As far as performance goes, I have absolutely butter smooth frametimes, and 100% GPU Utilization, playing at 3440x1440 using the Digital Foundry suggested settings, except Motion Blur off and AA set to Camera Based. V-sync turned off in game, turned on in Nvidia Control Panel.
90+ FPS frequently. I got 98 FPS in the benchmark. For reference I got 79 FPS in the benchmark with Ulitmate Quality preset.
My frametimes as I said are perfect, I do get occasional hitches from moving around the world but it is not frequent, and I do not have any hitches when just standing around.
I believe two things for why I'm having a much smoother experience compared to others.
1. I am using G-sync
2. I have Hardware-Accelerated GPU Scheduling turned on. Before this setting I never got 100% GPU utilization in games, 99% at best.
Hardware Specs:
Windows 10, Version 2004 (Required for Hardware-Accelerated GPU Scheduling)
2080 TI, 1980 Mhz Core, 7500 Mhz Memory, PCIE 3 x16
6700k, 4.6 GHz all cores
16 GB DDR4 3200 CL14
Game Installed on Crucial MX500 1TB SSD
An example of how my frametimes look, I'm honestly really happy with how the game performs on my machine!
