That's good to hear. It almost has to help a little bit, so in theory it doesn't matter if you can notice it or not. Some of the lag is caused by the device needing to move data around on the flash memory, so it might not help much in those situations.
For the guys talking about smartreflex, it looks like I programmed the module to do a smartreflex recalibration every time you change the settings. I manually override the existing smartreflex optimized voltage in kernel memory at first to trick it into changing to the voltage you specified, and then ask it to recalibrate itself a moment later. It sort of works, but there are a bunch of smartreflex settings that I could never figure out properly. Sadly this stuff isn't documented very well, and since this is all a hack there isn't really a 100% correct way to do this stuff. The kernel source actually changed a lot right before and right after the version we got on our phones, so I can't just copy the logic from somewhere else.
