In addition to moving DLSS 4 with beta, NVIDIA also optimized the apply of VRAM in the latest version of DLSS SDK. Initially discovered by VideoCardzDLSS 310.3.0 improves the apply of the VRAM transformer model by 20%.
The updated trace of DLSS memory brings its overall memory impact to the older CNN model. Earlier, the DLSS transformer model used almost twice as much of memory than the CNN model, which is replacing. Despite this, thanks to the latest VRAM NVIDIA optimization, the transformer model now uses only 40% more memory than the CNN model.
At 1080p, the aged transformer model used 106.9 MB VRAM; The fresh one consumes only 85.77 MB. For comparison, the CNN model consumes 60.83 MB VRAM. DLSS memory consumption increases or decreases linearly based on resolution; The higher the resolution, the more VRAM DLSS requires. For example, starting DLSS at 4K increases the trail of the transformer model by 3.5x, consuming 307.37 MB VRAM.

Despite the advantages, you probably won’t notice the improvement of VRAM in real applications. The reduction of memory capacity for DLSS by 20% translates only into a reduction of 80 MB at 4K (not to mention 1440p or 1080p). 80 MB (or less) is almost irrelevant compared to the capacity of current graphics cards. The only exception may be the 8K resolution, in which the DLSS transformer model uses gigabyte memory (even with fresh VRAM NVIDIA optimization).
Regardless, the 20% reduction in the trace of memory is impressive, taking into account the capabilities of the DLSS transformer model. If the story repeats, we can expect that the DLL DLSS 4 file will be cut in the future. Nvidia made the same technique with DLSS 3.8.10. The DLSS 4 transformer model can boast of twice as many parameters as its predecessor based on CNN, enabling high -quality native image quality.
VRAM NVIDIA improvements relate to the strict model of an exaggerated transformer, not the production of frames. DLSS 4 was fired with a significant improvement in the generation of frames, reducing VRAM consumption by 30%. RAM generation consumes much more VRAM than a part of DLS. For example, Nvidia claimed in one of her posts on the blog Warhammer 40,000: Darktide Uses 400 MB less VRAM with 4K generation with DLSS 4 frames compared to generating DLSS 3 frames.
