GPU Compatibility
 
 
 

Key blurs and geometry blurs are processed differently depending on whether CPU processing or GPU acceleration is enabled. To ensure that they are always displayed identically, enable the GPU Compatibility (GC) button before you start work on keys, key blurs, and geometry blurs. The GPU compatibility feature is automatically enabled when GPU acceleration is enabled.

You can also enable the GPU compatibility feature when you set your user settings. See, Display & Interface Settings.

NoteEnabling the GPU compatibility feature does not impact final renders, nor does it jeopardize preview performance. It ensures that GPU acceleration is performed in such a way as to closely match how keys, key blurs, and geometry blurs are displayed in CPU grading mode.
