Slowdown with beetle Saturn

[housello]

Hi, I noticed that framerate drops when using mega bezel with beetle saturn core. I use vulkan driver, and the emulator slows down even if I use the passtrough preset. Cpu and gpu usage is very low, and the slowdown doesn't happen with any other shader (even royale), so I suspect that there is some configuration/function conflicting. No problem with any other core.

I'm not sure what might be going on, the fact that you'll are getting slowdown but the CPU and GPU usage is still low is quite strange

sf3.zip I attached an example: in the image you can see shining the holy ark running at 57fps, with cpu and gpu usage not at 100% I also attached a verbose log file launching shining force 3 with crt-aperrture, then changing to megabezel.
