Slew Mode and Blurry Terrain

Featured Replies

I'm just wondering if anyone else has noticed this. I don't think it's a bug, since it probably results from FSX not being able to read the scenery files off the hard drive fast enough. It seems like it takes FSX a while to catch up to the rapid plane movement when you slew. It almost looks like in Star Trek when the Enterprise went to warp speed. During that period, the terrain is understandably blurry, but unfortunately, this continues on my PC for about probably 20 to 30 seconds after coming out of slew mode, which is somewhat annoying. Are there any graphics settings that help reduce this lag? I'm running at 1600 X 1200, at mostly high graphics settings, with an nVidia 7950 GX2 with an AMD FX-60 and 2 GB RAM and my frame rates are generally in the 25-35 FPS range.

This is a well-known effect. In a previous version (it might have been FS2002) this was a massive problem and was known as 'dynamic blurred textures'.Fortunately FSX has a very useful trick up its sleeve that gives you control over this. Open fsx.cfg in Wordpad and locate the (Main) section. In this section add the line FIBER_FRAME_TIME_FRACTION=0.33This setting determines what priority is given to updating textures. Increasing the value makes the textures update faster. 0.33 is the default value. Try larger values, e.g. 0.4 But be aware that a faster texture update will reduce frame rates slightly. Try different values to find something that works for you.As a matter of interest I use a value lower than the default (0.2) Texture updates are still acceptable but it gives a small but useful frame rate increase.Best regards, Chris

If you slew, chances are you will see blurries, and blurries always persist about 20-30 seconds after you've stopped. It takes that long for the display render to "catch up" with you.There's only so much you can do about it. A faster machine will reduce the lag time. FIBER_FRAME might help as cwright said, but not much when slewing. FIBER_FRAME works more for normal flying. But slewing at 8000 kts is going to cause blurries on any machine.RhettAMD 3700+ (@2530 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 3-3-3-8, WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian

Slewing will cause blurries no matter what.The best thing to do is to assign a key as 'Refresh Scenery'I use 'Tab' and simply press it anytime I have needed to slew anywhere. The scenery simply reloads and all is sharp again.Glenn
