Never had a problem with this before, but it's becoming more of an issue. Games where I'd be able to take pics all day long, now have a split second pause / lag / stutter introduced when taking a shot. Holding down the screenshot button will make most games go into a wave of choppy / jerky freezeframe animation, some more affected than others. Payday 2 is now so bad that pic taking can in some cases freeze the game entirely for a few seconds, instead of "just" making it choppy for a split second.

In terms of playing the games themselves, there's no problem at all - they all work fine on good / high / maxed out settings. The only problem is screenshots, which is a little odd.

Any suggestions welcome.
