So I recently got a Predator XB271HU I have it set at 144Hz with G-sync enabled. I've been playing some newer games like BF4/DOOM (2016) and within the game settings I have v-sync turn off like I'm suppose too right ? In these game I never go over 100fps and it looks dam good. So I start playing a older game called Defense Grid: The Awakening so this game is running like 800-1000 fps and the video card is like coil whining plus I don't want to run that many frames it's just not good. Anyway I was surprised I thought with 144Hz plus G-sqnc it was going to cap itself at 144Hz. So what do I do now when I play older games, what are my options ?
