At high sharpness values without grain reduction 2D objects looked a bit noisy, particularly 2D map textures in the UI. The 3D world still looked great, where that “noise” resolved to my brain as detail. Anyway I ended up dropping it to 60% sharpness for that reason.
Here’s an example of what I mean. This is a 2D map, so you know the added “detail” isn’t really there, and it just doesn’t look right with the full sharpness filter. 3D objects look slightly worse at 60% sharpness, but I feel like this is a better compromise.
I would still use 100% sharpness and 0% grain reduction on games without 2D textured UI elements.
I see what you mean depending on the game though that might look okay. In that pic it makes it look like it was printed on cloth or textured paper so not entirely out of place looking. But the middle is the best of both.
What game is that by the way, the map really reminds me of Sacred 2 but that’s not from that game.
Since it’s a 2D texture, you know the 0% version is correct, and the others have added noise that doesn’t really exist. That applies to 3D too but I like it there.
