How do I speed up Blender Game animation? I am using the Blender Game render for keyframing physics, but when I play it back, it is so slow (the keyframes are close to each other, the closest they can get, but it is still slow). Is there a way I can speed this up in the graph editor?

Also, and unrelated question:
After I keyframe with Blender Game, can I go back to Cycles Render without affecting the timeline?
You can speed up the playback of the animations by increasing the 'Animation Frame rate' speed in the Render properties editor.
