[#4724] Sudden Performancedrops in Hatikvah's Choice 1 - Linux

[ColdRogue26]

Hello,

I've noticed it a few times already, never thought anything of it. It happened again today and I asked around in the discord, some people experience the same thing:
The Sector Hatikvah's Choice 1 causes massive fps drops. Not a constant one, like the Timelines Mission "The Fade" did, rather sudden ones, lasting longer the longer I play.
It only happens in Hatikvah's Choice 1, as far as I can tell.

Same save as the report about the jumping raptor.

I can capture a video, if needed, as well as supply any needed details about my system or X4.

System information and confirmation that your game is not modified would be useful. A video isn't necessary.

[ColdRogue26]

Game is not modified. Neither through creative start, save edit or mods.
Vanilla game with the 5 Major DLC, none of the small dlc.

Running Linux Native X4, not through proton

save file that stutters at least happened once

i have much lower specs but stutters happen in HC1 and freeze time increases linearly longer the game is played. this is very vague diagnostic but core 1 ramps up to %100 while other cores go down during freeze. stutters kinda line up with ships coming out of gate/superhighway. I think stutters happen in faction borders like HOP/PAR border too.

Also noticing poor performance in Hatikvah's Choice 1 when in combat. Yesterday evening it was dropping to 1 FPS in little stutters and hitches.

Was my ship (Envoy) and 1 NPC wingman vs about no more than 6 Small and Medium Xenon at any one time.

I'm still in early game. No player stations and not that many ships. No mods. Haven't noticed these FPS issues in any other sector. I'm assuming it's a CPU issue as obviously the 5070ti should be able to handle what's on screen. The only time I see a sustained dip in Frame Rates is when in the Volumetric Fog and asteroids in Heretics End and even then it only goes down to about 60 or 70 FPS at worst.

On highest graphical settings except Chromatic aberration OFF

Dynamic Frame Generation OFF
VSYNC OFF

Please provide a link to your savegame so that we can see whether it's reproducible.

Will do. Just need to reproduce it. Tried to just now and didn't experience the issues this time...

[chibiphoenix]

Noticed the same as well, will add a savegame later to help troubleshoot.

I initially suspected it might be the drones from the pre-placed defense station, but, it still happens with it destroyed.

It seems to happen the moment an enemy pops in and looks for a target or something, but, as said, I will add a savegame

[Drusas]

Here's a link to save file, Vulkan and dxdiag.exe output:

https://drive.google.com/drive/folders/ ... sp=sharing

I find when I reload the save the issue doesn't reproduce or immediately reproduce. It seems to be an issue after prolonged time / Combat in the sector.

One thing I noticed is that the performance stutters often seem to coincide with the red targeting frames appearing around new enemies.

[ColdRogue26]

Hello!

Kind of reviving an old issue here. I just played around with 8.0 again and noticed something.

Every time the frames drop, as described in Hatikvahs Choice 1 for example, my GPU is suddenly shown to only have 512MB VRAM max (According to steam fps counter). It happens repeatedly, but only ever when in combat.
I noticed it again this time in True sight, while HOP was fighting ARG. Should be able to replicate that using my previously submitted save.

I am inclined to believe the steam fps counter, as 512MB max VRAM would definitely explain the sudden frame drops, even when cpu and GPU show no abnormal usage otherwise.\
I hope this information helps with finding the source of the issue.

I will see if I can record a video of that happening and will submit it here via edit

Good profits to you!

Is that the nVidia GeForce RTX4070 Super with 12 GB VRAM as standard?

Yes, same hardware as my original report

[rudi_pioneer]

Same issue, oddly only on newer PC - occasional stutter in Hatikvah's Choice I, Second Contact The Flashpoint. I thought it was number of NPCs related but happens when space battles have way less units too.

Hello everyone, i have the same problems but i found the issue.

First of all my System:

• AMD Ryzen 9800X3D

• 64GB DDR5 4800 MT/s
  EXPO 1 = 5200 MT/s
  EXPO 2 = 6000 MT/s

• AORUS GeForce RTX 5090 XTREME WATERFORCE WB 32G

• OS
  Windows 11 24H2
  Windows 11 25H2
  Arch Linux (LTS-KErnel)
  Arch Linux (ZEN-Kernel 6.18.13) - currently OS

The Settings from the Game is not the issue, i try all of them. Low, Mid, High Grafics.

The Solution is:

Disable HyperThreading on the AMD CPU
and the Freez, Frame drops are gone.

The following Options can fix the problem:

• Disable SMT

or

• Enable GameMode (for X3D CPUs) this disabled SMT

Please Egosoft fix the HyperThreading issue.

[rudi_pioneer]

Good and bad news:

Bad: turning off SMT and turning on GameMode for X3D didn't help. I've confirmed in OS that they did what they are supposed to do (number of cores is halved)

Good: i was able to reproduce it and this save is right when stuttering happens at Hatikvah I (i've been in other busy combat sectors and there was no stutter, in Hatikvah I sometimes it's almost a second or more): https://e.pcloud.link/publink/show?code ... LdjprNvMr7

This is not correct. You`r CPU has the same count of cores. You don`t understand the different between phisikal and logical.
SMT stays for "Simultaneous Multithreading" and this allowed one core multiple independent threads concurrently.
And this is what you see inside you`r OS.

In my case a 9800X3D has 8 Cores and 16 Threads, this meens one Core can two threads concurrently.
The Core size/count stay by 8 before and after this setting. that's just an illusion.

EDIT: And yes in your savegame i have the issue again. interesting

Yea i'm pretty sure i haven't described correctly what i tested, it made sense at a time. Important thing for this thread is that SMT is off, game mode for X3D is on, and that my CPU is 9800X3D.

Just FYI I see this on a new game start on i7-6700, i7-7700k, and a i9-13900kf.
So please do not focus on AMD Processors.
Way to reproduce on anything start using Wayward Scion which is closest to HAT1
Upgrade the Nova so you can live long enough to test unless you think you are an Ace

"Me too" posts without the proper information (DXDiag, vulkaninfo, in-game settings) do not give us anything to work with, and add nothing to our investigations. Please provide that information if you're going to post in an existing thread.

Maybe someone can test this.
I started the game with the parameter: “-nodefaultlog”
and either it's a coincidence or there's a reason for it.
But I've been playing "Hatikvah I" for about 3 hours now and haven't had any performance drops yet.

I also turned SMT back on for my CPU.

But I couldn't find any default logs.
Is this option maybe deprecated? And this all is only coincidence?
