Are you sure you hit confirm after you did UI Optimization on 1440?
Both your screenshots do look blurry as if nothing has changed, however when I personally test this option it looks … (more)nothing like yours and does in fact scale it up very nicely.
You have to hit confirm after you check the box otherwise it won't work.
Optimization on.
Optimization off.
It does make the UI slightly bigger but this can't really be avoided. It has to do with the way it's scaling the UI.
The reason that the off version looks so blurry is because the pixel scaling ratio is farther away from 1:1, (IE: True pixels)
Looking at Phalanx Charge's Icon, here is what the base icon, scaled icon (no UI Optimization) and scaled icon (UI Optimization) look like side by side.
The reason why the UI Optimization version isn't blurry (and also slightly bigger) is that it's exactly double the size of the other icon.
Each 1x1 pixel is instead turned into a 2x2 pixel. There is zero data loss and it scales up perfectly.
Notice how four of the original icon fit into the perfectly scaled version, making it 2x2. The unoptimized version, is slightly smaller, this means that the computer has to "make up" (blur) data in order to properly scale it. Nexon could have used a better scaling method, and the game does seem to support picking your scaling method now to some degree at least. (Under the laboratory tab under options)
What you're asking for should be within grasp and as a player who would like to be able to just play in a 1:1 scaling ratio at full screen this is a nice middle ground if Nexon allows players to pick the scaling method they like best.
1:1 Scaling presents problems in widescreen of players being able to see more or less at certain resolutions so being able to pick which scaling method you want to use is a way to make sure players aren't gaining "unfair advantage" by playing in a different resolution.
Here's the skill, scaled to the same size as the unoptimized UI, but with different scaling methods applied.
Nearest Neighbor is my personal favorite.
Top Left: As it appears in game
Top Right: Nearest Neighbor
Bottom Left: Hermite
Bottom Right: Lanczos3
As for allowing players to scale their UI and keeping the relative position of the chatbox in relation to the window size, please yes Nexon. These should be easy additions and would also give us more freedom in controlling how our game looks and feels graphically. (less)
Sadly these items only drop or have higher drop rates in lower level areas from when those areas were the end game.
If Nexon wanted crafting to be easier they could include these items in … (more)the higher level areas.
They reason they probably don't do this is because on reg server where these items are tradable, it gives newer players something of value to sell to the higher level players.
In reboot however, this isn't the case so you could argue that leaving it like this makes the server "harder" (more time intensive) than reg server.
Which is probably why Nexon hasn't/won't touch it for us. (less)
