Do I need a page file with 64GB ram?
I would rather think that CS would dump more stuff into the page file (which by essence is much slower than RAM itself), even while the page file is running of an ssd. So what do you guys reckon? I have DDR4, 8 strips of 8GB, 1,066Mhz each (in dual channel 2,133Mhz), but in my configuration they run in Quad channel mode. Currently I had this thought about making the page file the same size as my ram, but then occurred to me that if CS is going to use the page file more, it will actually getting slower. Should I just lower it again? The game seldom uses over 25GB of ram actually.

yes, the game crashes without a pagefile no matter how much RAM you have.

At 64 GB of RAM, windows will already make a page file up to 128 GB (twice the size of your RAM) for a total of 172 GB of memory. I think you'd be safe on memory. That's like 12,000 assets. lol

But Windows like to keep as much stuff in RAM as possible. This way it doesn't need to load it in from page file as often. I find it will try to keep half empty for easier swapping, then it will compress the system RAM, kind of like a pseudo-page file.

But you should always have a page file. If you run out of memory, it will cause an allocation error and crash your program.

But your total memory equals your RAM plus your page file. So just because your RAM is only 24 GB used, doesn't mean it isn't using much, much more memory.

What you are meaning is called "SuperFetch", but that service I have disabled. I also disable the hiberfil.sys service that puts everything in memory on disk in case the computer goes into sleepmode. I do use a 4 GB ramdisk for temp/log and other minor Windows files that normally will be deleted after use. At the moment of speaking I have Steam open, Firefox with 1 video in YouTube paused and that's it. Memory usage is now around 8GB, but that is including the 4GB ramdisk. Firefox and Steam use about 1GB together and all the other 3GB is devided about all the other smaller programs and services in the background. I do have a lot of disabled services on my computer (I actually undressed Windows 10 as much as possible). Anyway, the amount of free memory is 56GB right now. How would it ever occur that CS will take up ALL that remaining memory (considering my GTX 1080Ti has also 11GB of Vram, if that does anything) and has to address the page file? My 'theory' is actually, with this amount of ram I actually should keep the page file to a minimum to force the game to use mostly the memory itself, and not the relative slow page file. That would increase game speed.

You're not understanding the pagefile. Just because the page file is being used at load time, doesn't mean it is constantly being used when you run your apps. Most of those assets are just sitting in pagefile doing nothing at all. The core of the game is very small and it keeps only the assets used on the map into RAM. The rest are on the pagefile until used in your city. To use up all of your RAM, you'd have to plop down 4,000 unique assets in your city.

My typical city has a couple hundred without workshop. Most cities I help other with are only using a few hundred out of the thousands they have subscribed.

Used or not used I rather have them in my ram, which I have plenty off than sitting idling in the pagefile. Point taken is that RAM is just faster than the pagefile if the asset is loaded at any given moment.

You'll still need a pagefile as mentioned previously, you can try letting windows control it with that much ram or set it to x1.5 max if you have issues then try x2. Not many ppl have that much ram so a need for a large pagefile is quite important, for example if you used 32GB then you would definitely need to set it to x2 or x3 as the game ate up 27GB when i installed my extra sticks to make it up to 32GB.

Yes, I understand what you mean on your system using RAM you paid for, but in all seriousness, my system can load 200 assets on my new NVME SSD. So, I know I can't tell a difference of 200th's of a second of lag time. And that is generic NTFS file system, not an optimized for RAM page file system which is much faster. But even on my laptop hard drive only does about 33 assets per second, which 0.03 seconds is still extremely fast in comparison to our reaction times.

But it's really not a big deal at all. It's more an issue of OCD. lol I know I'm guilty of that.

For example, I reinstall Windows 2-4 times a year because it fells laggy and not as responsive as I like.

I'm also on a first name basis with our Comcast repair tech, and he even gave me his personal number to speed up the process. I got lucky with our Comcast here in town. They have really good service of any ISP I've ever used.

The idea is that I still want to buy an NVME drive, but it has to be a Samsung drive, so I can easily clone my current Samsung EVO 860 1TB drive to that new 1TB drive.

Okay I have been testing the page file. I have set it now to bare minimum. Initial size 1GB, maximum size 2GB. So far, no issues at all. Removing a lot of double crossing mods solved a lot of problems.

@MarkJohnson, if you have to reinstall Windows 2 to 4 times per year you are definitely not doing something right. My installation is already 4 years old, and it also was cloned before (to this Samsung EVO drive). My Windows is still as snappy as ever. With Windows 10 you have to know what you can turn off, because, lets face it: Windows 10 is a lot of bloatware. But luckily you can turn off a lot of unnecessary stuff. My tip for you would be: Install CCleaner and with that tool you can disable a lot of startup items, services and also de-install a whole bunch of Windows 10 programs you will never need. (Who needs "People","Weather","Money","Office","Candy Crush" and all those other useless programs. Also CCleaner can clean up your registry, and removes entries that lead to nothing (broken entries).

I already use the paid for ccleaner, but all options are available in windows already. Just not in one program. lol Although it does have a uninstaller that actually uninstall completely. Windows leaves stuff behind in anticipation of a reinstall. I just visit a lot of suspect sites and install suspect programs. I just find it easier to reinstall than troubleshoot anymore. It takes maybe an hour to reinstall my main apps and I'm good to go. Then restore my other items from backup at my leisure.

But most of my issues stem from messed up windows config files and too much of a headache to deal with and track down.

I highly recommend the Samsung Pro models, they are quite a bit quicker than evo. If you can afford it, the Intel Optane drives are insanely fast. But the cost is way higher than the performance gain.

no you dont need a paging file, 64GB is more than enough for this game.

i run this game with 64GB and it never touches the paging file.

Yes, I do need a very large page file, specifically for this game only.

but only when using a ton of workshop, of which 90 per cent isn't even used in the city. lol

comment didint quote you, it was clearly to the OP, no you dont need a huge paging file, upgrade your ram and you will be fine.

If you want to prove all those who commented about setting pagefile wrong then you could easily take out 32GB or even 48GB and test for yourself, then we'll watch you eat your words.

you literally answered your own question there... no paging file needed if you have enough ram or upgrade it....

your not proving anything here aside from giving BAD advice that was done around xp and hardware limitations.

its 2019 and hardware is plentiful and not very limited in terms of gaming, no one needs paging files for gaming, you can literally disable it and not have a single issue, just because this game leaks memory/ect.. doesnt mean you should be running a giant paging file.

upgrade your ram.

You're like a stuck record, take your ram out and prove us wrong lol
