Breath Of Fire III

[LunaMoo]

I don't experience any filtering nor as a matter of fact scaling turning off within this game, however it flickers every once in a while which is pretty awful and I wouldn't consider it enjoyable to play, meaning not going to spend my free time on testing it;p.

Post process scaling should always be active, it can't "deactivate" itself, so your problems might be backend specific, I only tried d3d11, but can guess vulkan might have more issues as not only it's still somewhat new aka buggy, drivers often sucks for it and it's results might differ quite a lot between different people.



By "realtime texture scaling" I meant aliaspider:rtscale branch, I merged it to my private ppsspp version in here which currently is updated up to latest ppsspp version however my branch has a lot of different changes as well, including hacks, features and personalized defaults.

Normally texture scaling is processed by CPU, applied per texture and cached. It's reasonably fast(at least xBRZ, other methods sucks), through it can show textures gaining resolution with a delay similar to unreal engine games and it can skip scaling some textures completely as otherwise it would become extremely demanding in a lot of games.

Post process shader scaling is done by GPU, but applied to everything at once, it's also applied only to x1 res which makes 3D graphics ugly and 2D graphics in non psp native resolutions will also be inferior, but at least it's fast and works for everything even tiled textures which will become glitchy when applying any per texture filter(Street Fighter looks awful with per texture scaling for example).

Realtime texture scaling is done on GPU which should be fast as well, however it's per texture and not cached in any way, since there might be quite a lot of textures in use every frame, it makes it very heavy outside of few lighter games like for example some Harvest Moon game.
