DIFFERENCE BETWEEN DIRECTX VERSIONS

[Adolf Rozenberg]

hello what is DIFFERENCE BETWEEN DIRECTX VERSIONS from the launcher MENU?

"- DX 11/12 selection when launching the game

We recently included support for DirectX 12 and since then we have had some issues where players had to start the game forcing a specific version of DirectX. To make it easier to do this for everyone, we introduced a popup when you launch the game with the latest hotfix (Update 34, Hotfix 5). It gives you three options

Play Deep Rock Galactic: Uses the last chosen setting. If you haven’t chosen a specific version of DirectX before then it defaults to DirectX 12. This is also the mode the game is launched in via the desktop shortcut.

Play Deep Rock Galactic (DirectX 12): Starts the game using DirectX 12

Play Deep Rock Galactic (DirectX 11): Starts the game using DirectX 11

The first option might seem superfluous, but we added it for two reasons:
To make subsequent startups easier by letting you just click ‘play’ if you already selected the version of DirectX you want to use
You don’t get this popup when using a desktop shortcut, it uses the first option by default. So you can set the game to start with your preferred version of DirectX by launching it through steam once and then keep using a desktop shortcut after that. "

From the QA in the discord.

Short answer is that Direct X 12 allows the GPU to receive instruction from multiple CPUs.

that's but one of the many major improvements DX12 brought to the table. better to just say "it has better performance but is not compatible with all hardware setups"

That is a wrong answer. DX11 still supports multi thread. Ergo multiple CPUs via the OSs scheduler.




What is correct is DX12 has less overhead allowing for more draw calls. By allowing more draw calls you can fully load the GPU more consistently without being bottle-necked by the CPU.

Everything drawn in game is a draw call, and some items can be many draw calls. For example every particle effect is generally a draw call. And Deep Rock has allot of them.

Not really, you're just being pedantic.

Eh, fair comment.

Which version runs better thou?
If properly optimized dx12 is superior, but this isn't the case for many games.

on experimental dx12 runs very well but on either it has some hitching. I have been using it for a while with no real issues on mainline release.
