This is interesting. I tried 93.71 over 1 month ago and got a 10FPS+ drop compared to 91.47 and went back to 91.47 because of this. Perhaps this might be the reason that threading was not optimized. But it also indicates that optimizing with 93.71 may not be much of an improvement over 91.47 as is?. This will need to be tested.Re WOZ

I just checked my 93.71 installation for a 7950GT. That setting is not present for me in the Advanced Settings list, so apparently it is only available for certain cards.By the way - I know this whole framerate thing is a never-ending debate and search for the Holy Grail of settings combination. I have spent considerable time on it myself, and have come to some conclusions based on my tweaking and also what I've read here:1. FS-X is processor bound. No matter what we do to our systems, what we really need is a 10gHz processor (or better).2. Autogen and AI traffic are the real killers. I have both turned off and was getting some fairly amazing framerates just a few minutes ago in a multiplayer session. Sure I'd like to have both of those features "on" but the smoothness hit is just not acceptable for me.3. I've said this before, but the most success I've had in tweakage is starting with EVERYTHING turned off or to the minimums, and then sloooowly turning options back on or "up". I saved config files off at various points and descriptively named them. When doing multiplayer I use a very toned down config, since MP itself sucks away CPU cycles.4. Having real wx turned on can introduce an enormous variable into the performance equation - on a cloudy/stormy day my framerates still get hammered.I have "made myself content", mostly, with FS-X by internalizing the fact that this new version has gobs of stuff heaped onto what was FS9, and I shall just have to have stuff cranked down even further than I did with the previous version. The new features, especially multiplayer (extra-especially Shared Cockpit!) are worth it to me, and I shall just hope that AMD (or maybe Intel) pulls some kind of performance rabbit out of their hats in a couple years that will let me turn autogen and traffic back on 8^) .Dave Blevins>This is interesting.

I really don't know what happened or how I achieved my ~20fps, but I have to say that the results are simply nothing but amazing. I re-installed FSX again, did NOT apply any tweaks except the FIBER_FRAMES to 0.2. I currently have autogen set to normal (default autogen, not renamed or tweaked) and scenery complexity to dense. The rest is all set up "Medium High". Traffic is set to 40% with MyTrafficX and all other traffic is set to 40% as well. The "threaded optimization" did nothing but wonders for me.I just did another short flight and, wow, I never had so much fun (using TrackIR here as well). 20fps doesn't seem much, but it was enough for me to enjoy the flight. It just dips marginally about 5fps while in densly populated areas, but, boy, if you have seen the visuals then you really don't want to go back.
