After I close out and restart, without fail, the framerate dives precipitously, into the single digits and teens, with low CPU and GPU utilization. I have a Asus s17 I'm running it on and the performance is fine when I initially start the emulator (can get 60fps in most titles, pushing 1440p-gpu is rarely the bottleneck though).
The emulator has a serious problem in terms of performance degradation.
