MipMap LOD bias and performance

[ITSTHINKING]

I recently have been using RivaTuner to set my Mipmap LOD bias to -1.5 to make textures look better. I use high quality setting in my drivers and was wondering if setting the mipmap bias is costly to my performance or if it's worth it? I haven't seen any noticable differnce in performance in farcry but thats without hdr. What do you guys think?

nevermind

Well I played oblivion for a few hours last night, didn't notice any drop in performance at all. In fact the imperial city was running faster it seemed. Texture's really look a whole lot sharper from this.

but it shimmers.. just leave it to 0, if you want to make texture truely better with out shimmering you need hq af from ati

You still get the odd shimmer with HQAF. It's just much less frequent/noticeable in comparison to angle-dependant AF.
