Vision Transformer: A Fundamental Upgrade
DLSS 4 introduces a revolutionary vision transformer architecture, replacing the previous convolutional neural network. This represents the most substantial enhancement to DLSS super resolution since the introduction of DLSS 2 in 2020. The new system significantly reduces common visual artifacts such as smearing, ghosting, and shimmering, while also delivering improved ray reconstruction capabilities. Importantly, this feature will be available across all RTX graphics cards through Nvidia's app, allowing users to enhance older games without waiting for developer updates.

Multi-Frame Rendering: The Next Generation
Exclusive to the upcoming RTX 50 series GPUs, multi-frame rendering technology takes frame generation to new heights. Digital Foundry's testing reveals that this feature can triple or quadruple a game's perceived framerate by injecting two or three additional AI-generated frames. The performance impact is notably efficient - while the initial frame generation adds about 10 milliseconds of latency, subsequent frames incur diminishing penalties: approximately 4ms for the second frame and 2ms for the third, resulting in a substantial 71% framerate increase.

Performance Considerations and Hardware Requirements
While the vision transformer technology will be accessible to all RTX cards, questions remain about the performance requirements and VRAM impact, particularly for multi-frame rendering. The upcoming benchmarks will be crucial in determining how well RTX 20 and 30 series GPUs can handle DLSS 4's demands. Of particular interest is the RTX 5070's ability to implement multi-frame rendering with its 12GB memory configuration, which could validate Nvidia CEO Jensen Huang's claims about it matching the RTX 4090's performance.
Competitive Landscape and Future Implications
The timing of DLSS 4's reveal coincides with significant developments in the upscaling space, including updates to third-party solutions like Lossless Scaling. This competitive environment continues to drive innovation in frame generation and upscaling technologies, ultimately benefiting end users with improved gaming experiences and performance options.
