New data!

My most recent framerate drop occurred right after teleporting (using a teleporter, going to a station bar). As the teleporter doors opened, the geometry of the hallway took maybe 1-2 extra seconds to appear, letting me see the rooms beyond before the hallway walls popped in. And then immediately I got the drop.

Can you paste your config.xml file should be in: Documents\Egosoft\X4\<steam-id>
Also I'd like your current vulkaninfo output: https://www.egosoft.com:8444/confluence ... VulkanInfo

I'm unfortunately having trouble reproducing the issues with current betas, I understand it's still happening periodically right (in beta 5)?

That is correct.

Config is here: https://app.box.com/s/6vsayozn26sd3gnpl5cwsztwu9kcsiz2
Vulkaninfo is here: https://app.box.com/s/xamwhlya0fjoqj5v6m7opsbe2l175n5c

I encounter the problem seemingly regardless of graphics settings (I tested Ultra, High and Medium defaults).

Problem persists in beta 6.

Would it help to have another config and vulkaninfo file?
Currently playing a 4.10 modded game that's a few hundred hours old. But, happy to try out the beta on a vanilla start if it will help.
It would be a shame to miss out on the next release because of issues with radeon rx500 series cards.

I can report a change with beta 6!

Previously, the framerate drop would clamp my FPS to below 5.

Now, when the drop occurs, it will *either* clamp me below 5 *or* clamp me below 13.

No changes in settings.

4.10 B6

Ryzen 7 2700X (PBO) + RX 580 4G + 32GB DDR4-3200CL14 (4x8GB)

same here - i get drops to 5-15fps

often happens when i:
1. dock
2. start dialogue
3. go into bar/security/manager etc

happens in modded and unmodded game
happens "random" - like i can sometimes play for 1h without issue and then boom

noticed that my aggressive manual fancurve of GPU usually starts screaming 5-15s before drop happens

when i delete ShaderCache (via driver before gamestart) i can play for over 30min

when i experience those LAG/ low framerate i can simply change the texture settings (to any other i dont use) and it will work again for an undifined length of time

RX 580 4G
when i change to "high" texture settings i can play 5-10min normal and then LAG happens again
when i then change to "medium" textures i can play for 10-20min and then LAG happens again
when i then change to "low" textures i can play for 20-50min and then LAG happens again

so i assume there is a problem with X4 freeing GPU Memory of textures and when it hits a certain value it causes a middle-catastrophic failure that tanks the framerate to 5-15fps

I may be hitting the same issue on my Nvidia Geforce GTX 1060 6GB when I play in 4k resolution on low settings:
I'm playing with -nocputhrottle -nosoundthrottle -skipintro -showfps.
FPS as shown by the game drops to around 5 fps from around my regular 25-60 before.
Happens e.g. when docking at a station (e.g. Hatikvah's Trading Station, PHQ) and I also encountered it while flying (~6000m/s) in Tharka's Cascade from Family Zhinn to Hatikvah's Choice.

It usually happens after maybe 2h to 3h of playing, though I haven't really timed it.
I usually save when it happens, then load the save without restarting X4, which works for the first time I encounter the issue.
When I hit the issue a second time it usually does not help and I have to restart X4.

Lowering my resolution to 1980x1020 for my yesterday's game session and I haven't had any issues in >8h continous play.

Yes if a game usually plays fine then you get such a fps drop its almost always a vram issue.

Ego has been experimenting in opening up the memory limits so users with higher vram amounts can use their vram more i think to precache data im presuming. Guess its not fully stable and needs tweaking.

Im bumping this as i have the same issue i can get 60fps and it suddenly drops to 4fps and doesnt recover.
game ran smoothly on 4.0 this is a beta issue
i got ryzen 3600 amd 480 4gb gpu

New data!

Here is my current save game:

https://app.box.com/s/90n617cllipwagrkyij9jpio0pz4bcq7

Right now, I'm capping out at 8fps on this save, no matter where I am in the universe. The frame rate drop struck about 2 minutes before I made the save. And then, for the first time since I started having this problem (beta 1), quitting the game and reloading did NOT resolve the issue. A complete exit from the game and a reload of the save would usually give me back my framerate, but this time it has not (I've restarted the save 4 times, no luck).

So I'm both hopeful and confused. Hopeful that there is something in the save state that will help solve this usually intermittent issue. But confused because I was convinced the issue was a VRAM memory leak, but that doesn't make as much sense if the issue is appearing the moment the save loads.

At the main menu, I get 60 fps. As I'm loading the save, I have 30 fps. As soon as the save is fully loaded in, it tanks down to 6-8 fps.

Just tested on a new game, I'm not having frame rate issues. So it's not a sudden hardware problem, it's specific to the save I linked above.

What type of game start was it? I have tried out each Beta as they are released, on new saves and have had the frame drops in all of them.

Sorry, I should have been clearer. With the new start I didn't have the frame rate issues immediately like I was with the other save. I did have frame rate issues after a few minutes, though, as always. It doesn't matter whether it's a fresh save or my old 4.0 save.

The difference is that the save I had been testing with now gives the frame rate issue as soon as it's loaded, without exception. (It didn't before; it always used to take a few minutes at least.)
