Advanced Features (DLSS/FSR)

Both GPUs support Frame Generation, but they get there through different ecosystems. The Quadro RTX 4000 uses DLSS 3.5 + Frame Generation, while the Radeon RX 6600 relies on FSR Frame Generation + AFMF. Both can help smooth out supported games, but they are not on the same feature stack.The Quadro RTX 4000 gets NVIDIA DLSS, which still tends to look cleaner in motion. The Radeon RX 6600 leans on FSR, which is flexible and widely supported, but usually a bit rougher at the same settings.
