I opened gruntz on my windows 8 64 bit laptop.The main menu runs with normal speed.But when i starting level,game runs with several fps.I need to waith 13-20 second to control a grunt.

This was discussed before. Basically, if Gruntz is running slowly, then you need to use a certain program to make it run in a window. Here is an explanation: gooroosgruntz.proboards.com/post/22464/thread

If it happens that the game crashes when you walk onto a checkpoint, then you can find an answer below the linked post.
