Early DLSS 4 test showcases cleaner images and multiplied framerates

Nvidia DLSS 4 enhances image quality and boosts framerates with multi-frame rendering.

: Nvidia's DLSS 4 shows significant improvements in image quality and frame rate performance with its new multi-frame rendering. This technology, seen in early tests by Digital Foundry, introduces more AI-generated frames and minimizes upscaling glitches. Multi-frame rendering, exclusive to the upcoming RTX 50 series, can triple or quadruple perceived framerates while slightly increasing input latency. The switch from a convolutional neural network to a vision transformer is a major enhancement, but performance costs and VRAM impacts remain unclear.

Nvidia's DLSS 4, as tested by Digital Foundry, demonstrates considerable advancements in image quality and frame rate enhancements due to its novel multi-frame rendering feature. This early insight reveals how the technology injects additional AI-generated frames to multiply framerates while addressing previous upscaling errors. Multi-frame rendering is specific to the upcoming RTX 50 series GPUs, potentially tripling or quadrupling game framerates by inserting two or three extra frames. Despite successfully boosting performance, this method comes with a latency cost that is not as substantial as earlier versions of frame generation technologies.

The technology's shift from using a convolutional neural network to a vision transformer accounts for the most significant improvements since DLSS 2 in 2020. This transition has notably reduced artifacts such as smearing and ghosting, while ray reconstruction has also been enhanced. DLSS 4's new vision transformer feature will support all RTX graphics cards, allowing players to update older games independently of developer patches. However, it still raises questions about its overall performance cost on different GPU models, particularly those from the RTX 20 and 30 series.

While the potential performance costs and VRAM impact of multi-frame rendering remain to be disclosed, the technology's ability to work with just 12 GB of memory on the RTX 5070 tests Nvidia's claims. The performance capabilities of this feature in comparison to flagship models like the 4090 represent a significant topic for future benchmarks. Additionally, the Nvidia app's capability to assist users in updating games may further solidify DLSS 4 as a pivotal advancement in AI-powered game rendering, pending real-world performance validation.
