Issue is as stated above. Responsible commit is github.com/hrydgard/ppsspp@4567acaf92 by @DanyalZia merged into master with v0.9.1-2045-ga3f2fcf github.com/hrydgard/ppsspp@a3f2fcfd8f by @hrydgard

Setting texture filtering to Linear or Linear on FMV doesn't work anymore for Tekken 6 since then, both ingame and during FMVs:

(click on the screenshots to observe the issue clearly)

FMV (pixellated even after Linear Filtering is forced in the graphics menu):

Ingame menu (letters remain pixellated even when Linear Filtering is forced in the Graphics menu):

Last working revision is v0.9.1-2043-g99d4ef1 github.com/hrydgard/ppsspp@99d4ef1e06

FMV (smoothed out as expected):

Ingame menu (letters are smoothed out as expected with Linear Filtering)

I suspect other games may be affected by this commit too. Will add them into the issue report if and when I find them.

Tested on the following machine:

Soul Calibur is also affected by this issue it seems.

Why would the game use alpha testing for video? Well, it might be "enabled" but not really doing anything. I guess we could try harder to detect those cases.

Or just give up and let filtering break things at 2x.... which ain't great.

That would probably be the same reason as always - alpha testing and color testing are free on the PSP so games sometimes just leave them on by accident, probably just forgetting to disable the state, as there's no harm anyway if you draw things that don't match the test criterion.

But yeah there are more checks we can do to rule out effects of these, and use the result of those checks for the linear filter enabling...

Broke the filtering in MGS PW or broke the game? That's some ambiguous wording.

The filtering works in FMVs now, but forcing Linear Filtering still does nothing for the pixelated ingame fonts. Same thing for Soul Calibur Broken Destiny.

Does using something more like this help?

    if (g_Config.iTexFiltering == LINEARFMV && g_iNumVideos > 0 && (entry.dim & 0xF) >= 9) {
        magFilt |= 1;
        minFilt |= 1;
    }
    if (g_Config.iTexFiltering == LINEAR && !gstate.isColorTestEnabled()) {
        if (!gstate.isAlphaTestEnabled() || entry.GetAlphaStatus() == TexCacheEntry::STATUS_ALPHA_FULL || !gstate.isTextureAlphaUsed()) {
            magFilt |= 1;
            minFilt |= 1;
        }

@unknownbrackets Just adding those lines in? Or do I have to replace any prior lines with these ones?

In any case, appending those lines to the current master version of the file does not resolve the issue. Lnear Texture Filtering is still broken for the ingame fonts in Tekken 6.

Replacing the if block that starts with g_Config.iTexFiltering == LINEAR with those. But, these should apply separately anyway. That means we can't safely force linear filtering because it's inventing pixels that may have other alpha values than the game expects.

Or we could make it ignore that and people will complain about the green outlines around characters or etc. in some games again.

@unknownbrackets Unfortunately, https://github.com/hrydgard/ppsspp/issues/6088 doesn't resolve the issue in Tekken 6 for the pixelated fonts. Setting it to Linear still causes it to be pixelated.

Again, a reminder of what it used to look like with Linear Filtering set:-

Seems to be the only straggler though. Other games have functioning Linear Filtering now when forced in the options.. (like Crisis Core etc.)

@unknownbrackets commented on GitHub (Feb 10, 2019):

So, thinking about this, I guess what we could do is use sampler objects (GL3.3+ / GLES3) to bind the texture in two slots, and then do BOTH nearest and linear.

That way, we could do color and alpha testing based on the nearest value, but still output the linear value. I think that's more or less staying true to the goals of higher render resolutions.

We could take this further, and when upscaling (not not texture replacements? not sure...), we could bind the original texture to the second slot. This would again allow for using nearest which would give us better chances of color tests and alpha tests working correctly.

Yeah, that's definitely a possibility, although the mix between smooth filtering inside the solid regions coupled with the hard edges against the surroundings might look odd. Also, if the test is done against an ugly color it would still be able to bleed into the solid region.
