4. Performance Benchmarks & Stability Improvements

Early adopters have reported measurable gains. Using a standard Windows 11 Pro test bench (Intel i7, 16 GB RAM), here are the comparative metrics:

| Metric | v1028a | v1028b | | :--- | :--- | :--- | | Cold start to ready screen | 8.2 seconds | 4.7 seconds | | Memory usage (steady state, 4 channels) | 1.4 GB | 890 MB | | CPU usage during burst logging | 34% | 19% | | Session crash rate (8 hr continuous) | 1 per 36 hrs | 0 per 120 hrs* |

*Based on internal QA and three third-party verification labs.

Notably, the update resolves the infamous “DTC overlap bug” where two conflicting diagnostic trouble codes from different modules would cause the software to hang during report generation.

✅ Supported Operating Systems (Updated)

  • Windows 10 (21H2 and later)
  • Windows 11 (all builds)
  • New: Ubuntu 22.04 / 24.04 LTS (native, not via WINE)
