Massive Memory leak since last update

[ggoodavish]

I played DCS before this latest update with high settings, with no problems.   After the update, I am now getting 83% of my memory being used by DCS, which results in massive lags.   Makes it unplayable.   I have a 3.2 GB speed computer, with 32GB of RAM and a Nvidia RTX 4090 video card.   I should not be having these problems.    The only way I can play now is turning all settings to low, which makes somewhat blurry cockpit textures, poor clouds, etc.    Not real happy about latest update.   What changed, and how can I fix this?   With my computer, I should not be having these problems.   Please spell out steps if you respond, so I know where to find the files, etc you will likely refer to.    Thanks for your help.   Here are my specs:

Device name    Greg
Processor    Intel(R) Core(TM) i9-14900KF   3.20 GHz
Installed RAM    32.0 GB (31.7 GB usable)
Device ID    BCB37B76-249F-415F-8AD0-689F893D8758
Product ID    00342-21333-28717-AAOEM
System type    64-bit operating system, x64-based processor
Pen and touch    No pen or touch input is available for this display

Attach your C:\Users\username\Saved Games\DCS\Logs\dcs.log file (may just be a text document named “dcs” if Windows is hiding file extensions). 
 

32gb RAM is not a lot. Add a custom page to your fastest SSD (only one page file, remove all others, eg Windows system managed ones) with Initial and Max values of 32768 click Apply, Ok, and restart your PC. 
 

You definitely shouldn’t have problems with those specs. I’m assuming no VR as you didn’t mention it. What problem are you actually experiencing?

I saw another post about not starting DCS as an administrator after the latest update.   I started it without administrator rights, and now it works great.   No more massive lags, even with high settings.  I am happy again!  Not sure why administrator rights when starting cause this, but oh well, working well again.

@ggoodavish Curiosity: how's the RAM usage without running as admin?

[ggoodavish]

Went from 83% to 70%, with 7GB used.  I have 32GB RAM, so those numbers don't look right, but heh, it works good, so not complaining.

It might look for files/settings that your user don't have access to or doesn't exist, because it's looking for them in the administrator profile, which you're not currently logged into.

On my PC I see DCS regularly use 48GB RAM, out of the 64GB I have. So depending on which mission you are running, SP or MP, problems can be expected.
Personally I upgraded from 32 to 64GB 5 years ago, and I'm glad I did. Some people on these forums have 128GB of RAM, and while that is likely (hopefully) overkill for at least the next few years, I admit I am considering it as well for when I upgrade next time.

How do i ensure DCS is notr running in Administrator as I am suffering horrific perfromance ssues... on occassiona i can hit 90FPS... then slump to 20FPS for a while before leaping back up to 70FPS
