I have a screen which uses 2 grids and some database pulls. The screen freezes up, even in preview mode.

Is there a way to stop this from happening? I did increase the maximum execution time and the maximum memory.

Are you sure that you don't have any errors in your database queries?
Turn on debug and debug_sql in your env.ini file and check the log file to see if there are any errors.

If you have custom JavaScript code in your DynaForm, turn on your web browser debugger (press F12 in most browsers) and check for errors.
