Flight1 GTN 750 performance impact

Recommended Posts

Hi,

My Specs are i7 7700k / 16GB 3200 Ram / GTX 1080

 

Question 1

Can anyone comment on the performance impact of the flight1 GTN 750?

I am flying AntsAirplane's Eaglet to use with the GTN 750.

Currently I am capable of flying the Carenado DA42 glass cockpit smoothly...if that's any type of reference point.

Also

I see that we can't load P3D flight plans into the GTN 750. How does Active Sky P4 know what weather to load if a P3D flight plan is not loaded?

I don't really see any hit with the gtn units

Regarding flight plan, just load your flight plan into active sky and then enter the flight plan manually into the GTN unit.

Hi,

My (freeware) SimLauncherX application can export FSX/P3D flight plans in Garmin .gfp format to be used by the GTN units.

No noticeable performance hit.  I have a similar setup as you, only difference is I have a gtx1070.

Me neither. What I get is the GTN slowing to a crawl when it is undocked. When docked, it is nice and smooth.

Really? You're trying hard to get me to try SimLauncherX. (getting close too)

I've documented this in other areas but the GTN 750 will use 5-10% of your CPU so if you have it set to one core that could use 40% of that core just for the GTN if you open 2 GTNs in your panel it doubles. I tend to run my GTN 750 or 650 on the last 2 core option this way it stays off the first core and allows two cores to spread the load. By the way things like ChasePlane also use 4-6% of total CPU so these things add up. I tend to move all addons to the second core that are small users and larger uses like GTN and CPto either the last two cores. The GTN configuration tool has this option. I use Simstarter NG to launch all my addons and assign cores to keep everything off the first core (core 0) to allow it for P3D which even in v4 bangs that core 100%.

Bottome line GTN 750 uses the most CPU of any addons I run and you should watch core loading with the task manager to balance things. Oh by the way I network Active Sky weather in from a client PC, if you don't do that cores will fill up quickly with medium to high settings.

Agree ,

Tried with GTN.INI Core =998 (which puts the GTN1 (750) on core 3+4 and GTN 2 (650) on core 0+1 (?) (I7-4770K HT OFF)

Doing so increased the load on those cores making my before stable OC crash at FTX Germany Berlin:biggrin:. Its summertime and outside temp is having an influence as well.

Maybe spreading them over 3 cores is better. 

Is there a way without Simstarter (dont have it) to set the CPU Cores for Chaseplane,Active Sky Network,Vpilot etc automatically ?

Noticed that Chaseplane was struggling to change views sometimes on 2 cores (1+2)

 

Thanks

You can do it manually with task manager>details>affinity assignment but it needs to be done every time you start up because it doesn't hold. Another popular choice is Process Lasso

Also remember to keep things off the first core which is core zero that gets consumed by P3D

At present there is a bug with the GTN Cmplete and for some users it can't import gfp files (certainly in P3D V4).

It's being followed up in support forum.

You can call up an AM through FSuipc4 , ( not tried it in FSuipc5 )

this is the command line for AS16 in p3dv3.4

[Programs]
Run1=AM=12,CLOSE,C:\Program Files (x86)\HiFi\AS16_P3D\AS16.exe

Where can I find the function to export a Garmin .gfp Flightplan ? I can not find anything about it in the SimLaucherX-Manual.

Thanks, Achim

PS: Found in the Flightplan Menu

Hi Achim,

The manual still needs to be updated. You can look through the change log ('Change log' button on the Home ribbon tab) for the latest features,

To export a flight plan, just select a flight plan and select 'Export to .gfp' on the 'Flight plan' ribbon tab (last button in the Route group).

One is fine but 2 seems to have a GPU impact.  If not there is a botlekneck somewhere.

With either the GTN750 or 650 in an aircraft I see no noticeable performance hit.

However, I accidentally set my A2A C172 up to have both a 750 and 650 and the performance hit when using both was significant.  This surprised me somewhat but didn't bother me at all as I really would only want one unit in an aircraft (especially a C172!).

Hi Michael-

Where did you get the "Core=998" info? I'm now running HT and would like to know other combinations as well.

Thanks,

Mark

What does loading a flight plan into the GTN have to do with AS4? AS4 loads weather into the sim relevant to your aircraft position, period. You can load a P3D flight plan into AS4, but it's only value is to show flight plan data, a brief of the route weather, and the flight plan on the AS4 map.

As far as loading flight plans into the GTN, try SimBrief https://www.simbrief.com/home/index.php

SimBrief can output plan files for P3D (which can also be loaded into AS4), the GTN's, as well as formats for most addons available for P3D. It's free to use, highly capable, and really convenient.

Kind Regards,

Michael,

Try Process Lasso. It's available free, with some limitations, but if all you want to do is set affinity, that's included for free. Nice thing is that the setting is persistent, so no need to set it every time you run those apps.

Perhaps a different issue - maybe the half framerate problem that pops up occasionally with undocked panels?

I use a planner that outputs several types of plan for the GTNs. A custom user waypoints table is also generated in different ways for waypoints that don't exist in the GTN navdata. Works on P3D v4. I'm not sure if that's available from other planners but have not checked lately.

Hi Mark, The selection for choosing the 'cores' in the  'FLTGTN ConfigP3d tool are ..Auto..0..1..2..3..4..5..6..7..Last two..&..All.

After selection you can look at the F1GTN.ini file in the Airplane folder.

ie

[GTN750.1]
Airplane=1
TAWS Voice=1
AVDB=0
Unit Type=1
Radios=0
Autopilot=1
Mouse=1
Link CRS=1
Auto CRS=1
Fuel=1
Sound=1
Invert Mouse Wheel=0
Active Mouse=1
CPU Core=1.................................note core 0 was selected in the config tool.  If last two selected this value will be 998 and for the 'all' selection this will be 999
Play Click=1
VC Brightness=5
Color Airplane=0
VFR Code=1200
Fuel Type=0
[GTN650.1]
Airplane=0
TAWS Voice=0
AVDB=0
Unit Type=2
Radios=1
Autopilot=1
Mouse=1
Link CRS=1
Auto CRS=1
Fuel=1
Sound=0
Invert Mouse Wheel=0
Active Mouse=1
CPU Core=6 .................................core 5 was selected in the config tool. If last two selected this value will be 998 and for the 'all' selection this will be 999
Play Click=1
Play Click=1
VC Brightness=6
Color Airplane=0
VFR Code=1200
Fuel Type=0

 

When I select 'Auto' it appears to show the core values of CPU Core =0 for both the 750 and 650 respective and looking at the AM values in task manager ( w7 here) it shows the 750 on core 7 and the 650 on core 6.. a bit odd.

this is for the Milviz c310R

I found when using Prepar3d v4.1 I was having some sluggish issues so I used the 'ALL' selection. but ver 4.2 appears to be a lot better. this could be for the update to 2.05

hope this helps

Hey Bob-

After much ado, I pieced much of this together over a bit of time. 

Oddly enough, Core=0 in the .ini file results in core 7 checked in the task manager, on my machine anyway.

So, I put together an AM (117) which leaves core 7 open.

Seems to work pretty well. So, I kinda did this backwards :>)

Thanks,

Mark

I would say that even with poorly selected AM there would not show a significant performance drop.

You need a .PLN for P3D and you need a .gfp corresponding to the plan to load into the GTN.

Problem with converting plans for the GTN is that if your navdata is different to the current data in the GTN then some components of the plan might be ignored if they don't exist in the GTN and if they do exist in the GTN then the GTN Lat/Lon is used which might be different to your plan.

To get round this I use a planner that outputs all waypoints as user data and the plan is exactly the plan you are using. If the ICAO exists in the GTN I see the info even though it is sent as User data.

Hi Steve-

What's the name of that planner, if you don't mind me asking?
