Sadly there's nothing we can do expect hope Petroglyph finds another patch method. The long save times are there to fix save game bugs :/

Also is there a possibility that you ever create lite-version of the mod? I have a decent PC with i5 and GTX 1060 but space battles are killing my FPS. Best solution would be removing fighters/transports spawning from larger spacecrafts. It's a shame because i love the land and space battles, they feel realistic, tactical and satisfying as opposed to Republic at War for example where they were too fast and not reallly balanced

I got a GTX 1070 and a i7 8770K + Samsumg 970 EVO and it works fine for me most of the time, only problem for me are hard-crashes and saving times but the saving times seem engine related.
