While running Hollow Knight Silksong my ONDA B760ITX-B4 motherboard has wild frame rate curve swings is the stress test not done properly and needs proper bottleneck quantification

Pushing through tough levels in Hollow Knight Silksong the ONDA B760ITX-B4 motherboard keeps showing clear frame rate curve swings that throw off the rhythm. Community posts mention the same thing happening on similar setups. Launch AIDA64 system stability test pick the FPU and cache options and let it run a full thirty minutes while logging temperature and power curves. Once finished export the complete report confirming bottleneck quantification data is spot on accurate. Cinebench cross check shows multicore scores holding steady in the expected range. PCB material durability test passes thirty nine hundred hours with zero issues. Memory speed stays locked at 5600MHz cycling smoothly. After tweaks screen smoothness jumps noticeably. Overall performance evaluation conclusions come out solid and backed by real numbers.
