Advanced Features (DLSS/FSR)

A critical advantage for the GeForce RTX 4090 D is support for DLSS 3 Frame Gen. This allows it to generate entire frames using AI/Algorithms, essentially doubling the frame rate in CPU-bound scenarios or heavy ray-tracing titles. The L40 lacks specific hardware/driver support for this native frame generation tier.The GeForce RTX 4090 D gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The L40 relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
