I played the game using the demo without issues. I purchased the full version and started the campaing New Hope.
Everything works fine, until I place the first item of the game: the lab. Here the game slows down so much it's nearly unplayable. As long as I don't place the lab, game is running fine.
I'm using Windows 7 64bits, on Intel Core2 @2.66 GHz, 4 Gb RAM, GeForce GTX 750 Ti, running the game with Vista compatibility mode because of the SP1 issue.

Thanks.

I have another computer running Ubuntu 14.04 32b which has similar CPU but slower graphics card. There is no issue there.

Hope this helps.

Can you post a screenshot of the debug times? Press F4, enable the update times option then press F5 to show them and take a screenshot of that.

Does it happen only when you have the lab on screen? Did you update your drivers etc? Can you post the log?

Btw, why don't you have service pack one? The problem is probably related to it, just install the service pack.

Edit: Apparently, the bug is really related to the missing sp1, so I'm moving it to resolved bugs.

The issue is still present after I installed the W7 SP1.
I'm not sure someone will read this reply as it's in the "not a bug" forum, but in case, here is an imgur album with the requested screenshots:

Script Update times goes from 0.17 to 21.8.

Now, you gave me some pointers

I will take a look at it.

Well, there is some small script non-optimality in this phase of the campaign, but I didn't get more than 1ms on script update on my computer anyway.

I optimised the script checking for the technology researched, so the script update is 20 time less for me (0.05ms insted of 1ms), so it should probably help in your case as well.

P.S. Don't you have some mod with bug amount of technologies activated? In that case, I could image it was happening.

I don't have any mod.
Do you want me to install the optimized script manually to check if it's better? I'd be happy to try.

Thanks.

After another check on windows update, another SP1 update got installed (cf my updates history: http://i.imgur.com/pckkJ6R.png . As you can see here: it's the same KB number, but different installation date).
Anyway, sorry about that but this fixed the issue actually.
