Please describe your issue in as much detail as possible:
I just bought an eGPU to improve the performance of Dota2 on my iMac. The setup is a Razer Core enclosure with AMD 5700XT. I use the eGPU for internal display acceleration. (No second display)
When Dota 2 is running on Vulkan there is a significant delay in registering the mouse input on the screen. For example at the character select screen if the cursor is at the top left and you drag it down to the bottom right to click on the character potrait 'Zeus' I experienced a 3 second delay before Zeus is actually selected.
This phenomenon goes for all mouse clicks and is independent of whether you are in an actual game or not. It is also not dependent on network status as it happen from the get go at the start screen.
The effect is exaggerated with cranking up the display settings to 'best looking'
Rebooting Dota2 and running with OpenGL I do not experience this issue.
I would love to run Dota2 on Vulkan if it means improved performance on my setup and I only play Dota2.
Would really appreciate if you could look into this.
Many thanks

Steps for reproducing this issue:
Install eGPU linking to iMac via TB3. No second display.
Run Dota2 Vulkan with option 'Prefer External GPU'
Effect is exaggerated with maximum display settings.
