Hi Angela,
Make sure that your 2020 Design is running using the Nvidia as the default graphics processor (it’s a setting in the Nvidia control panel).
The image was the 2K fast one – this forum doesn’t allow larger attachments. The 4K (3K in size, 4K in resolution) one is here:

Honestly though, I don’t see why you would bother with a 4K render under most circumstances. The average inkjet or laser will do a good jub of blurring (think primitive antialiasing) the edges of lines for you.
As I mentioned, there are a few things to try when running the render but the most important is to close off as many other processes as possible including anti-virus. Also there are certain anti-virus programs that people just should not be using and these are Nortons/Symantec, Mcafee, AVG and probably a few others. Good ones are Bitdefender, Avira, Avast but I only use the built in Microsoft one with an occasional scan using Malwarebytes.
Also try and get rid of any bloatware on your system – if it isn’t necessary, uninstall it.
