Very bad performance in Windows virtual machine
In a Windows virtual machine, the performance of Vivaldi 64 bits is very bad.
I'm a developer and due to the fact of the job I have to run Windows 8.1 in a virtual box with Parallel Desktop 12. I have iMac Mid 2011 with 2.5 GHz Intel Core i5 and 16GB of RAM. For the Windows virtual machine I dedicated to it the whole 4 core of the CPU and 10GB of RAM. Although the consumption of CPU and RAM are below 50%, Vivaldi still cannot operate properly (need very long time to scroll page, to switch tab, to open Preferences window...). With Chrome and Firefox (all are latest version), I don't have that performance issue.

have you tried chromium on windows? what did tools>task manager say when browser was slowing down?
The UI is completely rendered by JS and React and may be slower than Chrom* or Firefox.
But on most VMs the missing/faulty OpenGL or DirectX/Direct3D implementation is the problem slowing down Vivaldi.
Starting Vivaldi with commandline parameter
--disable-gpuin Desktop's Vivaldi shortcut may help.
@Gwen-Dragon awesome!! Thanks very much!
As is use many VM for Linux, i know about this.
