Is your hardware monitor lagging behind the actual gameplay?
I originally blamed overheating, but the default sampling in HWiNFO was too slow, showing data from 3 seconds ago. In a Win11 23H2 environment, I forced the sensor polling interval to 500ms. Comparing the data streams, I found the 'smooth' curve actually hid several instant peaks above 85℃, the true cause of the drops. Verified via GamePP, the sync latency is now under 100ms, aligning perfectly with the frame hitches. Just a heads-up: this high polling rate eats about 1% - 2% of CPU overhead, which might be noticeable on very old budget chips.
