Just played Civ 6 with DirectX 12 and this game won't even start saying DX12 isn't supported.

"DirectX 12 is not supported on your system. Ensure you have the latest Windows updates and video card drivers."

Windows (Version 22H2 / Build 19045.3324) and Video card driver fully updated.

Ran dxdiag in terminal to verify I have DX12:
Processor: AMD FX(tm)-8350 Eight-Core Processor (8 CPUs), ~4.0GHz
Memory: 16384MB RAM
Available OS Memory: 16356MB RAM
Page File: 9888MB used, 13124MB available
Card name: AMD Radeon (TM) R9 380 Series
DirectX Version: DirectX 12

Tons of other people are having the same issue. 75+ people wrote here in discussions, so the actual number is probably at least 30-100x that:

Guessing there aren't game developers that track these issues on discussions here.. Refund looks like my only option.

You do realise DX12 isn't just one version, there are support levels for feature sets etc. that aren't available if you don't update.

As the game uses Nanite you need at least Windows 10 version 1909.1350 or newer, with support for DirectX 12 Agility SDK along with a Maxwell/GCN or higher GPU.

Edit: Maxwell or Polaris GPU required as game requires SM6.6

I am literally fully updated as per the post.. if your comment doesn't help, then maybe go troll somewhere else?

Your post did not have details until you edited it.

Regardless heres the info you need:

DirectX 12 (with Shader Model 6.6 atomics), or Vulkan (VK_KHR_shader_atomic_int64)
https://docs.unrealengine.com/5.0/en-US/hardware-and-software-specifications-for-unreal-engine/

R9 380 has Shader Model 6.5:

You don't meet minimum requirements to play the game.

Edit: I will say that it's not any user error, the devs don't specify this type of stuff and it's not easy for people to find out as a general "DX12" doesn't cover all this. The RX 590 and RX480 supports SM6.7 and can run this game. On nvidia's side Maxwell 9xx series cards can also run SM6.7

@Shibe Thank you! I was under the assumption that you thought I wasn't updated. "if you don't update"
Pretty junk way to do business, there should be a tool to specifically check which GPU's work for each game, if corporate profit margins didn't run the world..

It's not straightforward and the devs really should have put that in the min requirements, at best you could look at min reqs and the highest support it has but it's not an exact method.

One point about the SM6.6 requirements for both nanite and virtual shadow maps, they can be disabled and the game can still run. To do this you'll need the graphics settings mod from Nexusmods to disable nanite and virtual shadow maps can be disabled through in-game settings.

Whether this will allow you to launch and play the game is a different matter, if it has internal checks or anything else dependent on that requirement then it won't launch. Best bet is asking the mod creators to see if it's possible.

There was mention somewhere (I can't find the news article) about the devs needing to rework textures in order to not have nanite enabled. It does break some things if you disable it using the mod, crashes in Maelific/Beautific gallery locations and some puzzles may rely on hints in textures that do not load.
