NVIDIA's DLSS 5 Debuts in NBA 2K27 with Subtle Visual Gains but Severe Power and Performance Costs

Key points

• NBA 2K27 is the first official title to support DLSS 5, which adds subtle detail to player models and lighting but is not a transformative visual upgrade.
• Testing on an RTX 5090 at 4K showed frame rates dropping from 240fps to 150fps when DLSS 5 was enabled, representing a significant performance penalty.
• Power consumption for the RTX 5090 jumped from approximately 400 watts to 525 watts with DLSS 5 active, with some users reporting power draw exceeding 600 watts and resulting in melted power cables.
• DLSS 5 is currently restricted to RTX 50-series GPUs and GeForce NOW cloud streaming, though NVIDIA has announced future support for RTX 4000-series hardware.
• Modders have developed workarounds to enable DLSS 5 on older GPUs or split rendering workloads across multiple cards, though these are unofficial and carry risks.

Background

NVIDIA introduced DLSS 5 in March 2026 as a neural rendering technology, but initial demos sparked backlash over 'AI slop' artifacts. The official launch in September 2026 with NBA 2K27 aimed to address these concerns with a more restrained implementation. Prior coverage indicated that while the technology promised lifelike graphics, it carried a steep performance hit of 50-60% and was initially limited to the latest RTX 50-series hardware.

How outlets are covering it

Engadget emphasizes the poor cost-to-benefit ratio, noting that the subtle visual gains do not justify the massive power increase and frame rate loss, which risks hardware damage. NVIDIA's official blog highlights the technology's potential for 'lifelike lighting and material detail' and its availability across various devices via GeForce NOW, focusing on the positive collaboration with 2K Games. TechPowerUp and Tom's Hardware focus on the community's response, detailing how modders are using multi-GPU setups and hybrid tools to mitigate performance issues or enable the feature on older hardware, suggesting a fragmented and controversial adoption landscape.

Why it matters

The launch of DLSS 5 highlights the ongoing tension between AI-driven graphics enhancements and hardware limitations. The severe power and performance penalties raise concerns about the sustainability and practicality of such technologies for mainstream gamers, while the limited initial support and reliance on mods indicate that the technology is still in a developmental and controversial phase.

What to watch

NVIDIA plans to expand DLSS 5 support to RTX 4000-series GPUs in the future. Developers such as Capcom, Tencent, and Ubisoft have committed to supporting the technology in upcoming titles, but specific titles and release dates have not yet been announced. The community will likely continue to develop mods and workarounds to optimize or enable DLSS 5 on unsupported hardware.
