tried with medium and high settings...off and on post effects...v-sync on an of...tried with AA and AF from ingame menu and from nhancer, nvidia panel...everything I tried...even upgraded my sound card...someone at neoqb suggested me to unplug my trackir from pc and to try....i had stutters and FPS under 30 even with trackir unplugged....nothing helped....and the strangest thing is that prior to patch 1006 ROF was running fast and smooth..no stutters, not even a smallest problem in performance range....strange
