Persistent Stutter

[KidCharlemagne]

Hello all,

 

I'm out of ideas and could use some help. I've been playing DCS for about 3 years now, and have been struggling with stutters that whole time. These micro-pauses are much more pronounced in VR, and really take away from an otherwise incredible simulator. I've read just about every thread I can find with the word "stutter" or "lag" in it, and haven't been able to figure out my problems yet. Some background:

 

System:

Ryzen 5 3600X

GTX 1080 8GB

32GB DDR4 @ 2666 MHz

DCS on 1TB SSD, OS on 480GB SSD

Oculus Rift S

 

Settings:

Textures HIGH

Terrain Textures LOW

Civ. Traffic OFF

Water MEDIUM

Visib. Range MEDIUM

Heat Blur OFF

Shadows OFF

Res. of Cockpit Displays 1024

MSAA OFF

Depth of Field OFF

Lens Effects DIRT

HDR OFF

Clutter/Grass 0

Trees Visibility 75%

Preload Radius 150000

Chimney Smoke Density 0

Gamma 2.2

Anisotropic Filtering 4x

Terrain Object Shadows OFF

Global Cockpit Illumination OFF

Vsync OFF

Full Screen ON

Scale GUI PERSONAL PREFERENCE (Recommended: OFF)

PD 1.2

 

Things I have tried:

-Disabling Windows 10 Game Mode

-Uninstalling NVidia drivers with DDU, then reinstalling

-Disabling hotplug in autoexec.cfg

-Disabling Network adapter (seemed to work briefly, but couldn't reproduce)

-Turning off real-time protection in Windows Defender

-Starting DCS with no USB devices plugged in

-Closing as many extraneous services/programs as possible

-Uninstalling GeForce Experience

-New GPU (previously RX480)

-New CPU (previously Ryzen 5 2600)

-New VR headset (previously Lenovo Explorer)

-Disabling VR and flying on 2D monitor (~110 FPS, stutters still very noticable)

-Reinstalling Oculus software on different drive

-30GB paging file

-No paging file

-Paging file on same drive as DCS

-Making sure I don't have MalwareBytes installed (I don't)

-PD's from .8 to 1.5

-PD at 1.0 in DCS, 1.1 to 1.4 in Oculus Tray Tool

-Deleted FXO/Metashaders

 

I know there's more I've tried, I'll edit this post if I think of anything else. I've also attached my Log file here if it helps.

Anyone have more ideas?

You could also try this if you have not done this before.

Rename saved game folder for dcs open beta to old and let it generate a new folder for dcs. If it works, you can copy your config and other important folder back to the new folder created.

 

Are you using any mod, you could uninstall all and see.

 

You have got a system good enough to handle your vr headset and configuration.

I hope this helps.

Go to your saved games folder and delete the FXO and METASHADER folders contained within the DCS folder.

 

 

Then run a DCS repair, reboot your pc, hope for the best.

Hmm, if "disabling network" seemd to have helped...that reminds me of some users having stutter caused by other devices on their LAN like Smart-TVs, LAN-Printers, NAS, etc..

Set your DCS in OFFLINE mode, then DISCONNECT from your LAN physically ( pull the cable or disable the WLAN-device in DeviceManager ) and try again.

 

It sounds far fetched but some Pilots really had issues caused by other LAN devices

Thanks for all these suggestions. The first thing I always try is deleting the FXO/Metashader folders, so I'll edit my first post to add that in.

 

This afternoon I tried pulling out my ethernet cable, no luck there. I also tried renaming my saved games folder and allowing it to create a new one, but no luck either.

 

Something I noticed, however- the stutters were only present when disk active time was increased. There were considerable pauses with spikes up to about 50% active time on the C: drive, but the sim was smooth and stutter-free anytime the disk active time was low. Looking at Resource Monitor, the file with the most activity was AppData\Local\Temp\DCS.openbeta\~tr00007E2A.bin. Does anyone know what this file does, or if it may be causing stutter?

your problem seems to be related to Memory/SSD side. make sure SSD is not full and not partitioned and if you can do fresh clean install on another SSD. and try to run high speed memories like 3000MHz or above because Ryzen will work better with them.

It is Windows device discovery.

Thank you all for your suggestions and help! In the end I replaced my PNY SSD with a Samsung 970 Evo and the stutters have disappeared!
