I just bought an rx 6600 , just installed it and played csgo/lol/ark survival evolved , in all of the games I did not have 99% gpu usage and even tried to max out settings in ark survival evolved to get the gpu to work more and in league of legends with max settings I only had 90~ fps.The gpu usage is at 40~ or something. I have an i3 6098p with 12 gb of ram , ready to provide more information
