investigating Low FPS

[dggoofy]

Well, same issue. Poor performance. But it's a early access, first version. Let give ED time to fix it.

I've followed your lead and reducing textures to half gives a huge improvement... Of course one would need to fly it and test the feeling for a proper amount of time, but so far it does feels and sees quite ok

How do you reduce the textures?

 

[LuseKofte]

I have huge problems in Afghanistan. At least some parts of it, some said it was related to a lot of things, among them weather. Yes Chinook fly crap in some bases there.

Could You please tell me how You reduced the textures ?

With my reduction methos, there are quite some artifacts.

Solution for me until further is to set "Textures=Medium" (Not Terrain textures !!), seems to cut down VRAM usage quite alot with only minor Cockpit texture quality loss.

Thanks for reporting back. Going to try this first then, never knew this was even a thing.

Remebered to do this after flying around....just about to go back on and try!

THanks for the reminder....should do this after every update and every NVIDIA update to.

I don't know what your hardware is or if your running quadviews.

But for me the FPS is really good and i love the amount of detail.

Also have 0 problems loading in compared to other modules, i had loading in problems a month ago for a long period and couldn't figure out what was going on.

I decided since i had the install for years and it kept updating each time with new versions without ever doing a fresh install to do a fresh install.

Loading in problems gone for me and game loads fast.

i9 10900K, 64GB RAM, RTX 4080 OC, Meta Quest 3 @72Hz (ASW auto)

Similar problems here. Loading the Afghan Cold and Dark IA mission, OXR toolkit shows VRAM jumping to 105% and subsequent FPS drop to low single figures from which it doesn't recover. Haven't even tried a hot start mission yet. Don't see the point at this stage.

I've noticed the Chinook textures to take far longer to load in than any other module, including the Apache!!

No problems with any other modules I'm currently flying (Tomcat, Kiowa, Apache, Phantom). All performing as expected after the update. Even the Apache & F4, which I find to be FPS heavy hitters.

Cleared out all the usual folders after the update - FXO/Metashaders2

Not tried it in flat screen, as I'm pretty much exclusivley VR these days.

I'm concious parts of my rig are a little dated, but it shouldn't be struggling, as I don't push the sim settings too hard and they're certainly not maxxed out.

I'm stumped

Edit - See pic 1 as an example. Nevada IA Cold & Dark Start mission - VRAM has gone as high as 17GB / 140% when panning my head around!! This can't be right. Reducing textures to MEDIUM does improve it slightly, but struggles to hold 36 FPS (ASW auto).

Pic 2 shows the Tomcat on a IA Cold & Dark start and the kind of numbers I get.

Pic 3 shows the Phantom on a IA Cold & Dark start.

Pic 4 shows the Apache on its IA Cold & Dark start mission. (ASW has kicked in as I would expect)

Cockpit texture sizes are insane.

That’s what I was kinda thinking.  DCS is already no where near optimized for VR in general, so its a shame that this module makes it worse.

Afghanistan still 80% minimum VR, Syria same, Kola 70%

It takes me nearly 2 days to do a fresh install with all modules, maps, campaigns and the like. Admittedly, my internet speed isn’t great but I wouldn’t wish a fresh install on anyone.

[fjacobsen]

Setting Textures to Medium fixes it for me with very low impact on graphics fidelity, but having 4 or 8K textures in the cargo compartment is overkill and totally unnecessary.

Look how gorgeously the F-4E looks and that with almost have the texture size and in two cockpits (WSO & Pilot)

[Talisman_VR]

Yes, horrible.    I presume the glass cockpit will not help this. 

Happy landings,

Talisman

[Talisman_VR]

Yes, extremely low fps, very bad.  What a shame.  

Suppose glass cockpit will not help much.

Happy landings,

Please, do correct me if I am missing something or I'm doing something wrong, as I have only basic knowledge.

 

This is what I have done:

1.- Extract all .dds from Cockpit_CH-47F_Textures.zip

2.- Load all of them in "XnResize" https://www.xnview.com/en/xnresize/#downloads (the first one I found, there are probably better options out there)

3.- Action -> Preset 50% and Action -> Rotate unchecked

4.- Output -> select folder and Output -> Format: same as original

5.- Convert (took ~10min on my end)

6.- Zip all the dds created back into the original Cockpit_CH-47F_Textures.zip overriding them, and then paste back the file into [..]\Eagle Dynamics\DCS World\Mods\aircraft\CH-47F\Cockpit\Textures

I don't do multiplayer, but I assume it won't pass integrity check

 

EDIT: needless to say, make a backup of the zip file before overriding it

I don't care about the Chinook... Give me back my fps, I fly a Hornet. So, fly Navy Beat Army

Thats exactly what I did, but f.ex the text for the Parking brake and vents is now black.

I guess Your filesize became appr. 0.49GB or so.

[Darcaem]

Correct, that's the filesize.

I've been flying this afternoon and I haven't seen anyting wrong. But I'm flying in VR with quite low settings, maybe in higher settings it does look worse and cause artifacts?

[Darcaem]

Is this the parking brake text you were referring to? This is in pancake mode with the higher settings I use for mission making, I don't see anything odd... No idea what could be happening

Well, I tried it and it made hardly a noticable difference. The crux for me was reducing textures to medium. On high textures it was asking 14.5Gb of VRAM, I only have 10. On medium textures it's around 8Gb and same scenarios that had performance problems on textures High are now smooth again. I don't really see the difference between medium and high in the cockpit.

[Deezle]

I resized just the cargo area textures by 50% which reduced the texture file by almost 2gb. However it made no noticeable FPS difference for me. Putting the game on medium textures makes a huge difference.

[Marshallman]

OK Ive got mine sorted now..

Clearly dont need the high level of settings I was flying with in the past

40% Vram....... Hope this helps someone

Regards

[sasquatch98]

Add me to the it’s running great group wasn’t quite as smooth as I’d like last night but noticed msaa had been turned off by the update turned that back on and it’s perfect. You would expect msaa to decrease performance but it seems to end up putting more load on the cpu with it off for some reason. With it off my processor was a few degrees warmer than normal but my vram was 4 degrees less than usual and it wasn’t maintaining the usual 99% utilization I normally see.

Per me il CH -47F funziona malissimo sul mio Quest 3.

Nessun problema con l'F -4E 80 FPS (frequenza di aggiornamento scelta dall'Oculus ).

Anche l'AH -64D funziona benissimo.

Forse le texture della cabina di pilotaggio del CH -47F sono troppo grandi .

Le texture della cabina di pilotaggio dell'AH-64D sono di 1,3 GB mentre quelle del CH -47F sono di 3,5 GB !!

 

 

Idem for me (Pico4)

VR performance in this module is 10-15 FPS lower than all my other modules that run at about 68FPS on Quest 3.   Including Huey, Apache, Kiowa, Hind, Blackhawk Mod, and several jets.  Can’t afford to loose this much FPS, almost unplayable.  Same settings and same map.  Did repair, cleanup, deleted save game shaders and FXO files and no difference. Any ideas?  Thanks.

 

Same, I have a 14900k, 4090, 64gb 6400 ddr5 ram, m.2 and this is the first time I've seen dips in FPS in VR on a quest 3. Everything else is butter, still playable, but no where near anything it's fine, get near <profanity>... throws a fit. Gotta be the huge textures in the cockpit, don't get me wrong, the cockpit is extremely good looking, but I'd rather a smoother experience.
