Quick summary

Both Gundam: Crossfire/Target in Sight and Gundam Battlefield Record UC 0081 (both games share similar engine) runs smoothly at first, but several days later the performance keeps dropping until the FPS reaches 15-10 FPS even if I don't open the emulator at all.

This problem occurs regardless of emulator version and settings, tried with v0.0.7 all the way to the latest build. Could this be a specific issue to Ryzen 5 series processor?

Details

1. Open RPCS3
2. Launch game
3. If the game boots at 60 FPS, it'll run consistently at 40-60 FPS until you close the emulator
4. Quit RPCS3 and/or wait for several days, then start the game again. Chances the game will run at 20-30 FPS.
5. Repeat step 4 until the game runs at 15 or lower FPS.
