resolved 2.9 BETA - Extreme FPS drops after few minutes (DCS MiG-21,Caucasus)

[Molnija1985]

Hello,

first sorry for my broken English. 

I am updated my DCS to 2.9. If I play my own training mission for DCS MiG-21BIS (Caucasus), so I have problem with extreme low FPS drops (3 - 5FPS) every few minutes. Any time I have normal FPS, but after few minutes my FPS drop to minimum, FPS drops takes a few seconds (5 - 10 seconds). This status lasts since the update to version 2.9. 

My HW: intel i-9 12900K, 32GB RAM, RTX 3080, 2x .m2 (DCS installed on .m2 disk), 32" ASUS monitor
DCS Version: Non-Steam, classic client version  2.9.0.46801

My settings:

I translated keywords, to English: 
Vysoký - High
Nízky - Low

Any ideas on temporary workarounds - in my setting (while maintaining quality)? Thank you guys...

I got the same issues, big freeze and computer total freeze often

[Tzigy]

That's kind of weird is it affecting only the training mission? or everything else is freezing as well? your settings look good for your card I would probably turn off anything to do w flat shadows (blur), try with and without vsync, just the usual turn on and off one settings at a time trying to isolate the problem and you know the usual advice as well if you have any mods that you activated before I would get rid of everything. I have similar system except 3090 card and everything is running super awesome after the update, using DLAA

  You may be encountering the core parking conflict issue described here:

You can try this workaround which seems to work for many users: https://www.dannymoran.com/windows-cpu-core-parking/

[Molnija1985]

Thank you for answares.

@Tzigy, no, i not use any mods. And I play only my own missions for my eastern airplanes (Yak-52,MiG-15, 19, 21, Mi-8,24), but I suppose that it will be a generic problem independently from DCS modules or missions. 

@Flappie thank you for you workaround. It is this regural bug, will it be fixed by ED? If yes, i will wait for fix. I really don't like to make system intervention, i.e. to the registries. Alternatively, could you please tell me what the intervention specifically means, whether it can have a negative effect on the operation of my PC?

Again, sorry for my english...

[Flappie]

I hope it will be fixed sooner than later, but I have no news to share so far.

Try the "High performance" (or "Max performance") power plan in Windows Power options, then tell us if it works for you (it's supposed to disable core parking among other things).

[sze5003]

I have high performance power.plan enabled. With a 13900k and 4090, I disabled HAGS in windows and it ran a little better.

But the longer I fly, the worse performance gets. To the point where even in the menu I'm getting freezing and stutter, frames drop down to 5 at times. This is in VR.

[Molnija1985]

Hellou @Flappie, 

i set power options on High Performance:

Vysoký výkon = High Performance

However problem with freezing continues to persist. Maybe it isn't so frequent, but it's still freezing. DCS is currently unflayable for me  

This is my brutal responses:

Thank you for you time...

I have got the same issue my friend. I have started new topic to not let it die between other post.

[Molnija1985]

 

@Mateo I think it's already reported as a bug, so that there are no unnecessary duplications of bugs. It is big performence bug, probably the biggest one I've met in 15 years in DCSk...I hope ED fixes it quickly. Sorry for my broken English my Polish neighbor
 

[Mateo]

You might try hyperthred CPU if you are able for hyperthred CPU in BIOS settings. It might solved my stuttering, but I need more test to be sure.

[Molnija1985]

Hello,

@Flappie any news about resolving this critical bug? Current after latest beta update is situation most worse. Now I have FPS drops also in main menu or, map. editor  DCS is unplayable. 

Any know workarounds are not working for my 

Pls. fix this bug as soon as possible.

best regards

P.S.: sorry for my broken English...

Molnija

 

[Flappie]

I have no news to share at the moment. Devs are still investigating.

[Molnija1985]

Hello,

Hi, 

we are working on a server issue currently related to performance for the next patch, but I am not aware of a specific issue for the Mig-21 and low FPS. 

can you attach your dcs log and dxdiag so we can look for more clues.

can you attach the miz or track replay from the specific mission so we can take a look. 

When I test on my system all seems ok, wondering if it is mission specific?

[Molnija1985]

Hi,

sure, I will summarize all the necessary information and send.

Thanks for your interest, for me DCS is a matter of the heart - for which I actually have a PC...and I permanently change my PC every 5 years because of DCS

best regards

yep its a passion for many of us and I share your 5 year pc change strategy also

[Molnija1985]

@BIGNEWY or anyone from ED/TFC...please heeeelp: 

Just to be sure, I repeated the test and am sending all the findings:

HW:
CPU: intel i-9 12900K (without OC)
RAM: 32GB RAM (without OC)
GPU: RTX 3080 (without OC with latest update 546.33 from 12/12/2023)
HDD: 2x .m2 
Monitor: 32" ASUS
TrackIR: v5 
Joysticks: Saitek X56 + peddals

SW:
OS: Windows 11 Pro 64bit 22H2
Other system sofware: WiseCare 365 PRO, ARMOURY CRATE

Prerequisites:

DCS version: NON-STEAM
NEW_My account: RussianKnights
DCS Beta (2.9.1.48335), was installed from previous versions.
Installed Mods for DCS: None
Installed language: Czech (Čeština)
Modules aircraft: DCS A-10C, DCS F-86F, L-39, M-2000C, Mi-24P, Mi-8MTV2, MiG-15Bis, Mig-19P, MiG-21Bis, Mirage F-1, P-47, P-51, Yak-52
Modules maps: Nevada (free, due to the purchased DCS A-10C), Caucasus, Channel (upgraded to 2.0),  Marianas, Normandy, Persian Gulf, Sinai, 
Modules others: Combined Arms, China Asset Pack, FC3, WW2 asset pack

My current setting:

Occurrence of bug:

• from upgrade on 2.9 version (Until the arrival of the long-awaited version 2.9 with DLSS support, this bug did not occur.)
• occurs regardless of setting
• today I tested this bug on other maps and DCS modules...default map Persian Gulf and F-86 and Mirage F1 and bug is occurs too, so it is not map or DCS module dependent
• NEW_the bug occurs in singleplayer, I haven't tried multiplayer yet, but I assume it will be the same, I will try it on request

Description of bug:

• occurrence of unexpected FPS drops, e.g. from 60 (with enabled Vsync) to 8 FPS...also tested with VSync disabled with the same result.
• the FPS drops occurs mainly when switching views (F2, F3) but also in the standard F1 view after a certain time....
• during the one-hour flight, I am in the FPS drops for about 20 minutes

Proposed temporarily workarounds by ED  @Flappie : 

• Set "High performance" in Windows Power Options -> not working
• Workaround described on this page https://www.dannymoran.com/windows-cpu-core-parking/ -> not accepted this workaround from my side, I am afraid to changes in registers where I do not know the impact of the changes

My own mission where is bug occured:

see attachment USSR_1984_Caucasus_SHOOTING_MiG-21Bis.miz

*but as I already stated, the error also occurs on a completely newly created map (independent of the selected map) where I put only one  aircraft.

Logs from DCS:

see attachment Logs.zip

Logs from DXDiag:

see attachment DXDiag_log.txt

Any screens with bug:

Ive tested the mission on my system and not seeing any fps hit, was around 150fps for me. 

Consider setting a higher pagefile, currently its to low, make sure there is plenty of space on the drive also.

Tuning Tips
 
Turn down Anisotropic Filtering.
Turn off SSLR.
If you have FPS issues, try turning off VSYNC in graphics settings.
Set Water to Medium or Low.
Turn off SSAO.
Set Preload Radius to max. 60000.
Consider using DLAA.
Set Shadows to Medium.
Disable civil traffic.

let me know if you notice a difference after. 

thank you

[Molnija1985]

Thank you @BIGNEWY for quick answar....I appreciate it.

Of course, I also tried different settings, but they have no effect on the occurrence of this bug:

screen from low setting with AAF and SSLR turnoff:

I will try to increase the size of the pagefile..

 

Many, many thanks...

[BIGNEWY]

Something else worth trying.

Rename your dcs folder in saved games, keep it as a backup. 

then restart DCS it will create a new folder, login, reset settings and test the mission again. 

do you see a difference? 

[Molnija1985]

@BIGNEWY ouuuuu, my new UK best friend...damn it...it looks, that if I set up my PageFile on disk C., so this realy fix my problem! Thank you so much...right, after Thom Yorke, Irwin Welsh and Danny Boyle you are my second favorite person from the UK!!!! Thank you...

I'll test it a little longer tomorrow to be sure, unfortunately I don't have much time today...
