GTA V Epic Games

I need some help with gta v on epic games on linux. I installed epic games launcherfro lutris, installed gta v, and it runs, but I dunno why ,It didnt use the dedicated graphics, it only used the intel hd graphics 5500 , instead of my AMD Hainan, or AMD Radeon R5 M330 graphics. Steam games work fine, but not this. I even enabled the ‘Use Dedicated Graphics’ option in lutris settings which basically enables DRI_PRIME=1 ,but still nothing changed. Pls help
My PC specs - CPU - Intel i3 5005U , GPU - AMD Radeon R5 M330 2 GB , Ram - 8 GB , OS - Pop!_OS 20.04 (based on Ubuntu 20.04)
