DX11 vs DX12

[Tony Pond]

As its UE4 I though I'd try and force WRC to use DX11 via the launch options Properties in Steam:

-force -dx11

This enables DX11 for me, which seems to give me a few more % fps and less stutter, this maybe different for you of course + I'm on Linux so have to run it though DXVK (DX11 to Vulkan, which also works on Windows) or VKD3D for DX12 with Proton.

Don't forget that shaders in UE4 get dynamically compiled the first time though a stage so when comparing it may take several runs of each to get a fair comparison.

Also don't forget the **Engine.ini** and **GameUserSettings.ini** can have custom setting, which might help (docs like https://framedsc.com/GeneralGuides/ue4guide.htm ) but back up those files first!.

Hope that helps.

They have the EGO engine that is very good but decided to use crap Unreal Engine. What was the reasoning behind this?

[Tony Pond]

Chances are the Ego Editor/Design Tool is stuck as a 32bit application, which will have a 2GB memory limit and would be too costly to port to 64bit especially when compared to a massive number of already trained gfx artists and coders on UE4 that don't need 3-6 month of training to get used to the Codemaster in-house tools.

The "trained" coders and gfx artists are not as well versed in UE4 then, because this game blows.

I will try later -notexturestreaming
I suspect some stutters are due to loading. Pretty common to have traversal stutters in UE4 and sadly 5. WRC had them too.

There are a few commands which loads all textures into vram so only use it if you have loads of it. No sure if the start command will work, there is also one for the engine.ini
