Lag and low fps after update?

Hello, before the update, I was playing on certain settings and the fps were not less than 60-65 in BAE Combat, and I was running the game, streaming, and Discord, but after the update, I cancelled all the add-ons that did not work on the update and I tried to play with reduced dps and became 35, and there is a comment in the game. I tried to run the game alone and the same thing ( same setting ) and not open stream or discord ( i ask some ppl they say they got - fps abot more 25-30 fps mean who was play @ 60 fps now he cant play ??? ( agien i removed all addons witch is out of date befor i try 20 time ) maybe after they add new setting advanced options + Colors ??? its happned
