Well I'm excited. I am awaiting delivery of a major upgrade to my rig - a new OC'd i5-2500k with a dedicated Intel SSD for FSX and nVidia 570X is on its way. I can't wait to get going installing FSX and my add-ons and enjoying (hopefully) FSX near-nirvana.I am well on top of the install procedure for Windows 7, FSX, UTX, GEX, REX and UT2, and will be following received wisdom every step of the way just to make sure I don't screw anything up. Crikey, I've done it enough times now I reckon I could do it blindfolded... BUT I am also strangely anxious. A familiar spectre lurks at the back of my mind... installing the OPTIMAL video driver. I am frankly dreading going through every permutation under the sun of nVidia drivers, Inspector settings, and .cfg tweaks in the everquest for stability and quality. My understanding is that 266.58 is the earliest driver that is compatible with GTX 570. Would I be right in assuming it is also the most reliable? Should I risk installing any of the 27xx series drivers? All I want is to be able to fly demanding add-on aircraft in stutter-free flight with decent FSX graphics settings - and I am happy to sacrfice some IQ at the top end of the spectrum to achieve this. Any thoughts? Has anyone succesfully configured a similar spec to achieve fluid motion? If so, I would love to hear about your driver, Inspector and Bufferpool settings ...

I am running 275.33 and I am getting corruption unless I have UsePools=0With this, there is the occasional artifact, but seems stable and relatively stutter free.Before you install everything, you should run FSXMARK11 and test with that first. In fact, I use it to tune my final install as well, as it gives me a reproducible flight on autopilot to test with.
