2D Games graphic problem (Linear + XBR = On)

[Combone]

@Henrik

Possible fix this?



.....

I have problem in...

- Street Fighter Alpha 3 Max
- Metal Slug XX
- BlazBlue
- The King Of Fighters: The Orochi Saga
- Spectral Vs. Generation

Games with this issue will only look right with 1x rendering resolution, so try setting that. Also, texture scaling can sometimes help hide the problem.

About rendering resolution...

Test 1x + XBR + Linear..



Game looks very smoothing.

....

Test 2x + XBR + Linear..



Smoothing decreases but...Have graphic problem

Try to use hibrid instead of xbr and send a print

Test Res 2x + Linear + Hybrid-Bicubic...

When game is fully 2D you don't gain anything by increasing rendering res. Better just change screen scaling filter to nearest and you'll get rid of the blurry resize while still keeping the filter for textures and whatever texture scaling you might like.

I make simple config for 2D Games..

Res 2x + XBR OFF + PostProcessing Shader: AA-Shader + Nearest/Auto...



....

But..XBR On + Linear activated game look better.

Dunno about your definition of "better":P. IMHO clear graphics is far better than having glitches all over the place.

Anyway if texture scaling does not hide such issue completely(usually a minimum which does that is x3+) then you are stuck with x1 res or glitches, choice is yours.
Probably best way to improve 1x res further in such fully 2D games would be by some full screen upscaling shader, but there might be something wrong with those, or at least I couldn't write one which gives expected result in ppsspp and gave up on them;3.

Better = Hi-Res/HD (No Glitches)

Good idea improve 1x Res

So, i am using the latest android version and i have those annoying vertical lines in Street Fighter Alpha 3. I tried many different settings combinations with no luck. Guilty Gear works without glitches though.

I'm on Samsung Galaxy S2.

If you get vertical lines then check your texture filtering and set it to nearest.

Linear filtering on some 2d games (and even some hud elements: like text boxes in valkyria chronicles 3) will get vertical or small horizontal line garbage if used on any resolution above 1x. Nearest won't have the same smoothing effect but the lines will also not exist either.

@el_rika in latest ppsspp versions you can actually use fullscreen post process upscaling which might help games like this look better. Just select 5xBR as post processing shader and you should get high output resolution, without any extra glitches.

That shader should give similar effect to xBRZ texture scaling at high res while being more performance friendly, the downside is that it cannot give full effect on stretched graphics, which a lot of ports of old arcade games and indie games with so called "pixel art" tend to have. Looking at this game changing texture filtering from auto to nearest as suggested above will actually make that downside worse giving more blocky results on characters and backgrounds which are certainly stretched, althrough at the same time will look sharper, so just check all the glitch free options you have and pick whatever you preffer.

[el_rika]

thanks for the replies.

well, nothing works. the lines are still there and the more i change the settings the worse it gets, to the point the characters become a mess (some squares appearing and dissapearing).

now, this whole issue seems to be a little random. It is always there, but sometimes it's worse and sometimes (especially after i beat the first fighter) it's less noticeable. So, after i go into another map/stage, it sometimes becomes better without any emu settings change.

i guess there are bigger mysteries in the universe

If you didn't tried this yet - restore default settings(there's an option for that in system settings), then make sure rendering resolution is set to x1(defaults for that depend on screen resolution, so you might need to change it;p) and run the game without using savestates ~ just to make double sure your problem isn't caused by some hacks, unsafe settings or memory corruption.

If it still happens ~ it's either some new emulation bug or a problem specific to your device.
In that case - you could search if we have an issue for such problem here and if not, open one yourself(and arm yourself in patience). Just make sure to check what gpu your smartphone has - that would be rather important info and unfortunately "Samsung Galaxy S2" doesn't tell it since this model had few versions with completely different hardware.

[el_rika]

thank you very much.

I will do all that ^_^
