P3Dv4 Settings for flying fast fighter jets

[simmerhead]

I've been trying to get P3Dv4 to work without blurries and texture popping when flying fast jets, but am unable. Does anyone have any good tips? 

I've flown with zero auotgen, no traffic, no shadows, no water effects etc. But still, texture loading just can't keep up when flying 700 kts in a jet at low level.

LOD setting one , perhaps , 2 notches to the right and a lower framerate ...

I have not found anything that improves photo scenery blurries, but this helped me with delays in loading autogen:

In the Prepar3d.cfg [DISPLAY] section, added

TextureMaxLoad=30

TEXTURE_BANDWIDTH_MULT=180

Might help. There's been lots of discussion on these tweaks here if you haven't already read about or tried them.

Add

DCS=1 to config

Texture resolution to 1m for starters.  And then basically find a balance for CPU related features (like AG load distance and AG settings).  I've found if you just cut sliders the CPU won't work hard enough.  Try doing the above plus AG at mid range.  Make sure DL, and reflections are set to off and low, respectively

Try the tweaks the guys above suggest, but at 700 Knots (supersonic) I seriously doubt you will get scenery to load in time for you to see it clearly? That's my point really, at that speed and low, you really wouldn't be focussing on "scenery" anyway! The HUD would be your focus and then a glance at the HSI. 

In my recent love affair with the VRS Superbug at low level, I have scenery maxed out to load as much as the sim can, before my jet gets to it, but remove autogen completely. The houses would be a blur anyway, even if they were to scale lol! The worst area is Orbx North Germany, it's so full of different types of scenery (Brilliant Orbx!) loading that at speed is a problem.

Gordon mentioned DCS. He has a point there. Their NTTR map is like the planet Mars, in that there is not much there to render, save desert! Hence we can get smooth flight at 100 fps at 500 knots at 50 feet!

Nip over to Normandy with some smoke around and even at 100 knots you will be hard pressed to not see some stutters!

Best regards.

Ha ha... Good one! If DCS had complex scenery of my home air base I'd use it more, but I'm married to P3D for now.

Thanks. My problem is that I fly in Norway and the textures in complex mountain scenery is painfully slow to load.

This is the kind of flying one should be able to do in a flight sim developed by the worlds largest manufacturer of fighter jets...

Ryan's advice is really spot on. Besides trying to keep your CPU from being hammered, smaller textures (in all ways you can get them) will mean that the GPU will also not get saturated.

Sorry , I meant to the left.

[ryanbatc]

I would also unlock frame rate - if that wasn't obvious.  May introduce a few stutters but 700 kts lol!  That's fast hehe

Unlocking helps with framerate but it will introducé extra blurries If you are already suffering from it..

[ryanbatc]

True but I think making crisp scenery at 700 kts isn't possible with high fps.  So for me higher fps (unlimited) would be better than a few blurries.

I would think if a person went the fps locking route they'd need to lock at 30 fps, no higher.

@simmerhead

Have you tried any of the suggestions?  I'm curious if it's helping.  I usually only fly GA so if I'm going fast (Realair Legacy fast say 250 ktas at 4000 ft), usually that's the fastest I can fly on my aging 2500K system.  If I'm in Orbx regions with their payware airports I'm having to fly slower to get everything to load.  If I fly something like the Iris PC21 or T6 II I'm aware (and ok with) the fact that my system won't keep up.

don't know about going supersonic down low but m0.7-0.8 is doable with decent scenery detail over orbx pnw.
