I've had this monitor for a little while and am loving the G-Sync/144hz combo, it's hard to go back to 60hz now. However...from my understanding Gsync is supposed to get rid of tearing while not adding on that noticeable input delay that is synonymous with vsync. Also(correct me if I'm wrong) the g-sync range is from 30-144hz, so as long as I'm in between there I should reap the benefits. So something I'm noticing in an FPS game(Cod 4) is when I'm at 144fps locked it looks great, but feels somewhat like a smidgen of input delay where my movement isn't as 1:1 as it should be. When I cap my fps to 125(random number) the input delay is completely gone and aiming is snappy, while losing some visual fidelity....So could someone explain this phenomenon? 144, or 125, both are in Gsync range, so why does 125 fps feel so much snappier when aiming compared to 144fps?
