video stutters

I'm new to Switchroot and am currently using A11TV beta 2 on my erista switch. I am getting frequent stutters whenever I try to watch content on apps like Netflix or HBO Max. It's normal for a few minutes, and then brief bursts of video stutter start, mixed with moments of normal video. This is also Widevine L3 content, so 540p at most. Are these bugs related to the beta, or are SD cards just that much slower? I also tried performance mode in Switch configuration and it didn't help. This is a fresh install of the beta
