As long as I was using TM 2022.2.3 I had no problem with the Direct X 12. With the last release ( 2023 preview 1) the Direct X 12 is desactivated and impossible to re-activate it .
My graphic card: NVIDIA Geforce GTX 1070.
An idea?
Thanks in advance
Hi ,
Due to stability issues, Unreal Engine 5.0.3 removed support for DirectX Raytracing on Nvidia GTX series cards. SInce Twinmotion 2023.1 moved to Unreal Engine 5, this change was inherited to the new version of Twinmotion, so GTX cards can no longer use Path Tracer in the new version.
If you need to continue to use Path Tracer, we recommend continuing to use the 2022 versions, or upgrading to an RTX series card from Nvidia, or an AMD Radeon RX 6000 series card or newer.

For real? I have the NVIDIA GeForce GTX 1080ti, will there be no more compatibility? Thank you for your feedback
Thank you for your explanation.
You should write it somewhere in your configuration files.
Kind regards
sorry.

I have The Nvidia P4000 on my laptop - worked ok with Preview 1 but with Preview 2 now get an error message regarding Direct x12 not being checked when it is!
Any update on this issue?
Hello, I have an rtx 2080 super graphics card. But twinmotion 2023. Preview 2 gives an error with directx 12, although it is enabled in the settings.
Hi,
We are currently in the process of updating our documentation to reflect these changes. The updated documentation should be available soon.

Hi ,
Similar to the NVIDIA GeForce GTX 10-series, the QUADRO P-series uses the same architecture as the 10-series and leverages software-emulated raytracing and support for these cards was removed in Unreal Engine 5.1, which is what Twinmotion 2023.1 Preview 2 utilizes.
You'll either need to upgrade to an RTX GPU or AMD equivalent for Path Tracer in the 2023 versions, or continue using the 2022 versions with your current GPU.

My company's computer，use 3060ti，after renew yesterday，still Unable to use raytracing，Direct X 12 desactivated。😂
Hello ,
We are aware of a bug where some RTX graphics cards are unable to run path tracer in the 2023.1 Preview 2 update. The developers are working on a fix for this.
If you could submit a bug report here and share a copy of your Twinmotion.log files (Where to find Twinmotion .log file), this can help the developers more quickly find a resolution for this issue.

I finally resolved this issue when I upgraded my Windows system to win10 21H2, which was previously a version of win10 1909.
I checked here : https://docs.unrealengine.com/5.1/zh-CN/hardware-and-software-specifications-for-unreal-engine/
😂
Hi,
As , and through our investigations absed on the log files we received, for anyone on an RTX card experiencing this issue, it is caused by using an older version of Windows 10. Updating to Windows 10 64-bit version 1909 revision .1350 or higher, or versions 2004 and 20H2 revision .789 or higher should resolve the issues.
For anyone still having issues after updating Windows, please submit a bug report here and share a copy of your Twinmotion.log files (Where to find Twinmotion .log file) and we can continue investigating,

Hi, we recently had the same problem,
two of our computers works with path tracing without trouble,
one had dx12 issue but solved after installed up-to-date direct X
but the other one couldn't use path tracing feature even after dx12 enabled,
all the graphics cards are rtx 4000
