Final Fantasy IV : The complete collection

[[Unknown]]

And by first battle - you mean in the intro, in the airship? It's not crashing for me, at least not in a recent git build.

Try switching to Direct3D 11, or Vulkan. Does it crash in both of these backends as well? Make sure you have hardware tessellation disabled. I'd also recommend looking for video driver updates.

Unfortunately, I don't have any AMD video card to test with - I'm using an NVIDIA 9xx.

You may also want to verify the crc of your disk image and re-rip it if necessary.
