Plutonium

For 2 months pluto iw5 fps drops often when playing, this never happened before 2months ago. It happens after an pluto launcher update. I can't play game. But meanwhile teknomw3 client runs the game smoothly at high settings on the same laptop tha i am using to play pluto iw5(mw3). I tried everything but none of them helped. My guess is plutonium launcher causes the fps drop. Give me a solution if anyone have. I really want play on plutonium becuase it has more players playing on it.

When I play in Pluto iw5 a team deathmatch or any other category my mouse not responding properly like my character view not moving like move my mouse physically. It is lagging for some time and then working a little bit good and I had to increase the in-game mouse sensitivity to play a bit smoother.
