Confused about Anisotropic Filtering

[bslenul]

Hey!

Could be a dumb question, but does anyone can see any difference with the anisotropic filtering set to "Off" and "16x"? Because I can't :x

Here it's set to "Off": https://i.imgur.com/VgS9GhJ.png
Here to "16x": https://i.imgur.com/gfIqU8l.png
(PPSSPP restarted between each screenshot, to make sure the change was applied)

I can't spot any difference, shouldn't it look like this when AF is OFF (quick mockup, just to give a rough idea)?: https://i.imgur.com/dgbKATc.png

Note that I'm asking more for curiosity than anything else, I'd probably stick with 16x anyway, but I just don't understand :/
I thought maybe it was my settings from the Nvidia Control Panel forcing it or something, but AF was set to "Application-controlled", I even tried forcing it to "Off" globally but no matter what it doesn't seem to change anything...

In this post it's clearly working: https://forums.ppsspp.org/showthread.php...#pid123817 but it's from 2016.

So anyway, does it work for some of you? If so, any idea what I am missing? This is on PC btw,Windows 10 / i5-4670K / GTX 970, same results with the RetroArch core.

I believe Anisotropic filtering only works if rendering resolution is set above 1X which will put it into hardware render mode. Try it and see...

My screenshots were made at 4x (or 5x, I don't remember), still can't see any difference :p

sorry,

I’m not sure if this helps, but if you’ve been saving in-game PPSSPP keeps an insular save, just like a real psp.
