MW2 FPS DROP 4870x2

Hejsan!
Jag har länge försökt lösa detta problem! Men nu undrar jag om det är någon mer änn mig som har samma problem.

Jag har ca 80-125 fps i spelet men på vissa banor typ Terminal vid flygplanet så kan jag vrida mig åt ett hålll så får jag 35 istället!!
Det är så på vissa banor även om det inte är några spelare eller så på dem just då.
Jag kör Steam och jag har provat drawwater fixet, provat alla möjliga ccc versioner då jag tycker att nyaste funkar bäst.

Lägger in min config så ni ser inställningarna jag kör
