That stops the 2-3 screens displaying if thats what you're after. Though Im sure I read somewhere there was actually some debate whether it lessened the load time or not. Which brings me onto another point, have you got loads of graphics? (backgrounds/logos/kits etc).
When I put my graphics in the game I left the "use skin cache" unticked and "always reload on confirm" ticked. That was necessary to do so the new graphics would show. However, When restarting the game at a later date the game will always reload all the stuff again which for me took upto a minute of black screen.
If you have got loads of packs in your game, reverse the preferences back to "use skin cache" ticked and "always reload on confirm" unticked. That'll cut your wait considerably.
Obviously, if you add further new content after this point you'll have to swap the "ticks" around again but dont forget to change them back again afterwards.
