AC not working in 3440x1440 (21:9)

[d1s1nformat1on]

Hi - Recently picked up an 34" ultrawide, 3440x1440p 21:9 ratio, 144hz monitor - everything else (ACC, F121, Dirt Rally 2.0) just kinda "worked" out of the box for it - except for AC and I can't figure it out.

In both Content Manager and AC standalone, it recognises the resolution as an option

Go to load in to drive and the Loading Screen shows up as expected:

But once the game loads, I get a weird screen that is entirely black except for the menu options:

I can access the setup menu:

And I can Click Drive and my HUD options of choice load up:

But everything else is Black...
Driving around works, I get audio and FFB - hell, if I focus on the minimap, I can cut laps, but it's far from ideal as I'm sure you could imagine.

I tried setting the resolution back down to 2560x1440 (the base 16:9 ratio for 1440p - this is the only change I made to my settings) and end up with this:

So it's clear the game is working and not trying to send it to another monitor or anything whacky, but it's just not outputting at the 21:9 aspect ratio correctly...

Anyone have any ideas on this?? I'm in no rush seeing as I'm not currently signed up for any leagues in AC at the moment, but there are some I plan to join if I can get this fixed and I have a few friends I regularly just "get on and drive" with from time to time

Thanks in advance

Sometimes I had the same problem - in my case I resolve this when I change my postprocess filter settings ingame (default: sol). I think it depends with sol/csp versions...

use Mode Tweaks: Tripple for custom resolution and then put them on 1 screen:

I have the same kind of Ultrawide curved, same resolution but 100 hz .... an never had such a problem.

Did you try to rename your Documents/ Assetto Corsa folder, launch the game ( original launcher ) which create new documents, just choose this new resolution and see if it works or not ?

If it works you'll be able to copy most saved files into the new documents, including your controllers ( without the older graphic settings of course as surely the problem was there ).
Surely the 1st thing to try.

NB Oh I forgot: check the files integrity in Steam is also worth an action.

Have you tried use "Fix resolution automaticly" in video settings but unthick Fullscreen. Then go to Controlls, and under SYSTEM tab mark "Fullscreen"?

No good in triples mode, same thing, but centred

Trying to load it with Post Processing just "off" doesn't work - I just get this weird grey/pink coloured screen - I can hear the game load in as I get car audio, but visually, no loading flash screen, no menu, no visual of the car, just a wash of a single colour.

Funilly enough, Sol filter was not the default setting for me (it was just "default") - I changed it to "SOL_" and I now have an image, but the entire skybox is black and as a result, everything else is kinda dark (but visible at least, so this is a start).

Now to figure out why the skybox is missing...

I ran a verify Integrity Check before any of these tests - not sure if it specifically helped, but it's always worth a go when you run into issues.

EDIT: [UPDATE]
I changed the version of CSP I was using and I have a skybox again

I was using CSP ver0.1.60, which is the "recommended" version apparently. Changed it to 0.1.75 (which is "untested") and it worked... weird

Not really weird.

Manual of the newest SOL clearly states that at least CSP1.69 is required.

Just a lill hint, step back one version to 1.74. CSP1.75 has a bunch of annoying bugs, 74 worked fine.

Ah - good to know - thanks
