Looking at your photo you posted, it looks like you have the graphics cranked WAY too high for what you are playing on. Unfortunately, with your current setup, you probably are looking at low to low medium ability to have setup in the graphics department. Also it looks like you are using the Dell branded drivers which are not the most recent Radeon Drivers which could equally be causing this, as the driver you are using is from January 2015. Ultimately Guardian, your system is going to have a rough time running this game at any acceptable framerates, but you could probably run it at low settings.
ALWAYS remember to update your drivers. Always. That is all.
