Change Log

• 1.003: 31/05/10

  - All: Denormal high CPU utilisation fix for some systems.

  Download PC Native, Download PC GPU Edition

• 1.002: 01/05/10

  - GPU: Updated to CUDA 3.0 to enable increased separation of CUFFT and CUDART libraries from other CUDA applications within the system. The CUDA convolver now uses page-locked memory for slightly higher but more consistent CPU usage.

Known Issues

• A potential bug in energyXT 2.5 appears to cause VST plugins' destructors not to be called when they are unloaded see http://www.kvraudio.com/forum/viewtopic.php?p=3394932 see 08Aug18 this results in resources not being released properly.
