Ppsspp: Remove some texture upscaling methods?

[hrydgard]

I plan to eventually move automatic texture upscaling to the GPU.

I'm wondering if we really need all the options we currently have:

• xBRZ
• Hybrid
• Bicubic
• Hybrid+Bicubic

plus the Deposterize setting.

Bicubic will be turned into a texture filtering mode and moved directly into the shaders (it can be done in four lookups, and some hardware actually has direct support for it), but there's still Hybrid and Deposterize. I bet few people have any idea what any of these do. Are Hybrid and Deposterize really worth keeping?

Glad to see Bicubic be turned into a texture filtering mode.
Deposterize does help reduce flickers in some case.

[hrydgard]

Really? In what cases does it reduce flickering?

[Narugakuruga]

Monster Hunter Portable 3rd HD, the "CAPCOM" Logo. Though when texture scaling is off Deposterize is on, the flickering also occurs. But I turn on texture scaling and Deposterize, the flicker just gone. If only turn on texture scaling, the flickering still occurs.

[hrydgard]

When texture scaling is off, Deposterize doens't do anything - it's just a minor modifier to the output of the texture scaler. But if that's the only flicker that's fixed, that's not very strong argument for keeping it, heh.

Seems from other discussion that at least most of the modes have some purpose, I'm closing this.

[Narugakuruga]

But sir will bicubic move to textures filtering? Because it's definitely better than linear.

[hrydgard]

yes I will, later.
