What's new in this version:

- Large improvements in video recording performance (with vsync disabled)
- Fixed problems with recording on systems that have virtual surround software installed (like Nahimic)
- Improved high bitrate AVI recording on systems with hybrid hard disks (SSD + HDD). We still recommend normal HDD or SSD for high bitrate video recording
- Browser overlays now accept keyboard input (for example you can logon to YouTube to allow YouTube chat overlay)
- Fixed Action! not working properly from certain disk locations
- Audio/Video desynchronization when streaming during high CPU usage has been fixed
- Fixed frame stuttering when recording video from Elgato/Hauppauge and other devices that capture MPEG-2 transport stream
- Fixed AVI freezing during high CPU usage
- Fixed webcam stuttering during high CPU usage
