Submitting a major bug report here that has been ongoing for at least 6 months and is still not fixed. Have submitted multiple dxdiags / warnings, etc - still nothing. Submitted another recently.
Water maps are simply unplayable, regardless of the computer setup. My own system has a 5800x / 3080 with 32GB ram / NVME. Others I play with have 2070s, 1000 series, various CPUs. All of us are experience the same issue anytime a water map is played.
We have however narrowed it down to happening only on water maps - specifically as soon as we or AI are building docks/boats.
My framerate starts around 130 on 3440x1440 and ends up grinding down to less than 10. Usually about 15-20 minutes into the game. This happens both with and WITHOUT mods, on official AND custom.
A few minutes after slowdown, the red message of “You may be experience low FPS - trying turning down settings, etc…” appears. Then it’s just a slow motion slideshow with game clocks not matching up after a while.
Game files verified, mods deleted, etc - all the generic stuff, drivers up to date, windows, etc… Game is broken.
Thanks
