Having seen LabVIEW used for very precise control by many teams over many years, I'm not convinced that your experience indicates anything about LabVIEW in general. If you can post your simple programs, I'd like to see if you've done anything that might be causing the LabVIEW one to misbehave. (For example, there could be some simple error in your code which results in a cascade of diagnostic messages to the Driver Station, and those messages are quite capable of interfering with timely communication and control.)
