solved Dcs-world - Low Frames GTX1080

[MbR2XgD]

My graphics card has low frames(60,42 and 24 very quickly). I don't know how to fix it.
I try to change the "graphics.lua",  I change the default settings from Dcs without success.
GTX1080 is too old? I cannot fly anymore.

My current settings:

On the top left very small(frames) and on the right side my PC(Low FPS):

Hi - until very recently I was using a GTX 1080 (with i5-9600k, 32GB RAM, 1440 monitor, in a fairly low-end system) and getting high 60-70 FPS with higher in-game settings than you have set.  

Then suggest you check out the various YT videos on how to optimise settings (Spudknocker has a particularly good one which includes NVidia Control Panel settings) but there are plenty of others.  More recent ones include specific settings for multi-thread to ensure your system is making the most of the new MT.

Then it's a question of experimenting to get the best "sweet spot" for your system vs game settings.

IMO you should be able to run reasonably high settings with FPS in the 40-60 range with a GTX 1080 in MT as that's what I was getting.  It did take a bit of research and "tweaking" to get it working like I wanted it.

Good luck and happy experimenting!

Can I show your dcs Settings? please, I deleted my "dcs.openbeta" folder and create a new one(default). Now my fps is 60 to 40 variable without Vsync.
Which resolution do you play dcs? FHD? I can play FHD only. Actually, I never try 4K. I'm not crazy. Dcs-mt is impossible to play.

Thank you @Hipster

Unfortunately, I have good and bad news.

The bad news is I cannot fly anymore, my GTX1080 is too old. I watched the spudknocker video with no success.
In the next(2 or 3) years, I can buy a new PC. My GTX1080 is Galax Exoc very limited.

The good news. I don't need to buy modules or maps from dcs anymore. I can save 60 or more dollars.

Can be a lot of things causing this so let's start with ideas.

VRAM full - try with textures: medium and terrain textures: low.

CPU OC fail or overtemp (I see CPU temp over 77^oC) - throttling problem - disable OC for testing, make sure your cooling is sufficient.

Remove any apps running in the background - some input devices come with some drivers and apps that can mess with DCS.

Upload your \saved games\dcs world\logs\dcs.log - if you're using any mods - remove and try again.

Run DCS slow repair and clean. Try also new clean DCS profile.

It's not your gfx card fault and it's not too old, unless it's faulty h/w of course.

I agree - until a month or two ago I was happily seeing decent FPS (60+) using GTX 1080 and DCS MT.

@MbR2XgD - can you confirm if you are GPU limited?  Your video suggests you're not maxing it out.

OK. Here is my list...
My CPU with Watercooler is 33°C ~ 80°C it's normal. My GTX1080 is Overclocked I cannot change it(82°C is normal, max 85°C temp).
Dcs-world MT is impossible to run(100% CPU). My Dcsworld has Gripen, Super Tucano, and Foxhound(horrible mod).
I tried "dcs_update.exe repair" only. I will try to "dcs_update.exe clean" and "clean profile" too.
ReShade 4.9.1(I need to update). "Dcs.log" is attached. There is no monitor, is TV only, but I noticed my TV is always 4K
and my Windows resolution is FHD. I changed the Nvidia default settings for "dcs.exe".

PC Idle(1% until 6%):


Dcs Idle(20% until 30%

It works for everyone. What do you mean impossible? I suspect you have some bigger system problem here outside of DCS.

Proper clean command is:

DCS_updater.exe cleanup

https://www.digitalcombatsimulator.com/en/support/faq/repair/#2463807

Clean profile means renaming saved games\dcs folder. The new one is created then.

https://www.digitalcombatsimulator.com/en/support/faq/startup/#1445924

Factory OC card doesn't count as user made OC attempt.

Come back after removing the mods and texture settings lowered trials. Your attached log is almost empty.

I can run Dcs MTwithout 100% CPU but isnt stable. I prefer the Dcs without MT yet.

1 - Are you running the game on SSD or HDD? A: SSD 1Tb- R/W: 500MB Speed
2 - Also 80 degrees and above on the CPU/GPU will cause thermal throttling which will cause stutters and fps drops.
A: Yes I need to by a new thermal paste

I forgot. I installed an App that I can change the OC settings but I have no ideia how to change.

My Hardware is too old or with a lot of problems, my OS too, so I cannot fly anymore.
I installed the "Gigabyte Smart Fan" and there is no more 80°C CPU and GPU.


You can see my video, there is no more 80°C CPU and 80°C GPU with Dcs MT:

At this point I recommend just completely wiping your OS and re-installing it to something like Windows 11
A: The Win10 has 2 weeks. It's new

You are probably have all these issues because your OS is full of bloated software and programs.
A: My SSD(500G). It's new too.

Reinstall windows and reset BIOs to default settings.
A: My Bios settings it's OK.

I think I found the problem. I'm not sure yet.
My MB has 32GRAM and supports up to 64GRAM. Dcs no MT running Mig29C map Caucasus.

Hey all,

I have been seeing the same issues since a couple of patches now. Often when there is an F14 (now an F15E as well) in the mission or as soon as someone changed their livery.

I dont know in how far this is an actual bug in the game's engine, it is known that DCS does not or used to not unload certain things or objects even if they are dead or out of view so I would not be surprised if there is an underlying bug that causes this rather unusual loss of performance. 
Regularly I can play at 90 to 120fps depending on mission and terrain - with the Textures set to High (which I had set it to since I started playing DCS in 2021) I quickly get limited to 20-40 fps near the ground or when looking inside my cockpit, which is very odd to me since it used to be fine.

I was able to fix this problem by lowering my Texture Setting to "Medium". DCS then behaves as usual and I simply expect my RX5700XT not to be able to handle DCS with its 8GBs of GDDR6. (both on MT and ST).

Hope that helps.

For transparency, here is my PC configuration and my DCS Settings:

CPU: AMD R5 3600X
MB: MSI B550 Gaming Plus
RAM: 32GB@3200Mhz CL16
GPU: Aorus RX5700XT OC (8GB GDDR6)
DCS running on a 1TB SATA SSD with Windows Pagefile set to 28gb

(apart from MT doing wonky stuff [Access Violations], DCS has never crashed on me with a Memory Issue since manually troubleshooting the "Out of Memory" and "Bad Memory Pointer" issues and setting the Pagefile to an adequate size. You dont need to do that I just thought it might be of interest)

I don't know yet. When I start the NS430, the framerate changes to 20, 60, 47, 80, 24, 70, etc...
Now the F15E and F14B the framerate is very low too.

This is my GTX1080(Caucasus map, mig29c and dcs ST)

I give up.

Dcs-world works perfectly at 60fps FHD but suddenly there are a lot of problems.
I found many tutorials with no success. I don't know if my Hardware is too old or dcs bugs.

What kind of problems?

You failed to provide dcs.log after the changes/repairs/cleanup you were supposed to make.

Edit: I'm sorry, missed your log from 12th Jul.

Ok, I've checked the most recent file - dcs.log. No mods - great, 2k resolution with MSAA, you've changed the card to 3060Ti 8GB - so what's the problem now? Stutters with NS430 only? Might be the module itself:

Tried to resize the pagefile to 32GB already?

Edited July 19, 2023 by draconus

[MbR2XgD]

@draconus Yes, my new card and the same problem. The problem is low FPS with 1080p and 2k, dcs st and mt with MSAA, vsync on/off.

The stutter is the F15E, F14B, and NS430 modules too. I tried to change the Windows settings with that site:

The more you tinker with the drivers and windows the less control you have over it all. I hope you do revert the changes when you don't gain significant improvements. Especially the last one (disable full screen optimisations) can cause trouble in DCS. Your fps is generally good/high until the stutters come - these are more like freezes in your case, not normal few ms stutters people usually talk about.

Can you disable NS430 in DCS Module Manager just for testing? (looked fine until you turned the Garmin on)

Do any other highly demanding 3d game stutter too?

Tried to resize the pagefile to 32GB already? (seems like I have to ask one thing at a time)

Tried with new clean profile already? (you do it by temporarily renaming "\saved games\dcs world" folder, the new one is created then)

Tried with textures low/medium already? (just to exclude RAM/VRAM overloading and swapping)

In your last screen grab your RAM is 98% utilised which is absolutely going to cause performance issues but DCS is only using 20. What it using the rest? How is your swap file configured?

Also, the NS430 is VERY memory intensive, especially with the moving map, and absolutely will cause stutters with 32GB of RAM even if your system is otherwise very healthy.

A: I don't remember anymore but It's Dcs-mt only with 98% RAM (GTX1080). The other programs are less than 10%.
My computer is always 10% or less running in normal mode(Idle).

A: Yes. This is not happening in the earlier version of dcs. it's new. My last Video with Mig29C and NS430 with GTX1080(No stutters)

That doesn't answer my questions.

DCS is using far less than 98% of RAM, what is using the rest while you're running DCS? You are out of RAM so you either need to stop the other things that are using it, get more RAM or make sure your swap file is properly configured on fast storage.

Take that first screen shot again and don't cut it off - let's see everything because you have other apps using 12GB of RAM (far more than 10%). What are they?

4GB is very likely not sufficient swap file if you're maxing out RAM. You need to increase it if you can't reduce RAM usage or upgrade RAM. What storage is it on and what else is on that storage?

The NS430 behaviour is not new, it's been happening for a very long time. Check out the thread that was linked, it was started in 2018.

A: I uninstall GTX1080 with DDU(Windows SafeMode no Network) and new Nvidia drivers(RTX3060ti) without Gforce Software.

Can you disable NS430 in DCS Module Manager just for testing? (looked fine until you turned the Garmin on)
A: Yes. The Mig29C is running 100 or more FPS.

Do any other highly demanding 3d game stutter too?
A: No. I tried the Call of Duty Modern Warzone and other games. Unreal Engine 5 and Blender. No Stutters or Freezes.

Tried to resize the pagefile to 32GB already? (seems like I have to ask one thing at a time)
A: I changed. Windows It's better now because I can edit and render 2K my videos with Blender. 
There are no stutters in Unreal Engine 5.

Tried with new clean profile already? (you do it by temporarily renaming "\saved games\dcs world" folder, the new one is created then)
A: Yes, I renaming dcs folder, I have 2 Ssd's, one is Windows and another is Dcs. I Deleted the dcs and installed It again.

Tried with textures low/medium already? (just to exclude RAM/VRAM overloading and swapping)
A: Yes. the same problem with low Textures and Terrain Textures.
