Un-playably laggy game on Ubuntu platform

  • updated
  • Declined

Higher number of AI players / computations (pretty much any campaign mission with 2 or more AI's) = an un-playably laggy game with constant freezes and stuttering.

Building rooms literally takes several seconds per tile to build.

Minions jump around on screen, I guess trying to catch up with positional information.

Forget about trying to open the game menu or use the UI, that takes around 10s to respond.

Hello FooBarBlarg,
the next patch comes with some remarkable performance improvements and the problem that units have issues reaching their target in lag situations will be fixed.
But not sure if it will fix your issue to full extent.
The slow UI issue on the other hand, might be entirely fixable but needs trying.
We found several specific hard and software configurations having this problem.
Can you try to start the game with launch option "-force-d3d11" and see if the UI is more responsive?
If not you might find more things to try over here:

I hope that helps.


I'll give this a try and get back to you.
