  • Profile scanning currently reads every profile through a fixed 512-slot buffer, even though most profiles only have a handful of settings. Each slot is ~12 KB, so every profile incurs a cost of moving ~6 MB to and from the driver no matter how much data it actually holds
  • Now sizes the buffer to each profile's actual setting count (retrieved through the numOfSettings property exposed from the driver), so it only moves what's needed
  • During testing, initial scanning was noticeably faster; saw ~19% reduction in scan time.
