PPSSPP texture scaling and auto frame skipping

[[Unknown]]

Auto texture scaling matches render resolution, so yes, 3x in that case.

Texture filtering is a feature of the PSP GPU - games specify, per texture, whether they want filtering or not. "Auto" just means, "trust the game." Linear forces linear for ALL textures, which can sometimes make some things look blurry or etc. - it's less of an issue with higher render resolutions, though. "Linear on FMV" is basically "Auto", but when a video is playing, it forces the video to be filtered.

Here's a good visual example of linear filtering:
