Parallels has popped out the next major release of its virtualization tool, Desktop for Mac, which lets users of Intel-based Mac systems seamlessly run Windows applications. Version 4.0 claims to improve OS integration, performs up to 50% faster and incorporates a redesigned user interface and over 50 new features and improvements in total.

This release also improves battery life by a claimed 20% when using Parallels on a notebook, adds 64-bit support and the ability to make better use of multi-core processors. Graphics performance has been improved as well with added support for DirectX 9, DirectX Pixel Shader 2.0 and OpenGL 2.0 though the company admits hardcore gamers are better off using a native install.

Parallels Desktop 4.0 costs $79.99 but users can test a free, fully-functional copy for 15 days. Existing users can upgrade for $39.99 until the end of November or $49.99 afterwards. Check out the full list of new features over at the Parallels site.
