Quick math on blitting pixels: - lets assume 1920x1080: 2073600 pixels.

- 4 bytes a pixel = 2073600 * 4 = 8294400 = 8.2 MB / frame.

- 8.2 MB frame * 60 fps = 480 MB/sec = 3.2 gbps = an order of magnitude higher than even your average techie's internet entire pipe. That's for 1080p. The market baseline for resolution, 4K, 4x's that. 240 fps (market baseline for gamers) adds another 4x. ~50 gbps

As long as you're willing to accept intellectually that _sometimes_ there will be video-like content played, where more than 10% of the pixels change in a frame, you now _need_ to assume some form of compression algorithm is applied on every frame, i.e. do video encoding.
