hi, until now I never had problems with rF2. I always had 60-61 frames (vsync, video), all on full. With the new brake fog I have problems. Vehicles in front of me if I did cause the fog, my frames drop to about 5, when I drive through. This causes a Lag And turn off or screw down he can also not be. Situations in multi. But look great doing it! And on my system it is not. Build 342 i 3770 @ 4Ghz Palit GTX 680 4 GB etc greeting Mike
We have a new particle system with better looking smoke. But it currently might slow some people down and it sounds like you are one of those. You should turn down the setting and retry with each build and see if we have improved it's function on your system.
