As the title says whenever i load into a game of six siege l lag, so i opened up task manager and noticed whenever this lag appeared 100% of my disk was being used up. however once i have loaded into the game it runs just fine and with 70+fps consistently.This has only started happening recently and would love to know what i could do to fix it.
Meany thanks Andrew.
