We’ve just updated the Steam build with a hotfix to solve these issues, so we recommend you save your game, quit to desktop, and restart Steam to start the hotfix download. This was causing the game to hang too long on start-up and the multiplayer server list to become unresponsive. We’ve had tens of thousands of people playing already, but we know some players had some early-doors issues when the game went live, due in part to a bit of unexpected server load and the way the game handles that. This evening a hotfix has also been released which will hopefully resolve multiplayer and start-up issues.
We will continue to investigate solutions to the load on the servers, but expect the problem to dissipate as launch day goes on. The remaining issues appear to be solved by graphics driver updates and verifying your Steam cache (right click on the game from the Library > Properties > Local Files > Verify integrity of game cache…). In 90% of cases, restarting the game with Steam set to Offline mode will solve the problem.
We had 40k+ people playing the game in the first hour, about unfortunately a few hundred players having trouble getting in. SEGA dropped us an email over to make sure players are aware of the issues which included Earlier today Total War: Warhammer was unleashed on the world and there have been a few issues reported by players.
