| Metric | Legacy Driver (v3.5.2) | New Driver (v4.2.1) | | --- | --- | --- | | Max frames/sec (1 channel) | 8,200 fps | 14,500 fps | | CPU usage @ 10k fps | 12% | 4.5% | | Min latency (send to receive) | 210 µs | 48 µs | | Linux kernel crash rate (5.15) | 1 per 48 hrs | 0 per 200 hrs | | Python API init time | 1.2 sec | 0.08 sec |
Perhaps the most user-facing improvement in this release is the software ecosystem. In the past, using niche diagnostic tools often required navigating a labyrinth of 32-bit DLLs, obscure registry edits, and incompatible API libraries.
The new driver finally provides proper DKMS integration. This means the driver survives kernel updates.
: Check your computer's device manager or a similar tool to ensure the device and driver are recognized and installed properly.
