I don't rely on special settings; instead, I ensure that I have the latest Mesa driver installed for my 7900XTX. Additionally, I optimize my gaming experience by using a set of launch settings that work well for most of my games, with minor adjustments made to the RADV_PERFTEST environment variable. These are the launch settings I use :

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json AMD_VULKAN_ICD=RADV RADV_PERFTEST=sam,rt,gpl,nggc,aco gamemoderun %command%
