User blog:One True Slash/Assassin's Creed Unity Resolution Lock

I had to recently re-install AC Unity and faced a huge problem. The resolution is locked at 1280x720. I tried editing the .xml file, and it didn't help. I tried editing the .ini file and it didn't help either. Re-installing the game again didn't help too. I looked the problem up, but all the results are about the ratio issue. I found only one person who has the same problem and nobody has replied to the guy since 2014, and the answer he got was both dissapointing and made me want to off myself for seeing such stupidity. My PC can't handle Unity on the best settings, but it used to run fine on low settings. Please, if you have any idea how to fix this stupid problem, tell me.
