As for GOG installations it is in the subfolder “ObjectsInSpace”, for me in:
G:\Objects in Space\ObjectsInSpace
Whoever locked the topic original topic at Config File Locations : Locked too early!
Other information: Game works well in UHD (3840x2160)
It works well in 8K (7680x4320) so far too.
As for now it refuses my tricks to run at 12k or 16k ;).
Feature request: Enable Anti-Alias in polygons and textures. Using the NVidia control panel to force both (for Textures set Antialias transpacency option) as 4xSSA.
The game still has its blocky charm, but you don’t have to suffer the extra “stairs” from your monitor, just those from the retro charm ;). Mich nicer for my eyes.
