How to Fix: Blurring Graphics in Older Games

How to fix blurring graphics in older games such as Command and Conquer: Tiberian Sun and Worms Pinball.
I decided to make this video after encountering the above problem while playing Tiberian Sun with friends at a Lan Party (Yes, we still play the old classics!)
I was unable to fix it at the time, and after doing a bit of searching was unable to find a fix on the internet.
After a bit of playing about I discovered that the "Morphological Filtering" option in the AMD Catalyst Control Centre was the culprit. I would have discovered it sooner, however trying to set this option on an individual games profile did not appear to work, only setting it globally.
With this setting switched off, the games now run normally again, hooray!
Now if only I could figure out why Unreal Tournament '99 runs far too quickly on my old Althon64 laptop.
