In all the years I have been gaming I have, fo the most part, played at whatever resolution was default for my monitor. But I feel that this is probably not the way to necessarily get the best from games but again, for the most part they have run pretty good at that res. But given my spec (in sig) and games such as the one I am just starting COD Black Ops 3 where I have the resolution set at 3440 x 1440 and settings on high. I think it looks and feels OK but at the moment not convinced that my settings are correct. Any advice welcome.
