HI,  
  
  
  
  
  
I have a specific pb with my iPad2 when i use a “big” varying value.  
  
  
  
  
  
For example, a value ranging from 10005 to 10000, the variation is smooth on iPad1, while the value iPad2 passes abruptly 10005 to 10000.  
  
  
  
  
  
Here’s a link to an archive of a Xcode 4 project based on the opengl template which demonstrates the problem:

Thank in advance.
