For me, bezels are very important for my setups. I really wouldn't want to make systems if I wasn't able to get custom game specific bezels made for all the black border content, I despise black borders, and I despise stretching....so some sort of bezel is needed, and I always would want game specific art over a 'curtain' type solution.
So I've found Launchbox with Rocket-launcher a must, and I am fine sacrificing performance for this. If Launchbox had bezel and pause functionality my need for RL would be probably be gone.
