expansion to older GPUs and the integration with GeForce NOW could broaden its accessibility. The performance trade-offs and power delivery bottlenecks highlighted in earlier tests suggest that DLSS 5 may require significant hardware upgrades or power delivery improvements to be viable for high-end gaming.

What to watch

Nvidia plans to optimize DLSS 5 performance for RTX 50-series GPUs in the coming weeks, followed by official support for RTX 40-series GPUs later in 2026. More games are expected to adopt DLSS 5, with developers tuning the technology for their specific titles. The expansion to older GPUs and the integration with GeForce NOW could make DLSS 5 more accessible to a broader audience, but the performance trade-offs and limited user controls may limit its adoption among high-end gamers.
