In this video I’m fixing the exact RX 6600 problem I was facing: even on low settings in Fortnite, I was getting around 54 average FPS but the game still felt laggy, stuttery, and honestly not playable. The big issue was FPS drops caused by the GPU downclocking. So I show you the AMD Adrenalin tuning changes I used, step by step, and yes—this actually works if your RX 6600 isn’t boosting properly. I go into AMD Adrenalin (update it first), then Performance > Tuning, switch from Automatic to Manual (Custom), and enable GPU Tuning + Advanced Control. My settings: minimum frequency 2273 MHz, maximum frequency 2556 MHz, and voltage 1150 mV—this is the important part that helps stop downclocking. Then I enable VRAM tuning + Advanced Control, set memory timing to Fast (don’t leave it on default), and push max VRAM frequency to 1900 MHz. After that, I turn on Fan Tuning, disable Zero RPM, and set Power Tuning to +15% power limit. After applying, my FPS went from ~54 to ~68 average, and the gameplay felt way smoother with no lag like before.
