It's really well-optimized on PC.
The game unlocked at midnight, so I only had a chance to check out the settings, run a benchmark test, and try out team deathmatch for one match. The game defaulted to 2560x1080 with everything on Ultra, except for an ambient occlusion setting (was on high) IIRC, and ran at a rock-solid 60 FPS on my PC with a GTX 1070. The benchmark showed some impressive stuff going on in the background of one level, but apart from that...it's Gears. TDM was like playing the game on a 360 again, lol.
Was pleasantly-surprised to see that this game supports ultra-widescreen, too.
