First of all, thank you very much for releasing this patch and allowing us to enjoy the game. But, I feel the need to make an important point in behalf of all the folks out there (including myself) that play on a single core machine. In so doing, I'll try and be as constructive as possible.
Despite the fact that the minimum system requirements can appear quite vague to the end user (Intel Duo Core or equivalent- Nathan clarified that this refers primarily to dual core machines, but it's very easy for that statement to be misinterpreted), I'm currently playing on what I'd consider to be moderate video settings, and the performance is practically flawless. Granted, I haven't gotten very far as of yet, which in turn opens up the possibility that yet another bug could rear its ugly head, but everything is good so far. I was also able to enjoy Dragon Age: Origins without a hitch, and once the patch was released for the Mass Effect 2 bugs that plagued single core users, I played that as well without a problem.
The point I'm trying to make is this: despite the fact that the last two titles you've released have been primarily for dual core audiences, as explained when someone examines the system requirements that are printed on the boxes, you apparently have a large base of users, myself included, that enjoy playing them on single core computers. This is further exacerbated by the fact that they tend to run so smoothly, which, interestingly enough, is a testament to the degree of talent your programming and coding teams have. While there certainly isn't anything wrong with taking advantage of the more recent advances in computer technology- in fact, it's encouraged- this particular incident, when viewed in the light of what took place when Mass Effect 2 was released, could give one the impression that those who enjoy your titles on PCs with a single core processer are somehow less important than, or aren't viewed in the same light as those who have more powerful computers that utilize 2 or more cores in them, even though such persons make up a good sized portion of your fanbase.
And then there's the rest of the year 2011 to consider. Later on, Bioware fans will be treated to two of the year's biggest and most anticipated releases. Since single core users have now twice been subjected to bugs that have been serious enough so as to render their games unplayable, at least for a period of time after launch until an official patch is released, maybe Bioware developers need to reconsider their programming approach when it comes to single core machines, perhaps coming to the realization that there are many more out there that use such computers than they think. It would be a shame if we had to endure such game-breaking problems all over again because it would sully the reputation that you have for releasing quality titles. If there were a greater quality assurance focus towards those that use such PCs, whether it be because of budgetary or other reasons, then the chance that we would have to suffer and endure such a difficult situation would be diminished.
*Note: yes, I do realize that there are others out there with dual core computers that are experiencing these same problems. However, the nature of this particular bug, Nathan's response to it, and the mechanics of the bug fix make it apparent that it's very much single core related.
