Hi guys,Good to hear they're working on more fixes, although I wouldn't mind them releasing it a little earlier.
In the weeks since Total War: Shogun 2's launch, we've been working super-hard to make the Shogun 2 experience as great as we can make it. As part of our long-term commitment to supporting the game, we've been making issues identified by members of our community our top priority.
So, we're planning to roll out some fairly substantial fixes in the coming weeks and months. The first stage of this is Patch 2 which, we're thrilled to announce, will also upgrade the engine to DirectX 11. This means those of you with DX11-capable cards will be able to access features such as hardware tessellation and enhanced shadowing. Patch 2 will also bring Anti-Aliasing support.
Since Shogun 2's launch, we've been completely blown away by the success of multiplayer. However, the multiplayer issues many of you have identified require our thorough attention, so that's a really big priority as well. You can expect a raft of multiplayer fixes and modifications in Patch 2, and beyond.
You'll appreciate that all this takes a lot of time and testing, and while we're working as hard as we can, we may not quite make the 2-4 week post-launch window that we'd originally hoped to hit. We're aiming to get patch 2 to you in the first week of May though, so not long to wait now.
Thanks for your ongoing patience, and please bear with us!
