Games have framerate drops when using Parallel

Games like Super Mario 64 and Majora’s Mask have framerate drops when using Parallel, and the fastforward key doesn’t work. Only by fiddling with settings does it run fullspeed and can fast-forward.

I’m using the latest stable version (1.3.6) and have a GTX 970 and i5 4570

Okay so I just tried it again with the settings I messed with, even frame delay. To get it to stop stuttering I had to close the game itself then reopen it. Retroarch was open all throughout the test
