@DaDarkDragon Everytime UE4 launches a new release it is an assumption it will work with the latest drivers at launch date (even for previews), so it is not guaranteed it will work flawless in other conditions, even more since this specific release has a lot of changes in the rendering module, which depends on certain things like graphics card drivers and directx version. I suggest to update the graphics card driver going to nvidia website (type nvidia drivers on google) and select your card model (RTX 2080) and Windows 10 64 bit and download the 419.67 release. Also, there is a Creator driver which should improve performance, according to NVidia, for several 3D software (not games) and UE4.22 is among them.
