The Belle II experiment at the SuperKEKB accelerator is designed to explore the next frontier of flavour physics with unprecedented precision. However, operating at the world’s highest instantaneous luminosity presents significant challenges for tracking and vertex reconstruction due to increased detector occupancy. I will present performance studies of the proposed all-pixel vertex detector upgrade and its impact on key benchmark decay channels. Additionally, I will discuss a technique to mitigate beam-induced backgrounds in the Silicon Vertex Detector (SVD), using a new cluster-timing-based hit filtering algorithm that enhances efficiency while suppressing fake tracks. Improvements in SVD time calibration processing will also be highlighted. Beyond the SVD, I will touch on the real-time efficiency monitoring tools for the Central Drift Chamber, ensuring data quality for the analysts.
