Are u testing this with cracked / pirated games? Because the DRM like Denuvo makes game a much heavier then cracked / pirated games (Sorry for bad english)
I built a 5600g for my wife very close to what you have except I have dual channel 32g 3200mhz, if you go into the bios dedicate 50% of the ram to graphics enable resizeable bar, you might have resizeable bar enabled already but dedicating system ram to graphics will greatly improve your gaming. Good luck with it, don’t exceed more than 50% of system ram to graphics.
