In certain situations like this, you can insert lines without them already having defined values. Many features the engine offers rely on default settings that aren't explicitly written in the file. I'm not sure which file this is, but my best guess is TdEngine.ini. Although the link above shows both "bSmoothFrameRate=True" and "MaxSmoothedFrameRate=62" in that file, the key points are that you need to adjust one of those parameters. You should either disable frame rate smoothing completely or increase the maximum smoothed frame rate.
