💡 Why Not DLSS?

DLSS is NVIDIA’s proprietary technology and cannot be directly integrated into an open-source Fabric mod in the same way as an openly licensed solution.

Oleaf instead uses AMD FidelityFX FSR 1, which is open source and MIT licensed. FSR 1 is a spatial upscaling technique that can be used across different GPU vendors, including:

• AMD
• NVIDIA
• Intel Arc
• Intel integrated graphics
