The PC version of FC 26 is unplayable

Hello, The game has a bug where it automatically resets the settings to ultra every time the game is started. I had the same problems too. First, set the settings you play well with in the eafc 26 menu, either from the nvidia app or directly from the fcsetup.ini file. Then, try setting the configuration files (fcsetup.ini, fcsetup_default.ini, overrideAutodetect.lua) to read-only first, and then deny them write access for each user. That's how I solved it. However, I think the biggest problems or the settings that should be lowered are the rendering scale (even lowering the normal resolution to 720p, 1080p caused a drop in fps with the rendering scale at 100), Ambient Occlusion to medium-low, and setting Hair Strands to off. I hope this helps you solve the problem.
