PSA: How to set Dynamic Render Quality & Fix Resolution Problems
So a lot of people are having major performance issues with this game, and they're also talking about poor resolution scaling. It seems necessary to clarify exactly how that works in this game, because It's all rather counter-intuitive.

The internal resolution of the game is not determined by what you set in the basic video settings menu - that's only the resolution of the Ui.
The game's baseline internal resolution is actually controlled by the Dynamic Render Quality setting,
Ultra is 4k, High is 1440p, Medium is 1080p, and Low is 720p.
The game is then up- or down-scaled to whatever basic video resolution you selected.

The "Resolution scaling" option is based on percentages of these settings.
80% Resolution Scale with Medium Dynamic Render Quality will be scaling off of 100% of 1080p, not off of what you set your basic display resolution to.

If you want to play at native 1440p, or native 1080p, it's important that your Dynamic Render Quality setting match, or you'll either be rendering at 4k at 1080p, or 1080p at 4k.

DLSS and FSR2 are a nightmare in their own right and I'm not quite sure how they interact with this equation, but I see almost everyone being confused by this very unusual approach to resolution selection.

Hoping other people can contribute their own findings and we can get to the bottom of this labyrinthine settings menu.

so what if i want to play at 1440p like high and 90%?

still don't get it, if i use above 100% resolution with DLAA or DLSS it automatically turns off them, meaning i put 125% and DLAA Off, then put DLAA On again and Resolution sets to AUTO and again, dead loop...only way it works its 100% + DLAA or DLSS

i'm on a 3840x1600 screen

if Dynamic Render Quality is set to high it's rendering internally at 1440p and your resolution will be scaled to whatever 90% of 1440p is, regardless of the setting you set in "basic video"

I honestly have no idea how DLSS is implemented here because that's supposed to be controlling the internal res with quality settings. I don't understand how DLSS at 1440p Balanced translates to the internal resolution of the game when we're factoring for all of these other settings. There are like.. two separate scaling systems implemented here operating side-by-side. It's really damn weird.

Also, at least as far as I can confirm in my tests (and it seems digital foundry found this as well) there isn't any kind of dynamic resolution scaling in the game at all. The "Dynamic" part of "Dynamic Render Quality" seems to be totally missing.

Also, as for the unusual aspect ratio.. yeah, again, clueless here. I've never seen a game handle a settings menu this poorly.

i cant play always 30 fps and sometime the game run smootth at 90 fps with the same setting

This is good info, thank you.

13900kf
4090
1440p/280hz
150% res scale

With the render setting at high/1440p, not Ultra, watching HWInfo64 makes WAY more sense now. CPU useage has gone up, still not where it should be, between 30-40%, only hitting 8 p-cores, no threads. No e-cores. GPU use went up too, I can consistently pull over 400 watts from the 4090 now. The spikes on the benchmark graph are smaller in magnitude too.

I'm not seeing a difference in resolution of the game between High or Ultra Dynamic Render. I do see a difference in LOD and Ambient Occlusion though. Am i trippin here or what is going on?
