Just leave out fiber frame it useless in multicore after sp2 update. Very conservative in settings and found that have less problems when I tweak less. Water low 2x and terrian 15, AI 15 and cars 10, and use less complex planes help thou. Rarely, get blurries unless I overreach the settings.

I can't maintain 30 FPS in every situation like on short final into Fly Tampa's KMDW in my PMDG NGX. My hardware specs are posted and I followed Word Not Allowed's guide to the letter. You should be able to maintain close to 20 though. Did you disable the turbo mode function in BIOS prior to overclocking??
