I noticed this on 4 different machines:
Galaxy S8+ (Exynos)
Galaxy S9+ (Exynos)
I5+RX480+HDD 7200 + 8GB DDR4
I7+GTX 1060 + SSD + 16GB RAM
Every time I install a fresh copy of dolphin it swaps between laggy and smooth for the first few times, then it starts to go full speed (within their technical limits).
At start I thought about throttling or ram usage problem but I realized that this happens only on the first plays.
