I can currently load P3D v4 on my system and see 15gb+ system memory use.  Yes, I have to dial up settings... but the point is... it is already possible to use up 16gb between the OS, background tasks and P3D's graphics demands.

Goodness. I have P3D too and even all settings on Max, and under heavy rain, clouds, AI, and high-end add-ons, never come close to 10Gb.  lol   Sooooo, wondering.

Well, the thing about RAM is you always have the ability to upgrade by swapping in a set of new DIMMs.  It's a generally bad idea to combine dissimilar memory modules, so the "ability to put in more" is really not there beyond a relatively short period after which a match for your current DIMMs won't be manufactured any longer.  So I think buying what you need now, with the option of completely replacing that memory later with a matched set of mo/fasta/betta modules is a more viable plan.

Best comment.

No reason or need for 32 Gb for current sim.... Maybe in 5 years @ P3D V6  Having 16Gb is more than enough no matter how high your settings go. Or, are you doing something else on your computer while simming thus the need for 32Gb of RAM?  No wonder you're having stutters, and 15fps.   Hahaha   Come on, guys!  Just solved someones' problems.  🤣😂

There are more settings than just the UI sliders, for one.  Since I don't sell memory chips, etc... I've nothing to gain by telling people to opt for the 32gb versus the 16gb.  It's an honest recommendation based on a great deal of experience.  Might want to take that into consideration.

No matter what i do, no matter what addons i use, ORBX, heavy airports, FSL320, PMDG stuff, whatever, i've never ever seen my P3D v4 over 6GB. Lots of clouds, flying online in IVAO with its own AI traffic representing other virtual pilots, 20h intercontinental flights, never ever disable scenario and very very high settings.... Nope, never over 6GB so i have no idea what you're doing with your PCs.

Just happy that mine is like it is: Less sticks, less money spent, better overclocking capability, less heat...

No, I set the settings to see how nice the sim could look and noticed that certain settings could really chew through system memory.  I don't rely on the swap file as a good way to use more memory.  I will be doubling my own memory in the very near future.

I'm guessing you fly GA, low and slow. I'm predominantly an IFR flyer and the slowest aircraft I fly is a Pilatus PC-12. For longer flights over land it's a Learjet 25 but the serious high-speed ones are reserved for Concorde. Mach 2 over water probably doesn't eat much memory even with 3rd party airports at either end and a couple hundred Ai.

They would have to be extremely complex airports to use that much memory and even though v4 Concorde is yet to be released it's a relatively simple aircraft compared to the modern glass cockpit jets with all their fancy displays.

LOL... ok, I give up.  There will be a point, with P3D v4, where you may find your 16gb isn't enough... you probably won't remember me telling you so.

You appear to be losing patience with me because according to my survey there's a reasonable case for staying with 16Gb. Lots of people are running P3D v4 with 16Gb of memory and apparently aren't having problems.

I've told you how I fly but you haven't reciprocated. Surely if you have lots of photo scenery that will be a factor. I only run a couple of other applications to support P3D none of which are heavy users of memory.

One question though. If I want to push cloud textures up to 4096 would that make a case for 32Gb? Or would that be handled by the GPU memory? That could be a deciding factor.

What I'm trying to ascertain is what in P3D uses memory and what uses GPU memory? I won't be ordering the system until Monday so I can still change things. One thing is for sure. More RAM now makes more sense than the 2080Ti over the 1080Ti and will cost a lot less.

Convince me.

No.  And 4096 cloud textures combined with even moderate AA at 4K resolution will really clobber your GPU in the vain attempt to sharpen inherently fuzzy-edged objects like clouds.  That's like trying to make water less wet.  🙂

Thanks Bob. But why is AA even a consideration at 4K? Surely there's a strong case for switching it off.

Because AA is needed any time the size of individual pixels becomes big enough to be resolved with the naked eye at the chosen viewing distance.  So that means a big (e.g. 50-inch+) 4K monitor up-close at ~1m viewing distance will still need AA, where a 30-inch display at that same distance probably won't, because the pixels on the smaller monitor are small and dense enough to where your eye can't make out the very small jaggies.

You must be psychic! I was researching pixels per inch this morning in relation to a new UHD display. 32" monitor has benefits over a larger TV display.

It seems unlikely I'll need AA for a 32" UHD. I failed to mention the smaller display probably wouldn't need the burden of AA.

640K ought to be enough for anyone.............................

5 Pages discussing RAM, we are going to run out of RAM typing and reading..🤣

Why buy something that won’t be used? I still have two free slots so might be able to add another 16Gb when required. But memory speeds may have moved on by then.

I’ll never buy XP. P3D only here.

Fair enough Ray...I would have said that a couple years back....but now I totally love having both sims for different reasons.
