I'm not sure if this got posted or not, but in the event that it did I'm posting an answer to my own question for others' benefit: I had to enable Freesync in the monitor's settings. Provided you have the same monitor, you'll find it through Menu - Picture - Game Adjust - Freesync
Now I have another issue and it appears to be related, although Freesync is indeed enabled. I was running Fraps prior to enabling Freesync and noted my FPS to never get higher than 60. I did some research and was able to enable 144Hz on my monitor and video card and then adjusted in-game settings in an MMORPG that I play to reflect 144Hz refresh rate; however Fraps still reports a max of 60 FPS.. Does Fraps have reporting issues beyond 60 FPS? That's next on my list to research. The MMORPG in question is Neverwinter. I'm not sure if perhaps the game has issues with scaling that high being that it came out in, what? 2006? Something like that; but the video/display settings in-game did indeed have a 2560x1080 resolution at a 144Hz refresh rate to choose..
