Hi,
last time I tested this settings from Avsim Forum (idea mod).
http://forum.avsim.net/topic/369500-...hness-in-fs9x/

I dont like internal limiter (fps falls a lot as we know!), just I used external limiter only till now (for ATI video cards - RadeonPro: http://www.radeonpro.info/ ).
I checked this advices from Avsim for nVidia - with VSync and 50% of FPS (so 60 VSync and 30FPS on internal limiter in my system) but for Radeon - and "eureka"! Stable 29,5 fps on each scenery (very complex too) addon with smoothing on GPU 8x16 (before I have 25-50, so nice but as always, fps are crazy, not very stable). No any stutters, stable FPS. Looks like very nice find!

For sure I setup too:
FIBER_FRAME_TIME_FRACTION=0.1 and I take calculation from this topic: http://www.simforums.com/forums/fsx-...opic37948.html :

MAX_TEXTURE_DATA=800
TEXTURE_BANDWIDTH_MULT=78
TEXTURE_MAX_LOAD=1024
UPPER_FRAMERATE_LIMIT=30

With default textures (FTX Global) works very well but for FTX other scenery (like f.ex. England ect.) I noticed some of kind blurry and slow loading textures.
I know this parametr - FIBER_FRAME_TIME_FRACTION=0.1,it generates max of fps at the expense of fast loading textures (better to use FFTF=0,99 for this but it isnt works well with internal fps limiter and VSynch = bigger stuttering).

Any idea how to force FSX faster loading textures and no blurries in this mod idea?

Btw.
If You dont know this idea mod - try it - Im very surprised, maybe I have less fps but very stable and with high level of smoothness on complex scenery too. Just this blurries.... : / ...
