Description

When dumping textures, Dolphin uses the default compression level for png’s which is 6. There’s a ton of overhead in this causing a lot of slowdowns. This feature request simply asks that this option be exposed.

I have my own solution for managing png compression so I’d prefer it if I could set it to not compress at all. I mentioned this to @iwubcode and he pointed me to this line:

I’m currently building my own copy with the change and FMV’s no longer slow down. It runs pretty much full speed all the time. https://youtu.be/HkVJEMBNGUQ?t=161
