I've got a 5870 with a 3 monitor setup running an i7-950 at 4.2 GHzThis is my first attempt to run FSX at this level and wondering what kind of performance I should expect from it. If flying at 3,000 feet approaching a heavily forested area, in the distance it would appear to be a small amount of trees, then within about 3 miles, trees pop up and it becomes quite dense. Similar thing with buildings in city. I'm getting what I would term as micro-stutters and more pronounced while turning. Can I do better with the 5870 and 3-24 inch monitors (1920x1200)?Seems to run best on DX9 with frame locked at 30 (if unlimited it stutters much more)ATI drivers 10.3O&O 12I followed Nick's tuning guide for everything relating to Vista for my Windows 7-64 systemI see he recently posted something for Windows 7 now and wondering if it's worth doing the install again.

No: certainly Nick's guide is a basis for the setup, but I think that implementing Bojote's pinned BP=0 post has a much, much greater affect on frames and "fluididty" - in fact for most of us that followed the post - it is the answer. No more micro-stutters. You are getting vSync issues when you're turning - an inherant problem with the current ATI cards.Regarding the three monitor setup - it all depends upon what and where you fly. Using the Maddog at Seattle I can lock at 24 frames with most things to the right at 3840 x 1024 - but only with AG pulled back 1/2 way, ai at 30% ga at 10, road at 12 (MTX5.2b): Rex #4 cloud cover. If I use a single 1900 x 1200 in the same place I can lock at 30. The Maddog is up there when it cames to being a frame hog. I found the Do27 worse. Anywhere with a "normal" aircraft (almost anything else!) one can easily run at 30fps, but without Bojote's fix everything has to be pulled back to achieve smoothness.The more pixels that have to be painted - the slower it gets, so I reckon 3 x 24" (5760) you will not be happy with that.

This is actually one of the (few) areas where the 5870 really shines in FSX. To my surprise I got pretty much identical FPS when using 3 24" monitors with the 5870 (eyefinity setup) as when using a single screen. I haven't had time to finetune it but I certainly don't have any performance problems or stutters or anything like that. My biggest issue right now is that the I'm not quite happy with the outside view. Either I zoom out and get detailed textures but a very stretched image at the edges, or I use a more sane zoom level and get really blury textures (because of the zoom level, not because the lod_radius value is too small). It seems that WideViewAspect wasn't really targeted at using 3 screens. It works well with a single widescreen or even two of them, but when using 3 it's a totally different story. I hope I'll find the time to investigate this further but any hints are appreciated.
