Why can people run 2023 TM (PT) with a GTX card if they download a patch from another user. but cannot if they dont have the patch.

I could NOT run TM 2023 with my GTX 1080 with PT on. But I downloaded a patch from another user on this site and now MY GTX 1080 has done many renders with PT on with no problems at all. Why does twinmotion wish users not render with PT on with GTX cards when it is a simple task to fix it?

You can? can you please point me to this patch?

I only say the patch works with TM 2023.1

Hello ,

Thank you for using Twinmotion and wanting Path Tracer to work with those GPU in the latest versions. Unfortunately with the new Unreal Engine 5.1 with 2023.1 Preview 2 those cards are not enabled to used Path Tracer due to performance issues that you could encounter.

We recommend you use Twinmotion 2022.2.3 for projects that need to use the Path Tracer until you can have a GPU that can work for those version. Here are the currently known issues for the current release:
