Hi! I've installed the modification to Dx9 but unfortunatelly i think my peformance got even worse!I followed the basic steps like setting threads ( i use a 9900k so i set it to 16) and put the flag "1" on the save shaders option. Not sure what to try next, any help is appreciated! Edit: I rerun GW2 and i noticed that my settings didnt save when i edited the config (from within the game's overlay window).
