Lanczos vs Bicubic
Lanczos and Bicubic are both rescaling algorithms. They can both upscale or downscale stream images. For example, you can play a game at 1440p and stream it at 1080p. Conversely, you could upscale a 720p game to 1080p while streaming. While images rescaled by either Lanczos or Bicubic look virtually identical at a cursory glance, there are differences in image sharpness and computing cost.
