After Kill Renderer, (if V-Sync is enabled) fast forwarding is no longer able to exceed V-Sync in Vulkan and OpenGL. The result is that with V-Sync enabled, Vulkan and OpenGL are able to fast forward up to the panel's current refresh rate, but cannot surpass it. If V-Sync is disabled it still operates normally. Theoretically, Dolphin can no longer disabled V-Sync in Vulkan and OpenGL, but I didn't test that far.

D3D11 and D3D12 are unaffected. Metal is unaffected. MoltenVK is unaffected, probably due to being translated to Metal. OpenGL on macOS is affected.

To reproduce, turn on V-Sync and hold fast forward while using Vulkan or OpenGL.
