Well you say your CPU is OC @ 5ghz in your sig but in your screenshot it is at 5.5ghz.. which CPU Specifically do you have? and for the record I idle at about 36c asnd when in the main menu of DCS it is about 46c. I could check ingame temps but I doubt I am hitting 90c+..

Unfortunately I have the same. I had to uninstall the patch. I play on a laptop and after the patch the fans go crazy even on the start screen and the case heats up like an oven. Oddly enough after starting any mission the load on the processors decreases but is still higher than before the patch. DCS becomes unplayable - my wife is screaming at me to turn off that hair dryer!

[LawnBoy.DCS]

I can confirm that temperature reaches 70 degrees Celsius approx during initial load and stays that way while idling at the main menu.

It is not to the point of being unplayable (performance seems pretty good, actually) but CPU usage shouldn´t be high while sitting idle at the main menu.

@BIGNEWY or @NineLine - can this be looked into?? I don’t have a baseline from last patch so I cannot confirm nor deny this.

Logs attached:

Updating to 2.9.16 adds +20°C to the CPU temp, in idle in the menu and in game during a mission.
Reverting back to 2.9.15 reverts everything back to the temps I had before the update.
Re-updating again to 2.9.16 adds the +20°C in back so there is clearly a problem somewhere.
I'm going to stay at 2.9.15.9599.1 for the time being so reverted back again and the temps went down with 20°C.

oh no - i installed that revert file and it went to some backwards update from 2024 - I lost the launcher and lost my campaigns

I downloaded the file, inserted into Root folder, ran it, and it erased my campaigns and dragged me back into 2024.

Also, after the last patch it seems to me that the cpu temperatures are higher than in the previous version of DCS. I haven't measured it exactly yet, but you can hear that the cooling hums more than usual. My CPU is Ryzen 7 9800 X3D.

[BIGNEWY]

Ive asked the team to look into it, it seems to be an AMD thing. I am using INTEL so can not test it personally. 

Can anyone check AMD efficiency mode, by default it should be on but some disable it. Let me know if you had it disabled. 

thanks 

 

 

[BIGNEWY]

The team have reproduced and have made a report.

Can't find where I need to do that (Google doesn't play along this time).
Does it refer to the C-State in the BIOS? If yes, I have it on AUTO.
BTW, I didn't change any such setting in between the updates and when reverting back to 2.9.15. all is normal again so it must be something within DCS latest update.
Also, FZG_Immel has an Intel CPU...

[BIGNEWY]

Thanks for checking. 

Yes seems its a mix of CPU's, just not affecting some but affecting others. 

Im running a Intel® i9-10900K water cooled and I am not seeing the issue. 

But its reported now and the team will get to the bottom of it. 

thanks

Hi folks,

AMD 7800X3D and same issue here.

 

[MoleUK]

5800X3D here, I wasn't monitoring the temps on menu before but I was monitoring CPU usage.

Before patch, two cores would peg to 100% usage constantly, with very little usage on other cores. So overall almost always around 13-16% CPU usage with SMT on. I never thought the two cores stuck at 100% was normal behavior, but it's been that way for a long time and is a widely reported problem/behavior.

After patch on menu, CPU usage is all over the place. Lots of sawtoothing. Overall usage up to mid 20's to 30% usage, so it's definitely increased the load significantly. In a high airflow case that's resulting in 60c just on menu, which is high vs other games where I frequently only hit 60c+ in gameplay if that.

ETA: I found some old SS's, I was previously idling on main menu at like 35-40c at worst.

I downloaded the patch last night but havnt played it yet.

Has anybody seen an increase in CPU related performance that mirrors increased CPU utilisation and temperatures?

I run a 9950x3d and il be interested to see using Process Lasso how this patch is working with both the cache and performance CCDs and if its any different to the last patch.

[Renko]

Can confirm this too, i have a AMD 5800X and the temp has raised

I see about the same ... however, my DCS feels noticeably snappier, including the Mission Editor, load times seem lower and the time to exit to desktop is also lower, so I don't have a problem with this increased load per se, as long as the performance is better than before.

aye. my fans have always spun up when i run dcs. i have an 11th gen intel i9 and a 3090. my first few experiences since patching has been noticeably snappy too. i have headphones. so i do not even here the fans. by the time i close dcs and take off the headphones, the computer is back to normal. i have no baseline to see whether the temps are more than before. sounds like a hardware issue. maybe  or dcs is using more of the cpu than it has in the past. i see it as an improvement.

That's why he specifically wrote about "modifying for your desired version". You have to edit the file and type in exact DCS version number you need (in this case the one which we were on till Tuesday), not just blindly launch whatever you find on the internet.

There's still hope, though. Your campaign progress is stored in Saved Games location (not at home ATM, so can't check in which file exactly), so if you install correct version this time, I believe you should get your progress back again.

Having the same issue or system is ramping up big time with increased utilization/temps.  Also have been getting crashes with just opening or creating new missions when changing maps.

Same issue here on my AMD CPU

I also only use a headphone but in general I put it on my head moments before the mission start so I can hear the difference clearly and see them in the Afterburner overlay.
My fans do rev up too when launching DCS but they spin down again when DCS arrives in the main menu. With 2.9.16 they don't spin down after entering the main menu.
On a normal instant action mission in 2.9.15 (or older) the CPU temp in the main menu sits around 52°C while going up to the lower 60's in the mission.
In 2.9.16 however, the CPU temp in the main menu sits already at 74-76°C while in a mission it stays at that temp.
There's clearly a difference between the 2 versions. It might be snappier (also my feeling) but for people who want to run things quit it's a setback, for people who run their system already quite hot in 2.9.15, the temps reach max in 2.9.16.

Another thing I noticed is that "sometimes" after a mission using the new instant generator, DCS will not close down to desktop and refuses to run again when closed through the task manager until a PC reboot. This didn't happen in 2.9.15 either.

Hi all

 

Same issue here. Intel(R) Core(TM) i9-14900KF   3.20 GHz, RAM 128 GB, Nvidia RTX4090. Fans are at full speed and core temp has gone up since last update, before the last update it barely made any noise, all in VR?

 

Has anyone know if it has been reported to ED

please go read the dedicated thread i linked.. Most people have this. Plenty documented

 

I dont want to run DCS until it pushes my CPU at 100°. 

FZG_Immel Your CPU has a thermal limit of 100C it doesnt mean its going to die at that temp, its just throttled to keep it safe under that temp....if it got above that, I would be seriously concerned. I have had a i9-14900KS fail on me due to the intel issues and it wasnt for the issue of it going to 100C. Have you updated your BIOS and all your MB drivers?(this is important if you own a 13/14 gen Intel cpu) there are issues with Nvidia drivers too atm, with more than a few having enough issues to warrant a revised driver update to correct the issues...not something Nvidia does willingly or lightly. I'd do as Big Newy asks and try replicate the issue and deliver the log and anything else to help them resolve this. Me personally, I have no issues with the latest patch, works like a dream! 

[FZG_Immel]

I confirm this happening with Intel, non OC.  13900k here. I have a 14900k sitting in a box in case this one burns away.

Yes yes. don't worry.

 

My old CPU intel died because of this about a year ago. It's been replaced by intel, and I am now running it with latest BIOS and safe setting (at a loss of performance of course). I even have a 14900k that is sitting on the side that I bought until my 13900k would be replaced.

 

Clearly there is an issue with the latest patch. never had such high temps since I updated the BIOS with the new intel 'safe' settings

 

I have no log to report, as I have no crash myself. just very high temps

forget about my sign. this was before my intel CPU died 1 year ago. I am now running the Intel safe BIOS and settings, since they clearly have issuee with gen13/14 CPUs
