That is a limitation on gif decoders, most won't playback at more than 50fps!
You can see the behaviour here

My suggestion would be to render the frames to images and apply a more complex
ffmpeg filter. If all you want is double the speed render the animation frames
as images and try:

Create a palette
ffmpeg -r 60 -start_number 0 -i myanim_%04d.png -vf palettegen -y mypalette.png

Make gif
ffmpeg -r 60 -i myanim_%04d.png -i mypalette.png  -lavfi
"fps=30[x];[x][1:v]paletteuse" -y output.gif

I'm sorry, but there isn't much we can do about that -- it's ffmpeg that
creates the animation from the frames. You might want to do that manually and
play with ffmpeg's options.
