Yeah, that sounds about right. My device(Alcatel 7 with 8.1 Oreo) has a pretty decent Mediatek processor(Helio P23) and I've noticed that Vulkan is a bit slower than OpenGL with PPSSPP too.

Mediatek aren't really involved in the 3d drivers - the Mali driver in the P23 shares literally zero code with the PVR driver in the mt8176 in the gpd xd+.

The problem with mediatek is they never update their drivers from the initial "bringup" ones Tongue

How come ppsspp has no issue when using Vulkan backend though?

Is there a chance to fix the crash?
