Hi Felizon89,
It also slows down in all my SP games, so it isn’t an internet or firewall issue. I disabled all of my mods and it was still an issue. My intel driver is up-to-date (version 31.0.101.3889) so that isn’t the issue but I also rolled back to version 30.0.101.1660 and it still didn’t work.
This seems related to the issue I had a few months ago (Game crashing in Castle Age - #23 by SodaPopinski9) but it is different because (1) this is happening much earlier, (2) this isn’t causing the game to crash, and (3) rolling back the driver solved that issue but isn’t working here.
