Performance difference between 16bg and 32gb of RAM

Hardware & System
#1

Watch this space. I’m upgrading to 32gb from 16GB in an hour and will post results here.

Currently, I have a more-or-less stable 60fps at 1080p Ultra High+ in the countryside, with occassional 5-second freezes (no idea where these are coming from), and occasional FPS drops that don’t seem to be linked to on-screen visuals. In towns, depending on the number of buildings and AI, my FPS drops to about 45 and can even go as low as 30. Performance seems to get worse the longer I play. My spidey sense says there’s a memory leak happening, but that’s a different topic for a different day. The game is installed on a Samsung 960 pro, and I use a 1080TI, so best-case scenario for graphics and storage. The CPU is a 6600k at 4.6Ghz, so that could become the bottleneck but it should be enough to see a performance difference from the RAM, if there is one to be had.

Will post results in about 1 hour.

There wont be a discernible difference. The only thing that would have an effect regarding RAM is an overclock or upgrading to faster RAM speeds. In the Steam recommended system requirements at least an 8 thread CPU is recommended while you’re running on a 4 thread/core CPU. You do meet the minimum, which is 4 cores. But that is the cause of those drops to 30 FPS and 5 second freezes.

Edit


You can find your CPU on there as well and even with a 1080ti it can’t get higher than 77 FPS avg @ 720p, with probably much lower minimums.

8700k will be the next upgrade. But I already get 60fps at 1080p, I just want to increase minimum fps. Will let you know how it goes.

I have 24GB of RAM and last night while I was in susau (think that is how it is spelled?), I looked at my ram usage and KCD was only using right at 4.5GB of ram. As large as the game is, you would think it would use far more than that.

#5

The minimums are exactly the problem. Towns will murder your current CPU. But I do agree with Bagel94, the game should be allowed to use more RAM and definitely needs to be optimized further. Right now even 16gb isn’t being used fully, let alone 32gb.

#6

I currently got an AMD FX-8370 and its stays decently below 90% usage most of the time, can’t say so much for my hard drive. That thing is almost constantly at 100% usage.

Interesting. My system has 64GB, so perhaps this is why I’ve yet to see any significant FPS/lag performance drops from a potential memory leak. But I’d have to say that the game’s overall fps rate seems abnormally low on average. This happens regardless whether you’re doing a sandbox exploration of the country side or a town. Or doing a quest activity. FPS just seems really low. Don’t know if that’s related to the long screen loading times associated with every aspect of the game (from simple NPC dialogue to loading those movie length cut scenes).

Anyhow, bookmarking this for future. Thanks for sharing.

edit: KCD is in dire need of a performance optimization overhaul across all platforms. Hopefully they’ll address this by next update

this game just seems very rough and really in dire need of some optimization. tbh most people have a lower setup than you so their game experience must suck. i’m running 6600k, 980, SSD, 16gb ram

i get about 50 fps on high. moved down to medium to get 70pfs for now but the game still stutters for no some reason all the time. other people have been posting the same issue. the stuttering doesnt seem to to be related to graphics settings as it doesnt get better or worst depending on the graphic settings. my freezes are less than yours. maybe 1-2 seconds only.

Most of performance issues are tied to CPU used 100%. try looking at this new mod, I didn’t tried it myself for the moment but I will do tonight :

#10

Huh. I’m running a i5 7600k with a Radeon rx 480, 16 gb, and SSD. I get no freezes or stutters and run on a mix of ultra high and very high with shadows on high and get a solid 30-55fps in all areas. Towns drop to 30, but I grew up playing at 30fps so it doesnt bother me.

#11

Thanks for the feedback. Turns out one of the RAM modules was bad so I got a refund. It’s a sign haha. Gonna take the chance to rethink where I put the money. I’m now thinking of doing a part exchange to get an 8700k and an ASUS Maximus X Hero. A lot more money but I should see a big difference in almost every game, especially KCD. (From my current 6600k)

#12

I have 32gb… But the game and windows have never gone above 11gb.

#13

Update - Definite improvement going from 6600K @4.6GHz to a 8700k @ 5GHz. The game doesn’t use multicore very effectively, nor does it use all available RAM when it seems to need more. So it’s definitely not making the most of PC hardware, a lot goes to waste. Anyway, I now have perfect 60FPS 1080p at Ultra High ++ (All distance sliders on 100%) apart from in some parts of Rattay, at certain times, when the min FPS can drop to 45. Long story short, I expect perfect 60FPS gameplay across the map after a couple of optimisation patches. Seems the best way to fix the performance problems in this game is to throw a shit tonne of money at it. I no longer have the random 5-10 second hangs I used to get, even when it was running at 60FPS. Micro stuttering has been almost completely eliminated, and more of the potential of the 1080TI was unlocked.

The game was not optimized well and probably has memory leaks, it’s why it constantly crashes on console.

#15

Running i5 3570k overclocked, 16 gigs ram, installed on samsung 850 ssd, evga 970 4 gig ram and my fps outside towns 60 fps, in towns it can drop to 45, the lowest ive seen is 37 in rattay towards the far west gate is near the armorer and alchemist.

I run ultra on everything except shadows, post processing and shader which run medium and water is at high. Even combat is still fluid with a lot going on at once. LOD is cranked at a quarter away from full while everything else is maxed.

performance is as expected for my machine and being an RPG, it doesnt matter as much in the towns, cutscenes always default to 30 fps.

#16

I have 64gB with top end i-9 CPU.

Experienced the same exquisitely FUBAR technical issues.
