Is there a software conflict with UE4 slowing Adobe InDesign?

I’m writing documentation at work for UE4, when ever I open a UE4 scene it starts lagging out Adobe indesign to the point where I can see adobe refreshing as I scroll.

This happens with any size UE4 scene.

It might not be a specific UE4 thing but it’s the only time I’ve had issues with another app open (maya, UDK ect is fine)

Anyone have an idea of how to remove the lag or is it a known issue?

How much GPU RAM is Indesign taking up? I have that kind of lag while i use another software with UE4 open when i start to run out of GPU memory.

Thank you for the response, I’ll check that out.

Does anyone have any tips on how to check/monitor GPU RAM? I’ve never looked.

I’m running a GeForce GTX 660Ti with 2GB of RAM, I don’t think it’s the card. The system has 16Gb of RAM on top of that.
