Dolphin, the GameCube and Wii emulator - Forums

I've been playing Super Paper Mario for the past few weeks with Direct3D 11 and had a lot of FPS drop at certain point (or rather 30fps lock).However once I changed my graphic option from Direct3D 11 to 12,the game runs 60fps smooth at most scenario. So whats different about these two?

My specs: GTX1060 6GB ,I5 750@2.67Ghz 4 core and 12GB ram

Well, Direct3D 12 is based on the more recent DirectX 12 libraries, on Windows 10 only (Windows 8.x is limited to DirectX 11.2 ans Windows 7 to DirectX 11.1). But don't count too much on it, it was rapidly abandoned in Dolphin's development builds to be replaced by Vulkan. But yeah, Direct3D 12 ran better for me than Direct3D 11 as well...

Disable V-Sync. That will stop the 30 FPS locking.
