Is increasing RAM from 32GB to 64GB a smart idea?

[Ahdidaas]

I said I reset my pc to remove everything on it so I only have DCS related stuff.  I know fully well how to tweak everything on my pc (nvidia settings, cores, priority, affinity, etc...).  I simply wanted to get some advice on whether the value was worth it to upgrade.  It seems above some folks are getting a bit heated?

Let me put this at rest, I did the upgrade, I see my memory now going into the 50s on the Contention server last night.  I was on a FARP, starting up my apache when someone dropped a cluster bomb next to it.  It was pretty awesome being in the middle of all those explosions, and the performance was very good.

If DCS is your jam, then you should do it.  :case closed:

Well it is a good idea if you play on those BIG MP Servers like Contention as they do use alot of RAM. if you are just playing Single player in semi smaller mission it probally is not needed..

 

Either way only the end user will know if it is worth it or not once they do the upgrade.. but do not expect FPS Increases or the like.. Glad it was worth it for you..

 

EDIT: Also the best way to know if you need more ram is to play your missions and then check RAM usage..

Makes sense .. thanks y'all!

Admittedly, DCS World in VR is so amazing, whatever it takes to get a beautiful looking scene to wreak havoc in is worth it, imho.  

Started Operation: Agile Spear again, cranked up the fidelity, etc..  Zero stuttering.  I love it.

Only do it if you have 64GB of RAM! As a first step, do what you said and you will see that your computer will not crash! Then turn off the page file and you will see that your computer will not crash!

It recommends 9 GB for the paging file and I have 0!

Here is the DCS world without the paging file where I play in multiplayer where DCS World uses much more memory!

The page file was invented a long time ago because there was not enough physical memory. I'm sorry you don't try it. Nowadays, you can put as much physical memory in your computer as in a server! There is no difference, except that it does not stress the SSD. Simply, if there is no paging file, only the physical memory is used, the speed of which is dramatically faster compared to the SSD.

I have 64 GB of RAM with 4 GB of VRAM and everything on High preset has never crashed since DCS World 2018. It can only crash if it runs out of memory!

As long as you only fantasize about your computer crashing and don't try it, you won't experience it.

Only DCS World approaches 32GB of memory usage without a paging file, nothing else!

 

Are these your current specs/screengrab? It is showing Virtual Memory (Windows Pagefile is now called Virtual Memory) and your showing 64GB Virtual Memory. Or is that of something else?

While a GPU could use system memory when it runs out, that would now cause you graphics to look like a flying discolored jittery potato. Think about the speed of GDDR6X VRAM on the GPU vs accessing system memory through PCIe bus. This was a very common use case in laptops in the past that called it a feature.

DCS does not use 32 RAM. If it has 32 RAM, it will be enough for DCS. The bottleneck here is the 3080 and his VRAM and the operation of processors on the MT version, especially if he has a series of 11, 12, 13 or 14. Gen.

 

 

I've had 32 gigs RAM and was using a total of 56 gigs when running DCS (8-9gb was used by system so about 15gb came sourced from the pagefile), so how did you come to the conclusion DCS doesn't use more than 32Gb of memory?

 

With my 3060ti, this had stuttering, shifted pagefile to an SSD, this improved, but upgraded to 64 and this issue was gone

I think you can agree a 3080ti is not a lower performing card than a 3060ti?

If you turn off the page file, it will be transferred to the physical memory, that's the secret! What you can read on the internet that you must use a page file is somewhat outdated, because in the past you needed a page file because you couldn't put 64GB or 128GB of physical memory in your computer!

This is also the name of the page file, an extended memory that is on the SSD or the Winchester. It is extended, so if you cancel it, it will not be extended to the drive and it will not use the slower drive.

I repeat, you will not experience the difference until you try it. You can see in the pictures that on an online server, 20+ players do not reach the 35 - 40GB usage without a page file. My memory usage is less 28000 MB comitted because the texture preset is Medium and the terrain texture is Low!

People often stick to their habits and find it difficult to change them!

With the micro stutters, try to disable Hotplug

I wasn't suggesting that eliminating a page file won't work, I was pointing out that your screen shot of sensors shows it enabled at ~64GB. Eliminating the pagefile for playing games when you have adequate memory, is nothing new and it's been done for as long as I can remember. Naturally, physical memory is better than virtual.

And this applies to GPU's too, on board GDDR6x memory as close to the GPU as possible is significantly faster than using system memory that is enabled in an already heavily used PCIe bus and that system memory is also slower. If having low VRAM were fine, we in the VR subset of DCS could quit buying $1k to $2k graphic cards.
