IMPORTANT: Please note that the Vertcoin algorithm requires different GPU settings, and that you will attain, at most, 50% of the normal hashrate that you would get mining a normal scrypt coin. Everyone else will also of course have at most half their normal hashrate, so you will remain equally competitive and mine the same "slice of the pie" as you normally would.
In particular, you will need a --thread-concurrency setting of around 70% your normal setting. There is a GPU settings thread at
https://bitcointalk.org/index.php?topic=416572.new#new that may help with setup, and if you are setting up on a GPU type that no-one has posted settings for yet, it would be appreciated if you would post your GPU type, settings and hashrate achieved in that thread.
