[Flexradio] More memory?

[Jim Barber]

Have you tried squeezing the PSDR GUI down to its minimum size on the 
desktop and setting the process priority to "realtime"?

At least in my case I've seen those things help as much as anything, 
especially on machines with what might be considered "marginal" graphics 
hardware. (onboard Intel and other inexpensive, memory-sharing graphics 
systems)
