Feature request: Add an option of enable Linear mipmap filtering for tilesets/unit sprites #10845
Description
Before creating
- This is NOT a gameplay feature from Civ VI, BNW, or outside - see Roadmap
- This is NOT a gameplay feature from Vanilla Civ V or from G&K - If so, it should be a comment in Missing features from Civ V - G&K #4697
Problem Description
Currently, the tileset graphics/unit sprite graphics are all using nearest neighbor filtering.
This causes graphic distortion when the game is doing non-integer scaling, and the game is nearly always doing non-integer scaling... That really bugs me.
This is particularly noticeable in graphics that take the form of diagonal lines. As you can see in the sceenshot below, the sword of the Hakkapeliitta is distorted：
This is also somewhat noticeable in graphics that take the form of vertical lines. As you can see in the sceenshot below, the Pike of the Pikeman is distorted, the black vertical lines have different width:
Using Linear filtering for tilesets/unit sprites can fix this issue. It will also make the graphic a bit more smooth (people who don't like it may call it "blurry" though.) I understand that this might be somewhat a matter of personal taste. So I think the best solution might be adding an option in game advanced settings, to allow players choose between Linear filtering and nearest neighbor filtering.
