UI is upscaled beyond 16:9, it's atrocious. Running 21:9 here and it's bad, but that muli-monitor shot looks absolutely unplayable.
FoV doesn't feel right. Maxed at 100 yet it feels like it's 60. I thought it was Vert- scaling because it looked cropped vertically, but it's Hor+. Doesn't make any sense. Editing the config and changing it to 140 makes it look like it's actually around 100.
Vsync doesn't affect performance, people don't know what they're talking about. The Vsync method is double buffering, they need to switch it to triple to stop the halving of framerate when it can't meet your refresh rate. If you can't force triple buffering yourself (drivers, D3DOverrider), then sure, disable Vsync and deal with awful tearing. Edit: Interesting, the config file has a "Gsync" option in it, and it's defaulted to on. Disabling to see what it does..
No SLI support, and forcing SLI doesn't work. Just causes terrible flickering in menu and much worse performance ingame. NVIDIA and/or devs have to work on this. I can't be bothered to spend hours testing bits when I barely have just over an hour left to test the actual gameplay (refund grace period); isn't my job.
Edit: The game is rendering at a far lower resolution internally than what's set in the options. This is why the graphics look atrociously blurry. People report DSR giving framerate boosts and potentially better graphics. That only works properly in 16:9, as downsampling in a resolution with a broken UI results in it looking pixelated ontop of being stretched (or squished). However, if you do downsample, be prepared for pretty abysmal framerates:
