Revit 2023 3D orbit/navigation slows down when I open Twinmotion 2023.

Hello, I`m encountering this issue with Revit 3D  orbit and navigation frame rate suddenly drops the moment I open a Twinmotion instance, no matter if its an empty scene or not in Twinmotion.

 

The behaviour is weird because its also somewhat inconsistent. Sometimes when I create a new 3D view, it will return to normal for a few minutes and then again drops down after working or switching between applications. This indicates to me that is not a hardware limitation on my side, especially since the Revit model is quite small and the TM scene as well.

 

The only thing  I could think of is maybe a RAM limitation but I dont know if that can affect 3D viewport frame rate.

 

I`m using a RTX 3070 Ti, 8gb VRAM, 16 RAM on a AMD Ryzen™ 9 6900HX and as I said, it works fine untill I just open Twinmotion. It also returns to normal the moment I close Twinmotion instance.

 

I also had a look on my Nvidia settings panel but with no effect unless there is some setting that I dont know of.

 

Is it something related to how Revit accesses CPU/GPU resources? Is there some conflict with Twinmotion? It like Revit wants the whole system by itself or something.

I should probably ask this in Twinmotion forums too but I wanted to hear from Revit side as well.

 

Did anyone encountered this?

I have not checked with older version of Twinmotion so it could be somethinn with their update but I doubt its the problem is on their side.

Meanwhile I upgraded my RAM to 32 GB, same issue, no matter how complex or simple the scene is, Twinmotion limits Revit framerate. I am sure Revit si the cause because it doesnt happend with other BIM programs.
