Hello
Currently, in-game, SSAA is the best setting to eliminate aliasing and smooth out edges in the game.
However, this setting is extremely demanding just like the warning. enabling this setting alone can bring down up to 100 fps in gameplay. But the image quality of it is worth it in many cases. A good middle ground between this is SSAA 2x which is currently only possible by changing this line in the config file: backgroundScale:r=1.5 (4x is 2), which offer little to no difference to 4x and doesn’t took as much performance.
For example, comparison between settings
1440p SSAA off
1440p SSAA 2x
1440p SSAA 4x
As you can see in these picture (it would be more noticeable if you do it in-game and see it in-person while moving). The quality between SSAA 2x and 4x is indistinguishable, however 2x offer much more comfortable FPS for gameplay. But this config will go away if we change any setting again, or we had to set the config file to read only. So, my proposal is that since there is a graphical overhaul going on right now, adding more option to SSAA should also be one of the considerations, as of right now we can already do that with the config file, making it an in-game setting would be very appreciated.
Thank you.
