Ideas
I am not really concerned with dithering animations , I just can't look at the crosshair multiplying on my screen, it's really distracting. Without TAA enabled my crosshair multiplies like on the picture, that can't be a feature ffs... I need a clear crosshair 😭 Apex has always been a mess filled to the brim with meaningless visual clutter, but having my crosshair look like this is really distracting. I am done with Apex if that's a feature...
Suggestion - don't look at crosshair, learn to aim looking at the enemy model especially in mid and more so close range fights. Apex is no Valorant or CS where you must land headshot (and even there people don't look at crosshair as far as I know). Apex is tracking game / shot leading game and for that you actually need to look past crosshair (if I could I would actually turn it down entirely, e.g. in H-cog metal side verticals would be enough for me.
Only case where you look at crosshair is mid-far, far range shots = your G7, 3030, sniper shots where you have time to align and even intentionally hit heads = 3x+ scopes.
I agree that visual clutter in Apex is big, but as we can see from majority of casual players = they like shiny things which includes animations not only skins. So clearly that is part of the Apex, pity you can't turn it off if you prefer competitive advantage (I am sure you can, it is just not publicly advertised aka your potato graphics cfg). Just need to accept it and work around it. E.g. figure out which scope suits which gun better as actually animations differ per scope as well. For me I in many cases use much higher scope even closer range just to avoid visual clutter = it is easier for me to move mouse like crazy due to lower FOV vs not seeing what I am aiming at with say 1x scope.
