 | `Uint64 IRenderDeviceD3D12::GetNextFenceValue()`              | returns the fence value that will be signaled by the GPU command queue when the next command list is submitted for execution |
 | `Bool IRenderDeviceD3D12::IsFenceSignaled(Uint64 FenceValue)` | checks if the fence value has been signaled by the GPU. True means that all associated work has been finished |
