No suitable driver found

[Monash]

I have been experiencing very long (5 to 10 minute) startup times for missions in DCS in VR (Quest3+Link cable).  The main menu appears quite quickly, but loading up an instant action mission takes forever.  As part of trying to trouble shoot this I submitted my DCS log to an AI and asked it to suggest a cause for this issue.  It raised many issues, but key was the following ERROR: 

2025-05-12 17:13:55.993 ERROR   EDCORE (Main): No suitable driver found to mount mods/terrains/syria/assets/assetstextures.zip

There is no such file on my PC at the indicated location.  There is however a file called "AssetsTextures.summer.zip".

I have reinstalled the Syria map.  I have deleted (& backed up) the DCS folder in saved games.  I have no mods installed.  

Can someone shed some light on this problem.  I've upload the entire log file in case it is useful.

EDIT: I just realised I forgot to change the graphics settings after deleting the DCS saved games folder.  They are set to high for VR and that will be reflected in the attached log file.  However, that is not the key issue as the problem  of extreme loading time (and the strange attempt to "mount" a non-existent file) persists after I set much lower graphics settings.

hello

i do not have this file either. does dcs eventually open and run properly? how much delay are you talking about? do you have exceptions in your AV software for the pertinent dcs folders: install folder and saved games folder? you could try a repair. however, i have a feeling the repair will not find the zip to re-add. i suppose you could make a copy  of the zip and rename it. just a workaround. seems like a definite bug.

Hi Silverdevil

The mission will eventually load most of the the time, but can take up to 10 minutes more or less.  It is highly variable and can be reasonably quick one time then exceedingly slow the next time.

The DCS folder is excluded from my AV software.  The DCS folder in Saved Games is not excluded.  I've added this to the list of exclusions, but loading times seem unaffected by the change.

I have repaired (fast and slow) multiple times.  I've deleted and reinstalled the entire Syria map.

Error in the log doesn't mean it's critical. It still can work fine.

Mounting can mean creating a file, ex. in the temp folder, so it may be normal that it does not exist beforehand.

Try to set your pagefile to fixed size 32GB.

Check disks for errors.

My DCS installation is on drive D.  My Saved Games/DCS folder is on drive C.

Do I need to set the pagefile to 32 GB for drive C, D, or both?

One is enough. Choose the fastest drive, ex. M2 NVMe, it's usually system drive. I hope all are at least SSD type.

Understood.  I'll give it a try. All drives are SSD.

PS.  I'm experiencing other VR related issues with DCS, probably related to the recent updates to Oculus Link.  As a result, I'm going to step away from this for while.  Thanks to everyone who replied with helpful suggestions.
