inside red rectangles is nvidia denoiser, outside is corona denoiser. Both amount 1.0.
1min. rendering, 3pass, GI/AA 4, LSM 1.0, MSI 4.0, adaptivity off, UHD cache
In this example nvidia is better(texture sharpness, env., curtain rod), except reflective surfaces and some parts of tiny geometry like kitchen doors, which are better in corona denoiser. So definitely interesting :)
