i tested zandvoort's latest gp track version i remember 2.54 i used porsche cup cars studio 397 20 cars in different weather conditions at different times of the day fps dropped to 43 fps whenever pit area buildings were visible for example in version 1.07 at the same points there was fps over 70 fps in the graphics there is not much difference would explain such a large fps drop in version 1.07 there are even 3d grasses compared to Nordschleife.lemans and Monza tracks in similar conditions run at over 60 fps although the dropper shows the cars in ten tracks it doesn't matter the fps speed these readings were in the rain and at night, in dry weather a little more during the day i.e. there would be a need for optimization in the pit area graphics cpu i5 4.5 ghz gpu 1080 ti 24 gt ram ssd 500 gt
