Tokiden

What area of the game / PPSSPP

My texture filtering is set to automatic, linear filtering, and automatic best quality; when the rendering resolution is set to 4x, there are boxes and thin lines, which also appear in other games but not as frequently.

What should happen

It should not appear boxes and thin lines appear, just as when using nearest.

You can only properly fix those problems by running affected game at X1 resolution or using texture replacement with high res textures changed to match game's math at selected res.

It can also be hidden by forcing nearest texture filtering or using xbr texture scaling, but sometimes those just look bad.

PSP games were not designed for high res nor tested with it and are full of such issues and it's not an emulation issue.

Does high-res texture replacement really help in this case? This kind of issue usually happened when tiling a part of texture that's on the edge of the atlas isn't? where linear scaling blends the color with the black color outside of the atlas (depends on how the texture clamping/wrapping mode, it can also be a repetition of the edge pixels or something)

Reference


Edit: i guess using hi-res texture can help in reducing the dark lines, since the affected pixels are smaller than the original texture that gets enlarged (causing the darkened part being enlarged too)

Try the "Smart 2D texture filtering" option, it doesn't work in all games but can clean up some of these issues.

尝试“智能2D纹理过滤”选项，它并不适用于所有游戏，但可以解决其中的一些问题。

I try it,but only has a little change, until I use tex4xbrz,black lines are disappear,but the words look weird,can I find other texture filtering to improve this situation?
