I do have a g-sync monitor. I dont understand why it caps though. I got this computer like 2 months back and i was getting around 500-1000fps on every game i was playing. Now i am just getting the 144.G-Sync?
If you're outright capped at 144Hz (ie can't get any higher, even turning down settings), then you either have an adaptive sync technology enabled, or the title in question is capped to 144Hz
