I noticed that before updating my Radeon 5700XT Drivers to 19.9.2, I had the 19.8.2 drivers and games like the original Sims, Warhammer 40k: Winter Assault, Prey (2006), and the main 4 Quakes (links below on Quake for support to fix this) were all working perfectly fine. Full and in the middle of the Screen with black bars (for anyone who has played old games while upgrading their computer, they know that this is normal).
That was with 19.8.2. Here is why I would bring up 19.9.2. I updated it to 19.9.2 and all of a sudden, the games shrunk and went into the upper left corner of the screen. I thought it was weird and I got worried. Turned out, that after using DDU (Display Driver Uninstaller) and reinstalling 19.8.2, the problem was solved.
This really isn't a question, it's more of a problem that needs to be fixed by AMD.
