1.4 freeze one second

[LunaMoo]

In the distant future texture scaling might be done via per-texture shader, currently through it's processed on the cpu so can't say if you can use it based on gpu and that feature can ocassionally get extremely heavy even for top end hardware to begin with, so I would still recommend trying to disable it completely.

HDD size doesn't say anything about it, so again - try to cache full iso into ram using option in the ppsspp's system settings in case that was the problem.

I can't reproduce any freezes in MHFU on my system, I'm not using 1.4 through, so try updating to latest ppsspp version. If you're using OGL backend, you should also try different one like D3d11, since newer amd gpu's might still have buggy OGL drivers with unknown side effects.

The only other thing I can think of which could cause freezes would be dumping textures(especially combined with texture scaling), but that's off by default, you can make sure in settings->tools->dev tools, near the bottom of that screen if you have "Save new textures" activated, just disable it. Standard hdd's are definitely too slow to dump large amounts of textures without problems.


Edit: BTW if by chance your mention of "antialiasing" wasn't about some forced driver AA, but about PPSSPP - which doesn't have such setting and AA is done at best via downscaling shaders combined with high render res - you probably confused it with "anisotropic filtering":P, in which case just leave that to 16x, texture filtering is very light on pc's and that particular method does improve quality of distance textures under some angles by quite a lot.
