So Basically when i join a game of swbf2 the 2017 version it stutters a lot when i have been in the game for a while its fine this all happened after the most recent windows update i did the update on the 28th of January 2018 i think this is an issue with my Graphics Card i had this problem before about 1 month ago when it was doing the same thing about 1 month ago when i had the problems first i had upgraded to a RX 580 the card i had issues with and i have issues with now it was fine running swbf2 at MAX settings about 100fps after i fixed it until i did the windows update which i think did something now i had after doing the windows update encountered these problems from above i had an AMD driver update In Radeon settings so i did that thinking it may solve the issues it didn't. it changed nothing and i also have done all my updates from windows update last time to fix this issue i found out that since i had a Sapphire Nitro+ Rx 580 that it had a power and a Stealth mode so i switched that card to Stealth mode reducing the clock from 1450 of the power to 1411 in stealth mode some of my specs are if you need anymore info please feel free to ask Thanks.
