NVIDIA’s Neural Texture Compression Cuts VRAM Use From 6.5 GB to 970 MB

NVIDIA has released more details about its Neural Texture Compression (NTC) technology, which significantly reduces GPU VRAM usage by up to seven times. In a technology demo presented during one of the GTC 2026 sessions, NVIDIA revealed that its Neural Texture Compression can reduce VRAM usage from 6.5 GB to just 970 MB in certain scenes. This was demonstrated in a video comparing a Tuscan Villa and its interior. With virtually no difference in texture appearance, Neural Texture Compression represents a major advancement in maintaining graphics fidelity while freeing up GPU memory for more game content. For instance, in both the exterior of the Tuscan Villa and the interior demo showcasing detailed tableware, NTC technology provides users with high-quality textures while maintaining excellent material quality.

NTC technology is an AI-driven texture output that allows games to feature high-quality complex materials without a performance penalty. Games can benefit from the substantial VRAM reduction that NTC offers while maintaining the same texture quality. Traditionally, games use block-compressed formats like BCn, such as BC5, BC6, or BC7, which are commonly applied in 4×4 pixel formats and rendered by the GPU. However, NVIDIA has trained small neural networks that can produce the desired pixel format and texture appearance at a fraction of the size of traditional texture compression formats. Instead of using gigabytes of VRAM for textures, NTC drastically reduces VRAM…
