Small update. I've had sessions where I have not had major problems and played fine, although CPU usage is still high, especially on my third core (90%+ while other cores are <60%). However, I have encountered several nasty issues this weekend.
1. Crashes to desktop while the game was paused or running (error report sent) where all my monitors went black and then came back.
2. Crash moments after starting the launcher (error report sent) resulting in monitors going black again and coming back.
3. Launcher crash where the program was still running, but no longer visible, had to force stop it in task manager.
4. Launcher was
always slow even at release and it was always hard to select things (e.g., mods, DLC, clicking play button). Now it is worse than ever. Having more mods selected in the launcher makes it run slower. I
reported this back in May during 1.6.1 since I was finally fed up with it. This doesn't occur in the EU4 or HoI4 launchers. Something is
really wrong here guys, this thing should not be using 50%+ of my CPU.
5. Whether at the main menu or while in game playing, I have these odd sound glitches where everything on my computer stops -- it's like a total freeze -- and the sound loops (e.g., music, selecting a fleet, opening a menu) yet I can resolve the issue by moving my mouse into a different monitor, essentially outside the program, and the glitch ends as quickly as it started.
None of these issues were present (except the slow launcher) in previous versions of the game or the betas I tested. Although I have many mods enabled, they had never been causing problems like this either. My system is an i5-4670K, GTX 1060, running Stellaris on an SSD, triple monitor setup, with Windows 10 64-bit.
Other than that, 1.7 is looking good and I am quite pleased with the patched features and new content.
