I tried both solutions including decreasing the visibility distance. Sadly the error is still there.
Gonna give the "Enhanced Configuration Project mod" a shot. can't find a link though. :(
It worked for me. I ran the autoconfig in the external preferences programm then set distance at slightly under 900m, terrain details at normal
, The other in-game options are all maxxed out, resolution is at 1680x1050x32 which is my monitor's native resolution. (Textures still look like 16bit despite the 32bit setting btw.), and it works
. increasing the terrain details to high
produces the out of mem error.
I would say BIS just set the maximal settings ~available~ much higher than was possible at the time the game was released without actually testing at all whether the game would run at those settings (my guess is that there was no hardware at the time that could have done it), so those "very high detail terrain " and 5K visibility settings are purely "for show".
