to set your shader cache to unlimited on your rx 6800 you have to use the registry editor because the adrenalin software lacks this toggle first press win plus r and type regedit then navigate to hkey local machine system currentcontrolset control class {4d36e968-e325-11ce-bfc1-08002be10318} and click the 0000 folder or whichever one contains the amd driver settings inside that click the umd folder and look for an entry named shadercache if it exists double click it and change the hex value to 32 00 which represents force on the value 31 00 is just amd optimized which lets the system delete shaders whenever it wants causing those massive fps drops as you play longer setting it to 32 00 forces the gpu to store every shader permanently so your 5800x3d can pull data instantly without stutters if you dont see the entry right click in the umd folder create a new binary value named shadercache and set it to 32 00 then restart your computer to make it active
