my friend introduced me to vulkan thhat increases FPS while playing dota 2 before driver 16.10.1
i tried, and it did! my fps went to 50-60 on preset number 3 from the left.
all works fine until Crimson driver update 16.10.1. the brightness is too high (even on lowest possible in-game brightness)
the problem still persist wit the current driver 16.11.3
