AMD just released the AMD Catalyst 12.6 Beta. With the release of the Catalyst 12.6 Beta driver, AMD would also like to announce that we are moving away from our Monthly Catalyst release plan. Our goal is to ensure that every Catalyst release delivers a substantial benefit to our end users; as we have today with the release of the Catalyst 12.6a Beta. We will still continue with the Catalyst naming convention; Catalyst: Year.Month., You just won't see a new driver every single month. We are confident that this will only benefit the end user; you'll only need to upgrade to a new Catalyst driver, when it makes sense.

We would also like announce the introduction of our new AMD Issue Reporting Form. We made a number of improvements to the older Catalyst Crew Feedback form, making it more comprehensive, ensuring we get the best feedback possible. Feedback is very important in every product company's life, especially in our fast paced environment. This is not just a check-box for us - we take these reports very seriously. We will review every report posted here and investigate every issue encountered. Please use this form whenever you encounter something worth mentioning.

This is what they had to say, "Covering its back and yours, Bethesda recommends that you only install the patch if you're affected by issues fixed in the patch, and that you backed up your saved games before installing the beta. If you're still ploughing ahead with it, here's what to do:

1. Log into Steam
2. Click on Steam in the upper menu
3. Select Settings
4. Under the Account tab, go to the Beta Participation section and select Change.
5. A drop down menu will appear. Select Skyrim Beta.
6. Select OK.

Steam will now restart. After Steam restarts, Skyrim will be updated to the Beta version currently available.

The beta patch adds an option for Skyrim's Steam Workshop, a portal which will allow mod makers to upload their creations directly to Steam, but the Workshop won't work it and the mod Creation Kit actually launch later this month."

Microsoft has revealed the top 20 most popular games played on the Xbox 360 in 2011 based on numbers of unique users logged into Xbox LIVE (Silver and Gold members). Note that this gives a different result to the total playtime for a particular game, which has not been disclosed here. Unsurprisingly, the Call of Duty series dominates the chart, but what is sure to irk CoD detractors, but make fans very happy, is that a massive five of those positions are taken up by CoD - that's 25% of the rankings. Even CoD4: Modern Warfare which was released way back in 2007 sits at a very respectable number 14. However, top games Battlefield 3 and Skyrim did very well nonetheless, sitting at five and six respectively, with only Halo beating them at number 4. Can you guess which CoD game hit the top spot before looking at the chart?
