probably just hardware but anyone else, have to stop at around turn 100?

yep, need to restart the game around every 7 turns. It started around turn 100, maybe a little earlier

I saw this too.

Yep about turn 100 every time.
I found turning autosave off helped push it out to about turn 130-135

Was about turn 115 for me, just as the last AI empire became visible. I have to save and restart every 4 turns

After turn 100, happens to me. The more turns are played, the faster I have to reload my save.

I have a 8700k and 1070 gtx (full list), and doing fine 2/5 game on ultra setting and 2k resolution. There's something happening in later turns. I only really had issues of anything like this once I sailed to the next continent which had 4 more civs on it. My original island is mostly conquered. I've also noticed I really only run into issues when I have battles. and i think even more specifically when I have more than one battle open. 

I do have quite a bit of live map open due to scouting heavily across the globe, but really only run into stutters then failing stalls after going into battle. Even with smaller one turn and done armies. 

I also have a slowdown in later game. It started around turn 95. If I save and reload, the game runs fine for a few minutes.

After a while I get a clattering sound that sounds like a wheel of fortune that is slowing down till it stands still.

From this moment on everything takes 10+ seconds to happen. Popups, mouseclicks etc.

Turn 95 on my second time through was the first time it happened on that one. I think it may have to do with the amount of map open. As I progressed further after the first instance in my first playthrough, it came as often as every two to three turns. Audio cue that it starts sputtering into a slow down, quickly save and reload to reset.

look at your diagnostic files and post them - trace may indicate an intervention/ critical error

Well at my game it started at Turn 80 or so game sound drops and one or two seconds later the game freezes.

Quicksave every turn but I don't think I will get through with this pace.

Same with me, need to restard after a few turns past turn 100.

I have to restart every 20 minutes,  I am never even close maxing out my cpu, ram, and graphics (I turned graphics down too, after the first crash) The game just doesnt seem to be able to stay stable after turn 100 or 120.
