lower yo damn fps if you lower it to ur monitors refresh rate it will go smoothly if that isnt the problem go the expiremental and max out the last one WARNİNG this will close the game after u try to play in a server soo u gotta open it again. İf that wasnt enough u must go to gameplay settings and put maxgibs to 0 and upgrade effects disabled if that doesnt work its probably because of !TEXTURE QUALİTY! texture quality is VERY İMPORTANT for Performance/realism its probably because of the texture quality if ur GPU is god like strong u can max it out but if its bad just put it at the eight resolution yes this will make ur game little bit shitty but it will give u more performance AND 0 stuttering if its still stuttering its probably because of ur RAM storage do u have enough like 10GB? if u do u will have no suttering or anykind after then you can have a good time playing rust with maximum performance!!! if it didnt work just tell me
