Yeah, I've had the same issue since release. I can usually play for quite a while before it happens. When it happens, I Ctrl+Alt+Del and have Windows force the game to shut down. Then I reboot and restart the game to continue. Since the game autosaves every turn, I don't lose progress. However, it would sure be nice if they would fix it. They probably have no idea what is causing it.

I can say that it happens more when I edit a lot of ships. I have a suspicion that weapon effects in the ship designer may be aggravating the situation, but it's impossible to really tell.

I have Win10 with an AMD Ryzen 5 2600 and 16GB of RAM, and a Radeon 480 with the latest drivers.

I have been having the same issue for months now. It seems to be linked with having an AMD GPU (got a R9 Fury).

Spudbynight what's your video card ?

Hello. Same bug here. I tested the game during the free weekend, and this bug never happened. Then i bought the game and it is when the games started to freeze, after doing one thing or the other. I can't find a cause, but if i run steam in offline mode, then this happens maybe 1 time, then the bug doesn't happen in hours.

Hello again. Definitely something is wrong with the game, because the bug is happening more and more frequently,  to the point i am getting really pissed with the constant alt+F4 and reload. Can anybody point me to the closest tech support agent? thanks.

Hello. I found a way to stop this from happening, but it gives more questions about if it is really a bug or something intended.

I did a check up in all game files integrity, and since them, the game stopped freezing. But i cannot be sure, because i've been playing online, and i had the issue both when steam was in offline and online mode. First thing i thought was the cause of game freezing was online, due to a conflict with the serial number, since i bought a cdkey in official store, but i had the feeling it could be shared with someone else, yet. But now the game is running smooth again.

So it went this way:

Installed during free weekend promo "endless space 2"-> game ran smooth.

Promo weekend ends, game is locked. Then unlocked with cdkey -> freeze bug

Checked game files integrity -> bug vanished, at least playing 24h without more freezes.

Hope this throws some light over the issue.

That can't be it, because I verify file integrity regularly, and I have reinstalled the game a few times due to upgrading computer, etc. I also purchased the game at launch.

Having the same issue, it is truly a pain. Would very much like any situation anyone has on the matter, short of a fix from the devs (but considering the bug is a bitch to reproduce, i am not holding my breath).

Is that really a bug, or a consequence of my bad machine specs? By doing what you said, do i really get rid of this bug or... its innevitable since IDK how the game even runs on my machine? :(

I have an excellent computer, and this bug has plagued me since the game was released, so it's not your computer.

As long as I remember there were issues with AMD Radeon drivers in  the past, too. Sometimes it was useful to roll back the driver version. Amplitude did reach out AMD for to fix the driver issue in connection with Endless Space 2 and it was fixed. What about to make a new thread and to deliver the requested files listed here Tech support guide ?

Latest driver trouble (not showing some graphic effects in combat) was fixed with driver version AMD 18.5.1, past Amplitude did reach out to AMD.

My guess is, it's worth a try to upload the requested files (link above) when game freeze occurs in a new thread and to roll back to driver version 18.5.1 then to check out.

Or the other way around, to (re-) check if latest drivers (in case of Trifler and ColonelPlastic - the only who offer information about graphic cards in use here) are installed:

Latest driver for AMD Ryzen 5 2600 -> Driver AMD Ryzen 5 2600

Latest driver for AMD R 9 Fury -> Driver AMD R9 Fury series

Two things that helped me (R9 390, Win 10)

- disabling Steam Overlay

and

- running the game in borderless window mode

Switched back to 18.5.1 driver and this doesn't fix the issue.

Also, disabling steam overlay and switching to borderless window mode doesn't fix this either. 

I've just managed to play 10 turns before this happened again. 

The whole thing is very hit and miss. I can play for a few hours without it occurring. Sometimes I can go 10 mins before it hits.

No dice here either. Massive Alt+Tabbing does not seem to affect it either, so I don't think it's related to needing to redraw the screen.

I don't have issues with cooling. I'm running some pretty frosty temps as things stand.

My AV is Avast if that is a potential common factor for anyone else.

No temp issues here. Running Windows Defender.

Today, for the first time, I got a crash dialog box after the game froze up. So, I'm attaching diagnostic files. The directions say there are two places to get the output_log.txt. I'm guessing that means they're both the same? Hope this helps.

I'm still getting this issue. I thought the most recent patch might resolve it.

Yup. Still happening.

I want you to know that we are aware of your reports of freezing issues, both the ones reported here and in other threads or on the Steam forums.

However, from what I can see, we have so far not been able to reproduce the issue, which makes it very difficult to pin down the source and fix it.

Is there anything we can do to help?

To the current day, i still have the bug. More than ever, lately, to the point is turning into a hell to play a match with friends, not to say alone. Freezes every few turns, by any reason.

Months ago when i started, i believed i had discovered the reasons that freeze the game in my computer:

- upgrading heroes from the pop-up in the right side.

-Updating many ship templates too fast.

-Deleting a ship template while i had it in queues on systems. (that is very logical to cause a crash)

For a time, i avoided to do any of these things and it worked.

But currently, i get freezes when:

-Zoom in a system.

-Zoom in a system and i see the initial cinematic that shows every planet.

-Declare war.

-open the empire screen (F1).

-Move a fleet.

-start a battle.

-more...

My computer hasnt changed, all same components.

I don't have AMD, by the way.

Somewhere i saw that it may be caused by DirectX. I run windows10 64, 8 gb ram, integrated graphic card Intel, core temp not going over 38g ever, the machine is simply fine. I have both DX10 and DX12. Tried to reinstall DX12 but i cant download it from official site because it is advertised as a fraud/dangerous web (lol).

And the most relevant detail is that this issue happens only with Endless 2, i have many other games that are more demanding in gpu and ram and they run always smooth! 0 graphic issues with them.

I am very sure that the cause is not hardware. Maybe a software issue, trouble with DirectX, or a fatal error in ES2 code (with all due respect to the team ^^). But when all other games work fine, all other software (not game) works fine, i never have a graphic issue ever with anything, and other strategy games that handle tons of units and memory is required for them, never fail, then one begins to worry about the game itself.

And i am sad for saying all of this, because i recently bought all DLCs, and Endless 2 is a great game. But lately... unsuffearable to play even a fast game vs 4 AIs... the game freezes too much.

Happy 2019 to everyone.

OK, while looking around for a solution to this issue I found this thread on Steam which suggests the problem is a directX issue.

https://steamcommunity.com/app/392110/discussions/0/1700542332324058285/

I have added " -force-opengl" to the launch options and so far, the problem hasn't occurred again. 

I have had the same problem and indeed the "-force-opengl" option fixed it. However it did give me a few graphical glitch during combat animation in scan mode. Trying different things at this point. If none works I'll put back the "-force-opengl" and just skip all combat animation.

I've been playing the last few weeks with the -opengl command and the issue hasn't appeared again.

It does appear to be some issue connected to DirectX
