Recently, I found that toggling gamma beyond 100 does not work. Before this update, it is possible to toggle >100 with a success which means that it gives extra brightness. To toggle gamma, go to options and find gfx_gamma and toggle it to for example 15. As I repeated, it is supposed to give full brightness but instead it does not seem to function since 1.1. Please fix this in 1.1.1. Thanks.
