Hi,

I recently bought the Aerosoft Do27 package for FSX and am very disappointed with the FPS I am getting from it ? I know this is a universal problem after scouring the WWW but do any of you have a 'fix' ?

Is there a way of reducing the texture sizes? Or a tweak i'm not aware of?

Cheers,

Mick

The Aerosoft Do27 package is a very advanced addon with some amazing features, am afraid there is not a lot you can do without compromising the experience too much if you dont have the pc system to run it adequately...

You can reduce the texture size by adjusting the global texture size in the FSX Graphics menu and reducing the global settings in the aircraft menu....Things like reducing un ticking the High resolution cockpit option may help...
You do of course realize this will reduce your overall pleasure of this fantastic addon.......

Of course many features on this addon require a heafty cpu to work correctly...not just graphics textures.........Besides the extraordinary visual model this add-on is equipped with features that have never seen before in FS. Over 5000 lines of code have been written only for the animations!







BIG FEATURE LIST:

Exterior Model:

* All standard animations like control surfaces, cowl flap, elevator trim, wheels etc.
* Control surfaces can be fixed.
* Control surfaces are affected by wind if pilot left aircraft and controls have not fixed.
* Elevator vibrates during engine start and at low rpm on ground.
* All doors can be handled separately (that means lock/unlock, open/close and dumping)
* The 2 engine doors can be opened separately as well as the whole lower cowling.
* Detailed Lycoming GO-480 B1A6 engine.
* New propeller animation for slow revolutions during engine startup.
* Propeller can be damaged by ground contact.
* Exterior equipment like brake chocks, warning cones, camping equipment, tools, information panel for flight days etc.

Virtual Cockpit and systems:

* Different panel layouts.
* Additionally defined FSX cameras
* Panels and instruments may be damaged by hard landings.
* All automatic circuit breakers and circuit breakers work.
* Instruments may be inaccurate, needles may be influenced by vibrations, g-forces or disorders.
* Attitude indicator and compass card are driven electrically and have to be aligned / calibrated. The compass card will start to rotate for several minutes if electricity has been cut.
* The glass of the vertical speed indicator may be broken.
* Junghans chronograph with windup mechanism and timer.
* Avionics may be damaged if avionics master switch is not turned off during engine start and engine shut down.
* Engine must be primed.
* Engine prime can lead to have too much fuel in the starter system. Removing superfluous fuel is possible due original procedure or mechanician.
* Engine starter can get overheated and damaged.
* Cowl Flap produces drag according to its setting.
* Engine cooling is influenced by angle of attack and propeller revolutions.
* Engine fires can occur.
* Fire extinguisher can get exhausted.
* Oil leaks can occur.
* Realistic oil consumption.
* Engine treatment influences oil consumption.
* Engine and gear can get damaged by:
o High RPM
o Low RPM
o Fast RPM changes
o Low Manifold pressure
o Long engine starts
o Low oil level
o Fires
o High temperatures
o Low RPM during descent
o Negative Propeller Thrust
* If Engine gets worn it looses power.
* Propeller can get damaged
* Warm weather can cause air bubbles in the fuel system, making the engine stutter. The fuel pump solves this problem.
* Cold engine can go out.
* Real engine start up procedure, with starter circuit breaker, priming and mixture lever in cut off position.
* If engine is not serviced periodically, engine start will get more and more difficult.
* Fast changes on engine settings lead to damages.
* Propeller pitch can't be changed when engine is shut off.
* Oil temperature influences operability of propeller pitch.
* Mixture can be adjusted manually. But this is not recommended. When the lever is all way forward, the mixture is set automatically.
* Generator only works at 1300 RPM and above. Generator relay is audible.
* Fuel quantity indicators are not very precise.
* Pitot heat can get damaged if enabled on ground.
* Structure and controls can get damaged through high speeds and extreme manoeuvres.
* Flaps can get damaged through high speeds or when being lowered as long as the cabin doors are open.
* Windows get dirty.
* Each door can be locked/unlocked, opened/closed and dumped separate. The latch for the left cabin door can be disabled, so the door will stay open during flight due air stream, and can be closed by shortly lowering the flaps. (Real life procedure after the skydivers left the plane)
* Windows of the front doors can be opened.
* Ventilation controls are functional.
* If you forgot to remove the pitot cover before flight, airspeed indicator will not work, and the cover can only be removed on ground.
* Vibration effects through engine, ground roll, stalls etc.

Unfortunately you cant expect to run a simulation of this nature on a lower spec pc, its a pain i know, my system isnt perfect either!, but as addons get more sophisticated our systems have to as well...


What spec system do you have Mick?

IMO...The biggest problem with the Do in FSX is that it is not, and was not reworked into, a true FSX model when released for FSX, and it suffers from it.

A great aircraft that I used to fly it often in FS9, but rarely think about it in FSX.

Look for a small program called 'model checker', and it will show you which of your aircraft are true FSX models, and which are still FS9 models. All of my true FSX models outperform the FS9 models...some by quite a bit.

Unfortunately most addon company did not rework their model to be fully fsx compliant (even though compatible and sometimes labeled as fsx certified), such as all the wilco products. Very low frame rate results. However, the aerosoft TwinOtter, for example, is a true fsx model and thus even though it is quite complex with 3D gauges etc, it still delivers good fps on med spec machine.

As is the Beaver, Eaglesoft Liberty, Columbia, and Twin Comanche, all RealAir FSX offerings, Carenado's Mooney, Dreamfleet's Dakota....etc.

DA's Cheyenne is a true FSX model, but it has so many other issues, I've put it in the hanger.

Some I fly anyway...the Carenado Cessna 182Q and RG (Jut finished a flight with the RG), MAAM DC-3....I can get adequate frame rates from these aircraft, but they do suffer a bit, but none were advertised as 'FSX' aircraft. In fact, just the opposite.

Thanks guys - wish they'd made this known when I purchased it, I would have left well alone!

They do do a reduced texture set for one of the models (E-EIBE I think?) I'll see if loading that makes a difference?

Very good point ''bkeske'' ........shame on all the payware companies for all the converted payware fs9 models out there masquerading as your FSX addons!

Still I get much better frames with the Do-27 than i do with say the very basic payware ''VLJ Business jet for FSX'' and considering the much higher complexity of the do-27 i think thats at least 1 of its good points....some fs9 models definitely seem to perform worse in FSX than others,and some like the carenado (FSX updated fs9 models) range seem fine considering their hi detail textures and cockpits......


I seem to be getting quite GOOD frame rates for the do-27 with my mid-range setup (intel duel core 3.2ghz and 2meg ram with basic 320meg Nvidia 8800 gts graphics card ), but i agree for people on the margin or with an older pc a true FSX might have made all the difference.

I think it is only fair and LEGAL if the payware developers out there at least made true FSX models for FSX instead of STILL palming customers off with FS9stuff...:( After all they soon moan about piracy and illegal downloading of their products.........I suppose their only saving grace is some companies allow refunds if not satisfied.........

Just remember, this aircraft is a Digital Aviation aircraft, not a direct Aerosoft product. Aerosoft simply markets it. Aerosoft's (their designs) FSX models (the ones I have) are true FSX models, as I stated above.

I've tried using the 'reduced texture' sets, but it has not made a big difference.

Shame! Such a nice model too - but 10 FPS dont make for a good experience.

The BeaverX returns about 25-30 !!

Just loaded the LOW textures - seems to have worked a treat, 15-20 FPS and no stutters!
