How to calibrate Onda real-time monitoring for Returnal?
Playing Returnal in high-load combat zones, my Onda chipset was fluctuating between 56°C - 62°C, and the fan noise was getting pretty aggressive. The frame time graph had these disgusting spikes that were visible to the naked eye. I first tried cranking up the sampling frequency in my FPS monitor, but while the data refreshed faster, the actual smoothness didn't improve. I then used a hardware sensor tool to track frame time deviation and found jumps in the 12ms - 18ms range, which was causing blatant screen tearing. I realized the sampling and rendering were totally out of sync. For my second attempt, I tweaked the frame limiting policy, and the curve finally started to flatten out during stress tests. I still had some minor jitters, so I layered on V-Sync to lock it down. Tuning real-time monitoring is a tedious process. Stable frame times require a multi-pronged approach; you can't just change one setting and expect a miracle. The airflow in my case was creating some weird wind noise, and my peripheral latency was floating between 10ms - 15ms. Finally, the calibration tool confirmed the sampling rate was locked in. It took a minute to settle, but the monitoring is pinpoint accurate now. This is the way to go for Onda boards.
