Check the 'game_antialias' value in Your VCMP Config located at <C:\Users\PCNAME\AppData\Roaming\VCMP\04beta> I also had antialias vaule at 2 causing fps drop when I get near molotov, strip club and pole station smoke, rockets trail causing drop of fps. Change the value of antialias to 1 or 0 and check if it does something. Hope this helps.
