FSR VS DLSS - Which has the most overhead?
Radeon's FSR 2.0 upscaler and Nvidia DLSS technology work in fundamentally different ways. FSR 2.0 is designed to be cross-platform and use generic GPU resources, while DLSS is designed to use the AI/Tensor performance of Nvidia's RTX series graphics cards. That explains the performance differences that we see below.
DLSS and FSR use the same input resolutions in the Performance, Balanced, and Quality profiles, but when FSR uses generic GPU hardware resources, DLSS uses a hardware block on Nvidia's RTX GPUs that are otherwise unused. Where AMD's FSR takes resources from other tasks, DLSS uses the untapped AI performance of Nvidia's RTX GPUs. The result is that FSR has a larger performance impact than DLSS, making DLSS faster.
While DLSS is faster, it is worth remembering that it only works on Nvidia RTX series GPUs. For non-Nvidia users, and users of older Nvidia GPUs, FSR 2.0 is the only game in town. If you can't use DLSS, it doesn't matter if it runs faster on Nvidia's RTX hardware.
