I play with HBAO off and all settings on low with DX9. Will be using DX10 when I build my new rig and finally upgrade to Win 7 for DX10/11 though. Again, from my first post FPS is acceptable for me right now (~45-100, average about 65) and I don't really care about eye candy, the problem is physics and FPS dips in large servers. For instance, nearby wall starts collapsing from a tank shell, FPS dips to under 40 and it's hard to aim. Also noticing a lot of FPS dips with sighted weapons and shaking from explosions that make it difficult to aim. Ever since BF1942 introduced vehicles and large multiplayer server it seems to be a rule of thumb that you always want as much raw CPU as possible to avoid huge FPS dips from physics. I am kinda curious what sort of FPS people with high end rigs (i7, 5850+) get on 32 player servers.
