Unsolved N64 Lags

[SirSpawningham]

Hello, i have a problem. I use Recalbox on my Raspberry Pi 5 with 8GB ram and i have ingame lags. I already tried to fix the problem in the retroarch menu, but it didnt work out. I read some threads of people with the same problem, but i couldnt find a solution. For Power supply i use the 27-30 watts adapter from Raspberry. Thank you for helping me
