On a Fellow players request, I went to settings - Video - Advanced settings - V-sync, and changedv-sync from Adaptive V-sync Half Refresh to disabled,
I could swear I had tried that before but for some reason it worked out now.
I am tabbing back and forth and the game behaves as it should, no more stuck on 30 fps with major input lag! I am in Titanfall heaven!
Consider my problem solved!
