I've updated the beta branch with a full build to address the following issues:

• GI / water bug where everything would get brighter (the blend mode wasn't being reset to "solid").
  
• "Cannot blit backbuffer" bug fixed.
  
• VC .usr file added back into template, which contains info on the default working directory. This is why games weren't launching in the right directory.
  
• SDK version set to 8.1 since the 10 SDK isn't installing on Windows 7 (what I'm on now).
  

FYI, I tested on an AMD card and there were not any AMD-related errors in the previous build.
