After trying the drivers I was expecting more after the positive reviews. When activating it (no vsync in game) the game gets like double fps but it actually feels less smooth at 3440x1440 resolution, and it also feels like it has more ghosting and worse image quality.
I hope they improve this, frame gen from Nvidia felt much better and actually felt more smooth but I guess this will eventually improve. At the current state I wouldn't use it.
I know this is only Intel, but I have a 5950X (released same year as 10900K) and honestly I don't plan to upgrade anytime soon, at least 3-4 years. Next cpu will be Intel most likely. I hope they have something good up their sleeves.
