People with modern Radeon hardware / software have been having issues with stuttering and poor performance for a while now (read years). Game client slowing down when you open Black Lion is normal. Though 'flickering Windows taskbar' does not sound like anything I have ran into. Are you running the game in 'Full screen' mode or' Windowed full screen'? I found some success in defeating stuttering issues with my Radeon hardware by separately installing Microsoft DirectX 9 libraries into windows 10 and forcing the game to run with DX9 instead of Windows 10 default. (DX12 I think). More details in other thread: https://en-forum.guildwars2.com/topic/60175-low-fps-with-5700xt/?do=findComment&comment=1401902

Bit of a necro... I too have been suffering from severe performance issues with Radeon RX5700 XT. I have been using d912pxy to make the game somewhat playable, but not really happy with that solution. Inspired by some other forums and Youtube-videos I tried running the game with DX9 libraries and what a difference. Everything runs silky smooth, no sign of the stuttering and poor refresh rate. So steps I took: 1. Download and install DX9 standalone from Microsoft. NOTE! You still need to run the installer after you extract files from the downloaded package. (do not trust random download sources) http://www.microsoft.com/en-us/download/confirmation.aspx?id=8109 2. Add "-force-d3d9" to the game launcher target. So it should be something like ("...\Guild Wars 2\Gw2-64.exe" -force-d3d9) 3. Remember to uninstall d912pxy or similar if you have it installed (OPTIONAL): * Run this program as Administrator * Disable fullscreen optimizations I have not done any extensive testing but so far things look very promising.

I have had some success making the game work with Radeon cards / drivers by installing DX9 libraries to windows 10 and forcing the game run with DX9 instead of Windows 10 default. More details in this thread: Low FPS with 5700xt - Page 2 - Account & Technical Support - Guild Wars 2 Forums
