Well tryied out with lower resolution of the textures and it helped a little and probably there is no freezes anymore but still when entering into last corner (here i have 23-28fps) of westhill international (in the middle of the turn i've got 60fps) then exiting from last corner with a view at the main straight (20-25fps)(then in the main straight fps goes back to normal 40fps) and somewhere in first turn still im noticing those fps drops at around 18-25fps. At any other track with or without high res textures i had stable 30-40fps on my rig. Just in those 3 places of the track it drops to 25 or even to 18fps, and as i sayed anything other than those 3 places to me seems to be 30-40fps and more (sometimes even 80fps).
