PC Microstuttering

I had a little during the previous alphas, but there, the number has increased.

I'm lucky to have a PC that can run the game with the settings to max, so I tried all the possible combinations, but it didn't change anything.

I think it would be interesting to know who has no microstuttering (if there are players who haven't). This would help to know if it is due to some graphics cards, processors or others.

One thing is certain, something has been changed between A17 and A17.1 which has accentuated this issue.

I think, Roland, we (you ^^) could create a topic where only players who don't have this problem would communicate their configuration.

 
Please report if you do NOT experience micro stuttering and your config information.

I do, but very rarely.

Ryzen 5 2600x

GTX 1070

MSI X470 Gaming Plus

16gb DDR4 Corsair Vengeance 3000

Kingston SSD

Win10

*Play on dedicated server through BlueFang

EDIT: play windowed mode 1080

reflections off

water quality good

motion blur off

Kinyajuu and I looked at some code we thought could be causing stuttering and made a change for A17.1 which should have improved it. I have a 60hz monitor and don't really notice a problem. Kin tested it before and after on his 144hz monitor and it seemed better to him.

This is a subjective problem and probably varies with hardware, so we may not notice or deem it does not bother us, so those with issues will need to describe it in detail or we may never find it. Screenshots or videos could be very helpful.

 
Had microstutter in 17stable and I no longer have it in 17.1

Ryzen 1700

16gb ddr4

Gtx 1080 ti

Asus x370 mobo

Samsung SSD win 10

144hz monitor

1080p

Playing on dedicated server

Have also noticed higher and more stable frame rates, all settings on lowest except for textures medium

 
Im wondering if its possibly related to people's "System Timer" settings.... Such as "HPET" ( https://en.m.wikipedia.org/wiki/High_Precision_Event_Timer ) there's a lot of jankiness/conflicts between drivers/OS/Bios/UEFI/id10t all having different settings.

Mine is turned off so i have the lowest possible system latency (my OS/UEFI is highly optimized, so i really don't have many problems)

 
I had microstutter in A17.0 and now in A17.1 it seems to be fixed now, so long as I don't enable the 2 reflection options - then the stutter returns. Everything else is on high/best settings.

With all the movement animations, some ppl can find it difficult to notice the stutters, especially depending on hardware / software configs as you mentioned... but in flight mode, especially when going around an object... it's impossible for anyone to not see it.

Hope that helps in seeing it.

 
I have some minute stutter as of 17.0 stable. I host a game with 4 people including myself so some of the strain on my system may be from hosting. (We play usually for a few hours a night but hadn't played tonight so everyone hadn't updated to 17.1 yet, will give an update with more info if I have any change).

CPU: Ryzen 5 1600x

RAM: 16gb 3200mhz DDR4 Corsair Vengeance

Motherboard: ASRock AB350 Gaming K4

GPU: AMD Radeon R9 290

Game Settings: Reso- 1680x1080. Fullscreen. V-Sync. Anti-Aliasing on. Texture Quality- Full. UMA Texture Quality- High. Reflection- Low. Reflected Shadows- No. Shadow Distance- Near. Water Quality- High. Water Particles- 50%. View Distance- Medium. LOD Distance- 50%. Tree Quality- Ultra. Grass Distance- Normal. Motion Blur- Normal. SSAD- Yes. Depth of Field- Yes. Sun Shafts- Yes.

 
I did prior to getting G-Sync working with the new Unity engine. Now it is normally liquid-smooth, but once in a while it actually does a full stutter, like it is loading something off of an old EIDE disk or something, but normally only after thirty minutes or more of gameplay. The game is actually on a RAID0, so loading should never be an issue.

i7-6950X

32GB DDR4-3200 (Corsair)

1TB WD Blue on AHCI controller (OS, programs)

2TB RAID0 on RAID controller (two 1TB WD Black disks) mounted at C:\Games (Steam and other games here, duh)

Two GTX1070's in SLI using the high-bandwidth SLI bridge

Mobo is an ASRock X99 Extreme4

Dual-Layer Blu-Ray burner on the AHCI controller

750W Gold PSU (I forget the model)

Creative AE5 AUdio Card

Dell S2417DG 24", 1440p (2560x1440), 144HZ G-Sync Monitor

All in-game settings are maxed. I get about 40-80fps depending on the area.

 
Are those of you who are experiencing micro stutter playing with Vertical Sync turned on or off? The only stutters I ever get are clearly problems with garbage collection and tend to happen when spawns populate. I had some actual micro stutter problems after I had to rebuild this machine a few months ago. Turns out my video card was not seated correctly and was not ever switching into PCI-E X16 mode. It went away after I reseated it. That is the problem with big heavy cards. They can be a PITA sometimes.

I have not had any problems otherwise. I do notice that a lot of people play with V-Sync turned off. That may not be helping here. Also, make sure you aren't running any game specific setting changes in your control panel. Such as forcing AA or AF on the video driver end. This game does not like that at all.

 
17.0 I had very little stutter with 17.1 so far it has increased a lot. I have a 6500 skylake I5, GTX 1060, 16gb of ram, Creative sound card.

I had microstutter issues with vsync off, even with gsnyc active. Turned vsync on fixed it for me.

Is it micro stutter (several times per second) or just freezes every minute or when moving into a new area (loading/spawning)?

Is vsync on or off?

Is the monitor at 60hz or one of the high refresh models?

Are you using nVidia's fast or adaptive vsync or triple buffering or gsync?

I've never used gsync, but I would think it requires vsync on, since it is matching the vsync to the game's FPS.

 
Here is what i found after extensive testing and i will say this. A17.1 performance has improved vs A17 for my issue, it's not fixed or great but better at least.

I'm going to bin the term microstuttering and be very specific as i'm referencing frametimes. It's inconsistent frametimes causing the jarring motion certainly in my case and maybe others too. The problem is not related to cpu use, chunk loading, Zed pathing calculations etc. This is gpu / graphics specific.

Spec

  • i7 6700k @ 4.6Hz (all cores)
  • 32gb fast DDR4
  • 2080ti o/c boost around 2040Mhz core
  • NVMe OS / game ran from dedicate games SSD
  • Nvida CP : Vsync off
  • PC dedicate to gaming only, apart from Steam and light AV settings not much else runs on it (have other PCs for normal use)


Game spec

  • 4k & 1080p
  • Everything maxed out with exception of no dof / blur, only variable is reflection quality
  • Coordinates : 1034 65 656
  • Navezgane, Zeds off (so no CPU cost)


The short version for me at least is load Navezgane (no Zeds) go to the above coords and you'll find yourself in a kitchen. Try running around the kitchen with reflected shadows on low vs pretty much anything else. Ultra+ is obviously the extreme but it's jarring.

People bang on about fps but it's not that unless you have low fps. It's frametime.

4k - reflection quality low = fps 50's and good frame time

4k - reflection quality ultra+ = fps 50's / p*ss poor frame time (9ms - 30ms range, fps does not change)

1080p - reflection quality ultra+ = fps 60's (40% gpu usage) / p*ss poor frame time (9ms - 30ms range, fps gets better)

Poor frame times are like a sine wave, high / low peaks and it is the difference in those peaks that cause the issue. A worst ms frame time that is more consistent is much better than a lower ms frame time with high peaks.

I'll upload the screenshots in a second as it is easier to show.

54fps and a nice consistent 18ms frametime, it feels good no jarring
