For the "quiet" games, try increasing the Windows volume, if it is not already at 100%. Running the O2 at its maximum volume setting at low gain is not a problem, by the way. If you cannot get high enough volume in other ways, then use high gain, if those games are really so quiet, then perhaps it will not clip. Other than the risk of clipping, setting high gain increases the measured noise and distortion of the amplifier, but in practice clipping in the gain stage is the most important (and audible) issue if it does occur. Ideally, you should increase the digital signal to a level high enough (without digital clipping) that low gain is sufficient.
