Development Getting Started & Setup

Hello Everyone! I wanted to know if I'm the only one who has such a VERY strong drop in performance in the viewport (pt on and pt off) ?? On different computers (4090/3090ti/3090/3080ti/3060) performance degradation is the SAME and very strong (2-3 times). Drivers after, license Twinmotion. Will this be fixed in future updates? Thank you very much!

Agreed, multiple machines, 3080 and 3090, all substantially slower...sticking with 2022 til they fix this.

Hello,

Our apologies for any inconveniences this issue might be causing. The team is actively investigating performance degradation issues between Twinmotion 2022.2.3 and Twinmotion 2023.1 Preview 1. We are aiming to get these issues fixed for our next 2023.1 Preview 2 update.

Best,

Raghib

I am running the Twinmotion 2023.1 preview 2 and it still gives me an average 10 FPS compared to the 40 FPS in 2022.2.3 even with the overall quality lowered in the preferences.

Same here. I can no longer run it properly on my 3050Ti in the viewport. In 2022 it was perfect, what have you guys done? :-(

Hello everyone,

​

For anyone still experiencing performance degradation between Twinmotion 2022.2.3 and 2023.1 Preview 2, please submit a bug report here and share a copy of your original 2022.2.3 Twinmotion file, and the converted 2023.1 Preview 2 file. Make sure these files are packaged with the Resource Collector (Edit menu > Resource Collector > Compress files) so all relevant data is retained when sharing. THis will allow us to determine what might be causing the continued performance degradation.

Best,

Raghib

Hi, any news on this? running 2023.1.1 and the viewport is unusable with pathtracer on in lowest settings. Thanks

Thank you very much glad to hear! You are the best! Twinmotion is growing up and it's thanks to your Team!

Preferences don't effect PT, only samples effect it.

I am still seeing performance loss in Preview 2 as well

Hi ,

There were some performance improvements delivered in the updates after this thread was created that should have improved performance in most instances. For issues you're experiencing in 2023.1.1, please submit a bug report here and be sure to include a copy of your DxDiag report and any affected files you noticed this happening on.

Best,

Raghib
