PPSSPP texture scaling and auto frame skipping

PPSSPP texture scaling and auto frame skipping
Hello
I have 2 questions, first - is there any advantage of setting texture scaling to auto? I have xBRZ enabled and auto looks same like 3x, also my rendering resolution is set to 3x - is auto adjusting scaling power to the same as rendering?

Second - auto frame skipping, if I set skip to 1 and enable auto, is that means my game will skip 1 frame per sec. at max, ONLY IF there are slowdowns? No disadvantages to having it OFF all the time? (and supposedly get minor slowdowns in some intense parts of games like summoning in Crisis Core...)
Some people reported back in the days it is broken due to the flickering screen, is it still persistent?

RE: PPSSPP texture scaling and auto frame skipping
I recommend keeping texture scaling off, though it's more of a personal taste, i think it looks like crap, and it's also resource intensive.

And yes, afaik auto frameskipping will only skip when there's slowdowns, i usually keep it to 3 and auto.

RE: PPSSPP texture scaling and auto frame skipping
Having texture scaling on OFF gives some 2D graphics glitches when resolution is set to higher than native, also 2D elements gets sharper and more clear with xbrz for my taste.

One more thing - in texture filtering we have nearest (looks terrible) linear, linear on FMV and auto.
Auto is giving me the same as both linear and linear on FMV, what is the difference between those options??

I keep it at Linear in FMV, which doesn't filter some things, such as the hud in Monster Hunter, just Linear will filter everything,which makes 2d graphics blurry, Nearest means no filtering.

RE: PPSSPP texture scaling and auto frame skipping
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:

RE: PPSSPP texture scaling and auto frame skipping
Okay, now everything that I asked is clear, thank you guys Smile

I have yet another question, is there any succesful method of counteracting graphical glitches while rendering res. is set to higher than native?
Lots of text boxes, 2D portraits, fonts gets messed up with some lines/ bars while going higher res.
The only way that clears almost everything of this is xBRZ / Hybrid scaling method, but xBRZ tends to make ugly graphic even worse (like sky in some games get this painted looks instead of beign just smooth)

xbrz 3x is first, scaling of second in the attached screenshots
Compare the sky and font at the lower left, letters looks definitely more clear and better, but sky gets weird... maybe some shader setting could help?
I have gaussian, bloom, colors, gamma correction set to ON, Luma shader.

RE: PPSSPP texture scaling and auto frame skipping
I think someone mentioned that changing "screen scaling filter" helped. Here's detail on what's causing the lines:

As far as the artifacts, that's because xBRZ is trying its best. In this case, texture replacement (supported in the latest git builds) could potentially help.
