Hi All,
I used a 1440p Gsync Monitor.
I’ve got two issues currently. One of which is that I’m capped at a hard 120 fps with Vsync is off. Also when I try to set the resolution reverts back.

Anyone else experienced this issue? Tried searching online with no luck.
Thanks

Yes, having the exact same issue.

And it’s now 4 days after launch. What the hell??

Micro stuttering on my end. Resolution sticks I THINK but man this stuttering is horrendous. I’m about to give up on Reach. The game is unplayable. Who the hell decided this way okay to launch now?
