There has been some debate on whether the "slider lock" really helps out in FS9. In FS2k2, the slider lock would help maintain the texture quality of the scenery. If the slider was set too high, the sim would use lower resolution textures which would help cause the "blurries" close to the plane.Since flying FS9, I never noticed that, so I ran with sliders unlimited. In fact, many on this forum and flightsim.com would in fact claim that it was almost "wrong" to reign in todays hot video cards.Well, I think I discovered why a slider lock is a good idea.While flying with unlimited frame rates, I would often look out the side and notice sections of scenery that had not been rendered, Brown (or purple at night) with autogen sitting on them, or if I was looking at a plane parked next to me, it might not have any textures on it.Looking away and relooking would often reload the textures. However during a long flight it was often disconcerting to see a 100 square mile of scenery "missing".While playing around I set my counter to 24FPS, (based on motion picture film spped). Immediately I noticed the sim fetching the textures better. The fill rate during side views had gone up significantly, and I never had to "look away, then look again" to reload a texture.Just an observation, but if some of you are running your FPS lock at unlimited, and notice excessive missing texture renders on changing views, you may want to set the lock near your normal FPS count and that should limit missing texture loads.Just a thought.

I totally agree Will, While others might not. I have tried both ways many times and get much better performance with it locked, usually at 25. I actually notice more of a difference than I did in FS2002.Regards, MichaelKDFWhttp://mysite.verizon.net/res052cd/mybannercva1.jpgCalVirAir International VAwww.calvirair.comCougar Mountain Helicopters & Aviationwww.cgrmtnhelos.com

Yes I agree with you there I lock mine at 20fps if i get any stuttering it because im downloading files in the background..
