Can I fix RX 7650 GRE frame drops by changing priorities?
Honestly, feeling frame drops on a 7650 GRE in Metro is almost a joke. In the dark, moody underground sections, my average FPS was around 80, but the 1% lows would suddenly crater to 25 FPS, making the movement feel choppy and weird. I tried killing every background app, but it did nothing; the drops were still random, which told me the CPU scheduler was just sleeping on the job. I went into the Advanced Power Options, cranked the minimum processor state to 100%, and used a utility to disable core parking entirely to keep all cores awake. In the RTSS frame time graph, the jagged 'EKG' lines finally flattened into a straight path, with lows staying above 60 FPS. The downside was that my idle power draw jumped by 10W and the fans started humming, until I set a custom fan curve to quiet them down. CPU temps sat between 52-58℃ with a perfectly even load. I exported the frame time data for the tunnel scenes, and the fan speed stayed locked at 1400-1600RPM.
