Using an eGPU and Wacom Cintiq on the same TB Controller

Hi there,

 

 I am looking to get a Razer Core X to throw my RTX 3090 into it to add some grunt to my Blender renders while traveling to and from work with my Dell Precision 7730. The only question I have is if using both an eGPU and a Wacom Cintiq Pro 16 (which connects video and input thru Thunderbolt) would cause any issues? During my research I have consistently read that using 2 eGPUs on windows 10 with one TB controller is nigh-impossible. Does this same limitation apply when plugging in a drawing tablet into the second Thunderbolt port?

 

 Much obliged.

According to the following specs, Wacom Cintiq connects via a USB-A port.

This would not cause any problems with the eGPU if hosted off the Precision 7730 USB-A port.

Only issue of stuttering would be if it was hosted off a TB3 eGPU enclosure's USB-A port for enclosures with I/O ports using a single TB3 controller.  TB3 enclosure using dual-TB3 controllers (Razer Core X Chroma, Mantiz Saturn Pro, as per Buyer Guide) do not exhibit this issue.

 That is the Cintiq 16

 

 I have the Pro 16

 Looking at the specs it appears to use USB-C DisplayPort Alt Mode (instead of thunderbolt which I naturally assumed). Does this change anything?
