The latest update included G15 support, since then I have had frequent crashing after only a few minutes of playing. I have reloaded the game and disabled it in my Logitech CP but there is no option to turn it off in the game. Aside from the game update it's self I can't think of what else it could be. I am reaching out the community with those who have a G15, have you noticed a more frequent amount of crashing with the beta since they included this feature.
There is another possibility that might be related to this. I also use a G13 in tandem with my G15, Ironclad could this be an issue?
