NVIDIA has confirmed an update to its DLSS frame generation technology for RTX 40 series graphics cards. This improvement aims to reduce video memory (VRAM) consumption while increasing overall performance, leveraging a dynamic model. optimized artificial intelligence.
Evolution of DLSS technology
Introduced with DLSS 3.0, frame generation technology was designed to fill gaps between rendered frames, providing a smoother gaming experience. Since its launch, NVIDIA has continually improved this technology, increasing upscaling quality and performance. The latest update, planned for RTX 40 GPUs, introduces a new AI model, similar to that of RTX 50 cards, although the latter benefit from additional features like multi-frame generation.
Jacob Freeman, an NVIDIA spokesperson, said that this update would reduce latency and reduce VRAM consumption, freeing up resources for other aspects of games, such as textures or mods. For example, in one case, the new DLSS version saved 400 MB of VRAM while slightly increasing frames per second (fps). While the improvement may seem small, it could be significant for users of GPUs with 8GB of VRAM, which are often limited in modern games.
New features with DLSS 4.0
The DLSS 4.0 update brings several notable advancements, including:
- Improved frame generation : Available for RTX 40 and RTX 50 GPUs.
- Ray Improved Reconstruction : for more precise management of ray tracing effects.
- Super Resolution and DLAA (Deep Learning Anti-Aliasing): DLAA is currently in beta phase and compatible with all RTX GPU series, from 20 to 50.
However, multi-frame generation remains exclusive to RTX 50 cards. For RTX 40 users, these updates nevertheless represent a notable improvement in the gaming experience.
Impact on latency
One of the challenges of generating DLSS frames is increased input latency, due to the time required to predict and render additional frames.
NVIDIA claims that DLSS 4.0 reduces this latency, although benchmarking shows similar results between DLSS versions 2.0, 3.5, and 4.0. NVIDIA Reflex technology, included in DLSS 3.5 and 4.0, plays a key role in latency management, delivering performance comparable to DLSS 2.0.
Only “part” of DLSS 4 will be available
This update to DLSS frame generation for RTX 40 GPUs demonstrates NVIDIA's commitment to optimizing performance and resource efficiency, even for earlier generations of GPUs. Although it does not introduce all the innovations reserved for RTX 50 GPUs, it offers significant benefits for users, especially those with resource-constrained graphics cards. For demanding gamers, these improvements represent an opportunity to fully exploit the capabilities of their hardware while anticipating the demands of future games.
