The game is using Directx 9 if the NVidia card is fine , this points to an issue as mentioned earlier as being the AMD video drivers or the Card itself.
Why first step is always a clean install of the video drivers, this relates to @ojibemukwa as well , best utility is DDU to remove all trace of the video drivers.
After a clean install of video drivers and it persists, and swapping the video card out whilst another AMD card would of been best , given the Nvidia card is fine strongly suggests a card issue.
Trialing a previous version of video drivers is also worthwhile.
