This was an old issue that i posted a long time ago, but i think the original thread was deleted so im reposting an update.
originally the launcher took more time then minecraft to load. but since i updated to windows 8.1 the problem went away (i also updated to java 7 update 45 on 32 bit for chrome and 64 bit for running minecraft, I'm not sure which fixed it, but if you have that sorta problem and you are running windows 8 you should look into the latest version of java and updating to 8.1 as a fix.
