Anyone with maxed out ram in game / memory leak

[Gruble]

I have been using this program for a long time and seems to help especially in parts of the Syria map. Go to options and turn on both options to clean ram at 80 percent. It seems to help free up ram and keeps it from maxing out. Let me know if this helps anyone. It runs in the background but uses almost no resources. Have a great evening.

Just tried it, great tool. Thanks.

[Gruble]

Great!

[firefox121]

how does it works, I download an executable, double click and nothing happens

[Gruble]

It should show up in your windows toolbar then double click it to bring the window up.

 

[PLUTON]

I took the liberty of trying it too and it works well. Thank you for the info

[DeltaMike]

Numbers?

Aren't we kind of throwing out the baby with the bathwater?  

[PLUTON]

Explanations Mr DeltaMyke please!

[Gruble]

I’m not sure of any numbers. I have 32gb ram and on the Syria map my ram usage will max out and my fps will drop unless I run this in the background.

The concern is, that DCS is gonna have to fill the RAM back up again anyway.  Perhaps it's a question of trading performance for consistency or something. 

[PLUTON]

Ha ok thank you for your explanation

[PD919]

Does this just dump RAM or VRAM as well.  Even a 3080 Ti will fill up its VRAM.  

[Gruble]

This just actively cleans your main RAM.

[pixie]

Thank you, I will give this a try.

It might proves helpful since a well known trick in VR, is to alt-tab out of DCS and go back after a while (a minute or so) 

I will let you know if this helps

I don't think that's what throwing out the baby with the bath water means ;).

[DeltaMike]

A tactical victory that fails to advance, or even works against strategic goals.

I have tried memcleaner for a few sessions and it seems all my stutters are gone !

This might  be a little bit soon to claim victory, and I should make some further investigations. 

So far the results are very promising. 

can anyone concur ?

[pixie]

So far so good !

@Gruble Thank you very much for the tip, in my case this memory cleaner tool is a blessing

Out of interest, how are you using this tool to clear memory?  During a mission, just prior to loading a new mission

It runs in the background and constantly keeps it low, when I've run it Syria ram usage is around 18-20gb without it it's gobbled up almost all of the 32gb.

I don't generally use it at the moment as I've not tested to confirm it actually helps performance at all, like @DeltaMike pointed out above, if you clear the ram then you might just be needing to fill it back up again.  I don't know enough about memory allocation/usage to quantify how well this works, more testing needed

[Mr_sukebe]

Agreed. Would be useful to understand the method by which DCS releases the use of memory.

 

In theory, preloading lots of textures and keeping them within available RAM is a good thing, as it should reduce the number of new fetches of data from storage.

[Gruble]

It’s really only beneficial if you are out of ram while it tries to load more data which happens to me if I don’t run this program. If I don’t, I get a big performance dip.

[pixie]

FWIW I run memory cleaner right before launching DCS... and forget it.

I haven't checked the actual memory usage of my 32gb with and without memorycleaner. Right now,  the VR stutters that were plaguing my game after a while seems to be gone. I can play as much as I want without restarting / alt-tabing DCS.

One possible explanation could be related to some kind of memory leak that fills the RAM forcing the system to swap data on the hard drive.Since the RAM is prevented from being maxed out, there is no swap file on the HD and no VR stutters. I know it seems simplistic as an explanation, but it's plausible enough to me.

I use this software as I said above
but since it works in the background why
I change missions my fps drop until I restart DCS?

That's related to running out of VRAM*, this tool only keeps the system ram clear.

*Reducing texture sizes, resolution, antialiasing and view distance will all help reduce vram usage, it's better with openxt compared to steamvr but still does happen.
