 ### Upscalers
 OptiScaler supports DirectX 11, DirectX 12 and Vulkan APIs with multiple upscaler backends. You can select which upscaler to use in the `[Upscalers]` section of the `nvngx.ini` file.

+`No syncing` : Self explanotory  
+`Fence` : Sync using shared `Fence`s (Signal & Wait). These should happen on GPU which is pretty fast.  
+`Fence + Event` : Sync using shared `Fence`s (Signal & Event). `Event`s are waited on CPU which is slower.  
+`Flush` : After Signal shared `Fence`, `Flush`es Dx11 DeviceContext.  
+`Query Only` : Uses Dx11 `Query` to sync, in general faster that `Event`s but slower than `Fence`s.
