Set the game to borderless windowed and use the two .ini files to manually put your 21:9 resolution. There should be a guide somewhere about it on the internet, you're not the first one asking 😉
Btw. my PC bit the dust while I was exploring Far Harbor... there must have been a shortcircuit on the motherboard or in the PSU... cause it smelled like something got burnt and the fuse blows each time I try to power the PC :awe:
Goodbye my trusty Q9450 and GTX670 🙁 You servered well over the years... especially the CPU! Such fond memories throughout the years.... I'm now waiting for Broadwell-E next week and GTX1070 and I'll start building from scratch 🙂
Sorry to hear the news 🙁
Though BW-E and a 1070 will chew through this game. I just installed my GTX 970 and difference is drastic compared to the 7970. FO4 loves some NVIDIA cards.
