mikekoz1: I just bought this game on GOG and I also have an ultrawide 3144x1440 monitor. The game does not detect my graphic card but strangely enough, Fallout 3 does! I am actually surprised updates are still being made by Bethesda for this game. It is about 9 years old!
It doesn't seem to know about any modern GPUs, which makes sense since the last time it was updated before this supposed next-gen update was years ago. I have a 1440p 16:9 monitor an an AMD RX6750 XT and it just said it couldn't detect my GPU and set things to low settings by default. I didn't have any problem running it in ultra, though. It was doing some weird division of my freesync monitor's 165hz refresh rate that resulted in bad framerates and laggy feeling controls. Configuring the AMD driver to just lock the game to 60fps took care of that. I didn't go higher because of the tendency of this game to go haywire at high framerates.
