Getting very low FPS outside, VC fps are amazing but once I go outside fps drops like a rock. Not sure if the outside textures are the main reason, but I don't have this issue with any other aircraft's in my sim. I also have chaseplane as my camera.

It just seems really weird as I don't have this issue with any other payware aircraft's in my sim. Is there a way to reduce to 2k exterior textures?

Didn't have any issues! On my lower-mid grade PC it runs pretty well with mid-high settings, 150+ AI planes, and ORBX sceneries, all in VC and exterior.

+1, Frames rates fine inside the VC, apart from HSI that seems really stuttery. Go outside and frames plummet. Not using chaseplane.

Just to disprove this theory of chaseplane being the cause, Im pretty sure you can disable Chaseplane per aircraft, and reset the .cfg to before chase plane. Can almost guarantee it won't be chase plane

[quote author=Captain_Sim link=1588038720/9#9 date=1588092227]It's 4K Ultra-HD exterior textures. Some systems with limited video won't like them.
We'd make a light 2K textures set if we get enough requests. So pls drop a line if you'd like to try the 2K set.[/quote]

Yes I would like to try the 2k set. I am having very low FPS even with my RTX 2080 Super and i7 9700k.

I hope the lite 2k pack is more performance friendly. The 757 has this same performance issue. All my other planes run smooth with chaseplane.

Kind regards,
Thank you

I would like a 2K set too please!

yes please 2k textures!

Here we go: 2K textures set.
Unzip to ...\Prepar3D v4\SimObjects\Airplanes\CS_B767-300ER-II_PW4060\

That will save ~500Mb for your video.

If you want the original textures back - just reinstall (repair) the 767.

These textures haven't made a difference for me, still suffering with poor frames on the external model but fine in the VC apart from the HSI stutters.

After installing this, my taxi and landing lights are also no longer working. They're illuminating on the ground but not showing on the model.

Having the same issue as Jake. And to answer the question, VC gives me 30 fps roughly, exterior drops to 9 and below.

Just applied the stuff said in the linked HSI Stutters topic. Gonna fire up and see how it is then.

What do you get on default aircraft at the same conditions/location?
Screen shots of both (the 767 and default aircraft) pls.

Will double check with the default later, but the route i'm currently doing i've done a few times with Captainsim 757 Captain III and have not experinced any drops like the ones im experiencing with the 767.

I don't seem to have any issues with external FPS using ChasePlane.

external view comparison QW787 and CS767, the fps is a huge difference

bmanvi wrote on Apr 30^th, 2020 at 6:04pm:

Interesting.
Pls check if reset of P3D display setting to deafult makes any difference.

Please find attached my images.

Pics taken at P3D4V.5 default airport KVPS in default 2k CS Livery.

There is 13.1 difference in FPS between VC and External view, the external view providing fewer FPS than VC.

https://ibb.co/vdY8f2W CS 2K EXT Custom Display Settings
https://ibb.co/TbN0cc0 CS 2K VC Custom Display Settings
https://ibb.co/thVnSqB Custom Display Settings

The images below are from re-setting the display values to default.

https://ibb.co/nLC9vTv CS 2K VC Default Display Settings
https://ibb.co/51y22GM CS 2K EXT Default Display Settings
https://ibb.co/DtQKDtf Default Display Settings

Even though the default values appear more positive, you need to remember that not everybody flies into default airports with sub standard default scenery.

I'd like to re-itterate my previous post, stating that i had no such issue with your 757 Captain III using my referenced Custom Display Settings or other high-end aircraft addons.

My sim will not load this aircraft, default 2K livery or my own repaints with the default display settings.

Thanks,
Ok what we get:
- Just 2 users (you and bmanvi who is out for some reason). So there's no serious problems in the 767 that could affect mass user.
- The fact that the 767 exterior model does cause fps drop on your PC.

We believe the 767 exterior model complexity pushes some limits of your sim and/or PC setup. That Prepar3D.exe crash is an extra proof of that.

Possible solutions:
- System and all drivers update
- Performance check e.g. https://www.userbenchmark.com/Software
- P3D and/or windows reinstall.

Before that I'd try the 767 on another PC.

I am reporting back. FPS outside is really acting weird, now and then it is plumiting to below the 10fps. While when I then hop back into the VC and go back to exteriror, sometimes the FPS are normally in the exterior

(first a request to merge this post with the 2 earlier from this morning)

Second, I've found something odd. When I load in at an airport in the 767. And hop out, FPS are good! But, whenever I go back into the VC to switch to exterior view a few minutes later, the FPS have plummeted.

I'd like to add the following: And yes, it does run heavier on the frames compared to other payware add-on aircraft.

Captain Sim wrote on May 4^th, 2020 at 7:38pm:


Yes I understand that, I was just telling the folks here why they may experience some lower frames. Anyhow, so far I'm really loving the thing with all its glorious details.. keep up the good work. 

hmu with a 2k as well!

Captain Sim wrote on May 4^th, 2020 at 7:51pm:


+1 the exterior details are amazing with PBR. Very life like.

It's available long ago https://www.captainsim.org/forum/csf.pl?num=1588038720/16#16

The 767-II exterior is a next generation model with unprecedented level of details.
For those whose PC is unable to handle the exterior model, we'll make a light version with all bells and whistles removed.

Meanwhile you can try the 2K textures set.

Also installed 2K liveries, and p3d crashes when changing to external view, in VC 30-40fps

Would it be possible to get an updated pack? Since the metallic maps that come with the currect 2k texture pack are not correct for v5 users.

I'm still getting low fps outside but in VC i get good fps. I don't understand it even with the simplified exterior i get low fps. i get great fps with the 757 and 777 but when it comes 767 low fps even when i pick it for a preview it takes for ever to load up. if anyone could help with that it would be great i have yet to be able to do a flight with the 767.

So with this 2k texture set how does it exactly work? What happens if I download a livery from ACE that is 4k? That will obviously override the 2k textures correct? Do I specifically need to download liveries in the ACE that are 2k?

Captain Sim wrote on Jul 18^th, 2020 at 8:00am:




How would I do that? The option in ACE is grayed out to chose either 2k or 4k

Captain Sim wrote on Jul 20^th, 2020 at 9:32am:





I've been simming for 15+ years and not once have I ever had to manually edit a DDS file for a livery, nor do I even have a clue how to do that...I guess I'll just only download 2k liveries that are available in the ACE...

Captain Sim wrote on Sep 14^th, 2020 at 9:37am:


Well atleast you can alleviate our FPS troubles by allowing us to omit the Passenger Cabin. I don't see the point of having it anyways as it is eating my fps a lot. Has almost made the Sim become unusable.

Captain Sim wrote on Sep 21^st, 2020 at 9:23am:


That does'nt solve it for us, why would I disable essential features like the doors for passenger exits and the cargo doors just to access a cabin, instead you should develop an option where we can keep all the external model animations while omitting the passenger cabin. That's the least you can do considering you have charged this much.

Swapnil.

That's and option. If you don't like it, you need a better PC.
Also we have an older 767 for FSX which will run on a low-end PC just fine.

I am using a 2080ti and i7-9700k and barely managing 25fps in the vc. Far from a low end machine. Performance is slightly better in p3dv5, but negligible.

Hello.
I would like to know if there is a way to have the exterior animations (opening cargo door etc) using the simplified exterior.
