i dont think its luck, dolphin wants nvidia. now all games run well, but also all dolphin games running on older dolphin versions run worse than newer ones we have to play on an old tri force dolphin version, i get over 100 fps but then also i get stuttering back down to 49fps up and down fps L A G on the soccer games. it maybe just cache it may not be. all i know is i can play RDR2 in max settings in 4k HDR at over 90fps into the 100's
