No true ultrawide support in a 'high-end' engine?!

Title says it all, it’s about time that Epic makes this engine actually state of the art. EVERY single UE5 game has broken post-processing on ultrawide monitors. Depth Of Field effects appear incredibly shimmery and stair stepped. This is unacceptable, i have games from 2005 that properly support ultrawide monitors.

Tested games that exhibit this problem:

Silent Hill 2 Remake
Silent Hill f
Stalker 2
Still Wakes The Deep
Until Dawn Remake
ProjectTeaser

Any UE game that uses Depth Of Field appears pixelated and jaggied even on native resolutions with no upscaling involved. (DLSS quality makes it a tad bit more acceptable, but DLSS should not be necessary anyways if the engine would perform and work properly)

So far i have refunded every single UE5 title because of the broken ultrawide support and because of the abysmal stuttery performance even on my high-end rig.

You guys should really take Unity and Godot as prime examples, those engines do not exhibit shader/loading stuttering and do properly support ultrawide monitors out of the box with no broken post-processing effects.

And NO, this is not a game specific problem as i can easily recreate the broken effects on self made projects as well (upto UE 5.7)
