"In the last few days we have seen an incredible outpouring of interest in AOE: II HD Edition and we are thrilled to see gamers re-living some amazing experiences from the past decade. We do, however, recognize that some players are experiencing issues and we want to talk about what we're doing to get some of these resolved.
If there was any question of "are we going to put out a patch", the answer is 100% yes. Since pre-purchase access, we've been working to identify some of the issues players are having - with trying to sift through all of the posts on the forum similar to drinking from a fire hose. We did immediately get to work on resolving some of the compatibility issues around Windows XP and our implementation of some Steam technologies. The first build update to resolve those issues (and a few other launcher crashes people had reported) was released on Monday night.
Right now the biggest questions we're seeing is around game performance for some players such as frame rates (specifically on high end machines) and multiplayer connectivity. These issues are specifically where Hidden Path is focusing and they are working to reproduce and resolve them. One of the many challenges with old code is that some of the processes are actually dependent on the fact that older computers take a much longer amount of time to calculate information, creating potential snags all throughout the rendering pipeline. We may from time to time ask users to post or send us their system configurations / dxdiag, etc to help identify what hardware types we'll need to reproduce and alleviate issues on.
Priority #1 is to improve the performance for players reporting sluggish gameplay. At the same time we'll also be making some adjustments to multiplayer to improve the experience there further and help identify what may be causing gameplay delays. Please be aware that this is a peer-to-peer game which means your multiplayer experience will depend on the quality of everyone's connection. If 5 people in a game have 40ms pings and someone half way around the world joins with a 400ms connection, it will result in a suboptimal experience for everyone.
Resolutions we make for frame rate and connectivity issues will be moved to the public as quickly as possible while we continue working on other identified problems like quick match crashes, localization bugs, and trebuchets. We will also be working on some of the game features that you have asked to be improved such as quick match game speed, mouse bounding options, regional lobby lists, and more. This is no means an exhaustive list, but we are working as fast as we can and are very much listening to what you are saying."
