w.i.p CH-47 Performance Issues

[ST0RM]

VR FPS has been reported as extremely poor in the Chinook, already. We've been assured they're looking at optimizations, but unfortunately nothing has been passed to us to allow it to be played. 

[Digitalvole]

I came here to ask if the fps has improved, alas it seems not. I’d love to get the chinook and Afghan map, not yet I guess.

Hi,

I'm having real problems in VR (quest 3) with the ch-47, since it launched.

I have almost all modules and have tested in many maps but as soon as the full cockpit model loads in my FPS are very low (mostly below 10) in both single player and multiplayer, and often leads to game crashes. I feel like it may have something to do with all the digital screens in the aircraft. The in game performance even in the Apache is good and I can often get full 72 fps (on 72hz mode on the quest 3).

I'm running an overclocked i7-13700k and rtx 4080 and 64gb ram.

The DCS log is attached. Any suggestions are appreciated (I have attempted things like lowering cockpit display resolution but with almost no effect).

Many Thanks

Nathan

Hi, 

Can I ask you to do a mission with the CH-47F and then attach the fresh dcs log from that session. 

thank you

Hi BigNewy - thanks for your response!

I'm almost a bit embarrased to send it as weirdly I did both a single player and a multiplayer mission just now, and my FPS were better than I have ever had in the 47 - must have known i'd been moaning about it and got itself into gear haha. There were some fps drops and i'd say the average fps was slightly lower still than on other aircraft, but as i'm sure you'll see in the log i was getting 36 and above at times so was a lot better than the sub 20s I had been getting before. I dont think I had adjusted any settings before hand either.. so not sure whats helped!

Log is attached  

Many Thanks

Have to agree .  Chinook performance is by far the worst fps out of all my other modules..no matter what map..but Afghanistan is a literal sideshow on my crystal

Thank you for the log, 

I dont see anything obvious in the log that may help. 

It maybe worth removing the unofficial mods, deleting metashader2 and fxo folders and allowing DCS to create new ones. 

DLAA might be worth a try to see if you notice a difference. 

I have asked the team about more optimisation again, hopefully something can be done to help. 

thank you

One easy (partly) fix would be to simply give us the option to use 2K textures.

Especially for VR it wouldn´t decrease quality in any noticable way.

It´s really a shame for an otherwise fun Helicopter.

Amen! These 4K cockpit textures and the super high LOD model are killing things.

Performance for me drops by at least 25%

I have i9 13900K, 4080 super, 64gb Ram, DCS dedicated 4tb M.2 SSD, Windows 11, and use VR (Crystal).

 

[LuseKofte]

I can see the frustration of investing in high end PC just to have to tune down settings for one or two modules, I might find myself in that situation soon enough, but with my 3080 and old i7 I have no noticeable difference in performance cross the board. but my graphics is tuned down pretty much

[fjacobsen]

With the latest update it seems they have divided the textures into two:

Cockpit_Cargo_CH-47F_Textures.zip

Cockpit_CH-47F_Textures.zip

I tried the Chinook after the latest update. I noticed on S/P Syria, I've got smoother and flyable FPS in VR. Not stellar, but better. 
In Afghanistan, it's terrible. So this tells me that the map is also a major problem. 
Hopefully more work can be done, as FPS across several airframes have been negatively affected from the 24 Dec 2024 update.

It's all a matter of optimization, really. Like I said, we're working on it. 

Looking forward to the fix because as it stands right now its unplayable.

My Nvidia 4090 is melting with the ch47, all other modules are working smoooooth... But only the ch47 gives my a lot of stutters.

Is there a way we can help with the issue?

[av8orDave]

Man, performance on this one is bad. I have a 4090, 7950x, 64G DDR5, and VR in the Chinook is still nearly pointless. I see they were working on it in September. Still working on it?

I have a really old computer, and I did the texture resize mod, and it worked last fall, performance wise. But then, the Chinook was updated with some fixes regarding the texture loading or something. And now the mod does nothing for it, while it does for other modules.  

[Raven (Elysian Angel)]

Yes the only thing that does work is reducing Textures to Medium - just for this 1 module.

[Wood]

Yeh. That ain’t going to happen. I pay good money for the module I want to be able to use it as intended not degrade it so I’ll wait until it’s fixed

If you haven't seen it, @zbysiek made a script to reduce texture sizes. With it you can override only CH47F's textures, instead of reducing everythink to medium

The Apache also had some performance issues, as well. But, those got ironed out in a reasonable time frame.

I expect the same will happen to the CH-47, but it's surprising to see it take so long.

[LuseKofte]

I have huge issues loading this chopper in MP it is by far the worst in that regard. I think they know, this bird will be updated a long time ahead

[Crash *]

Optimization is progressing very slowly indeed. It is actually consistently poor.

Not only does the CH-47 mess up your gaming experience, other MP players also have a significant FPS loss when the CH-47 flies by or just stands around.

You don't like being seen as a Chinook pilot in MP.

Please improve this at last.

[scorpion80]

Is it progressing? 

[BIGNEWY]

when the team are ready to share news they will in the patch notes.
