Thanks guys, all helpful advice.
Glad to know I am not the only one suffering GPU performance issues. I have forced-configured GalCiv4.exe to use the Nvidia video card. Even then, GPU performance hovers around 88%.
This is not even an FPS game.
Only time I see performance this bad is when game uses a C#-based graphics engine. (i.e. Unity ?). However, I don't see any unity libraries loaded.
Also suspect a resource-leak, as UI performance gets worse over time. I just relaunched game, and scrolling of the map is much better now than it was just before I saved last night.
65 Threads seems a bit excessive. Will keep a closer eye on this and see if this changes over time....
Not a big fan that it maintains three socket connections with ec2-xx-xx-xx.compute-1.amazonaws.com, even though I have it configured to not collect game data. hmm....
Also, perfectly content to disable the background nebula-clouds map rendering, but have yet to figure out how to do that. I am sure it adds to atmosphere, but after a bit, I am ready to turn off all of these bells-and-whistles and just focus on the game-play.
