holy shit, theres almost exclusively idiotic, nonsense advice in here, don’t listen to any of this. people also didn’t really reply to your question. you switched your gpu to a much better one, you uninstalled drivers. now your tarkov performance is way worse. this is likely independent of cpu or ram. this is tarkov being fucky with you. unfortunately it’ll be unlikely you’ll find a solution here - i don’t know either. you’ve also given very little data about the 45fps. how constant? depending on AI/pmc count? no matter which direction you look? same in offline mode? every res? using gsync or anything? troubleshoot every setting and i’m sure you’ll figure it out. tarkov settings also like to conflict with gpu driver settings. your ram sucks tho, ngl. gl!
