How many of us saw a vsync option coming which would include the entire XBox family, from the OG XBox One to the Series X/S? I'm glad they did it because it does at least give other XBox users a chance to sample it to whatever degree the given console is able to support it. If they don't like what they see or feel, they have the option of going back to 30 Hz (which will yield 30 FPS in most cases).
First of all, I am floored with how well the Series X supports the 60 Hz vsync. I haven't seen it skip even one frame on the most demanding course (Quail Hollow Official), nor have I seen one screen tear. It feels absolutely golden to swing the club now, even more consistent and smoother than when I play it on my PC. I occasionally see judder on my screen on the PC, but not on the Series X, while playing 2K21.
And the putting... oh my, it's taken to a new level! I'm so much better able to gauge the putt strength now. It simply makes for a much more enjoyable experience. They killed it with this move, IMO!
On the down side, I did try it on my XBox One X, which I still have connected to my TCL Series 6 in the living room, last night. I have to say that it didn't fare quite as well as the Series X. The backswing felt pretty smooth and unrestricted, but the downswing doesn't feel quite as responsive. I was leaving everything out to the right because my downswings were slower than what I was producing on the Series X. I even spent time on the range and recalibrated my swing at 60 Hz on the One X, and I still found the swing not as easy to manage as on the Series X.
I suspect it won't hold up well on an OG XBox One, which I still have here, but I'll have to connect back up to test. I'm curious enough about it to see where it's at that I'm planning to do that. I will post my thoughts on it here once I've done so. I don't have access to an XBox One S, which reportedly had 7 to 9% more processing power than in OG XBox One. If I had one, I'd like to see if I could discern any difference between it and an OG XBox One.
I want to close out this post by saying that the simple inclusion of this one graphics option in this one game; vsync: 30Hz/60Hz, has now somehow ratified my purchase of an XBox Series X. My greatest curiosity with the Series X has always been, how is it going to change the PGA TOUR 2K21 play experience if it's able to run the game at 60 FPS. I can safely say that it has surpassed my loftiest expectations!
