Hello, been playing Rift for a while now with good performance. But lately ive experiencing some FPS drops in Sanctum and other areas with many players and fog etc, so i was thinking if there are a way of going into the Rift folder and Delete some kind of WTF/Cache like folder like in World of warcraft and such, tried searching the folder but couldnt find anything i would like to delete in fear of clicking away something important. Any suggestions?

(Theres probably a thread that already explains it but i cant find it so if there is you can just write the name of the post here) Thanks
