Recommended download (for Vintage Story 1.22.0 - 1.22.7):
vsvaogc_1.1.4.zip  1-click install

Client only. Your server does not need this. Drop the zip in Mods and leave it zipped. If you extracted an older version, delete those old vsvaogc folders first or the game gets weird about it.

Ever notice Vintage Story feels great when you first load in, then a couple hours later everything starts hitching and FPS is just... worse? Yeah. The game sometimes forgets to clean up old 3D mesh data on your GPU. That junk piles up. This mod cleans it up in the background so you do not have to restart all the time.

No settings to tweak. No hotkeys. Install it and play.

You might want this if

  • Session starts smooth, gets worse the longer you play
  • Hitching creeps back after 45-90 minutes
  • Opening inventory / handbook / certain items seems to make it pile up
  • Turning graphics down helped for a bit, then the slide came back anyway

What it will not fix

  • Cranking view distance / lights / HD packs until your GPU is already maxed
  • Chunk stutter when you fly around like a maniac
  • Lag from the server

This is a memory leak fix, not a magic "max settings for free" button.

Optional nerd stuff

Type .vaogc in chat if you want to see queued / reclaimed / pending. Most people can ignore that.

Source is on the listing now (GitHub link up top) and MIT if you want to poke at it.

My testing

  • Game: 1.22.6
  • Box: Ryzen 9 5950X, 64 GB RAM, RTX 3090
  • Packs: TrueScale 128 HD on a vanilla+ multiplayer server
  • Before: ~150 FPS at the start, then slide + hitch after a long session
  • After: held ~152 FPS for 36+ minutes with no leak buildup (earlier high-settings run was closer to ~199 FPS)

Latest is 1.1.4. Grab that one.

For modders

Vanilla VAO.Finalize logs undisposed MeshRefs and never calls Dispose(). GL cleanup has to happen on the render thread. We queue those and dispose them there. No GC.Collect, no input injection. Related: #8488 · #9712

1.1.4 vsvaogc
1.22.0 - 1.22.7
1380 Aug 25th at 2:53 AM vsvaogc_1.1.4.zip 1-click install

1.1.4

 

Looked at the crash report from Solomob422. The NullReferenceException is inside Butchering EntityBehaviorButcherable.Initialize while an entity was spawning from a network packet (creative, flying into unloaded chunks). vsvaogc shows up under Involved Harmony IDs because we postfix ClientMain.ExecuteMainThreadTasks, same bucket as OptiTime. That listing is expected whenever anything on the main thread throws.

 

Hardening this release anyway:

- Outer try/catch on the Finalize prefix (falls back to vanilla Finalize on failure)

- Outer try/catch on the ExecuteMainThreadTasks drain postfix so a dispose/queue failure cannot crash the client

- Still no GC.Collect, no key injection, DLL-only zip

1.1.3 vsvaogc
1.22.0 - 1.22.7
238 Aug 23rd at 6:48 PM vsvaogc_1.1.3.zip 1-click install

1.1.3

  • Adaptive drain: 16/frame normally, 32 if pending>=64, 64 if pending>=256
  • - Hitch (>=80ms) still drains up to 256; no GC.Collect
  • - frameguard.json metrics written off the render thread
  • - Reusable percentile scratch; .vaogc chat shows version
1.1.2 vsvaogc
1.22.0 - 1.22.7
257 Aug 23rd at 12:16 AM vsvaogc_1.1.2.zip 1-click install

1.1.2 — DLL-only load fix. The 1.1.1 zip included src/. Vintage Story compiled that source and VaoGcMod never registered, so FrameGuard and VAO dispose never started.

1.1.2 ships DLL-only at zip root (modinfo.json, vsvaogc.dll) so FrameGuard + VAO dispose actually load. Drop the zip in Mods. Do not extract it. Delete any old vsvaogc folders first (dual-modid skips the DLL).

No gameplay or input changes. No GC.Collect, no key injection, no cursor warp. Hitch path extra-drains queued VAOs only.

Does not fix GPU-bound hitch at view 1536 / max lights / HD packs.

1.1.1 vsvaogc
1.22.0 - 1.22.7
41 Aug 22nd at 11:59 PM vsvaogc_1.1.1.zip 1-click install

1.1.1 — No render-thread GC.Collect. No key injection. No cursor warp. VAO queue + Dispose only. Hitch threshold raised so FrameGuard no longer pulses on every 28ms frame.

1.1.0 vsvaogc
1.22.0 - 1.22.7
34 Aug 22nd at 11:44 PM vsvaogc_1.1.0.zip 1-click install

1.1.0 — Initial public release.

Client-only Harmony fix for the MeshRef/VAO leak: queue undisposed VAOs from VAO.Finalize and call Dispose() on the GL/render thread via ClientMain.ExecuteMainThreadTasks (16/frame). Chat command: .vaogc. Does not change graphics settings.

@SalemStyles: Imma try this out haha thanks for the mention :)

Hell yeah, glad you're checking it out. For real though, huge thanks for TrueScale. That pack is what I run with and it looks incredible. Really appreciate the work you've put into it.

 

Hope to catch you out there sometime.

Cheers :D and can say this def takes the edge off long play throughs also we are working on something really cool atm that should bring truescale into the next realm :D 

SalemStyles, Sep 4th at 5:53 PM
@IllLeroySquad: i look forward to anything you put out. Ive built this mod with youre texture pack in mind.

cheers haha its been a labor of love this past year seeing what I can do with it. Got a big update on FrameForgeTSR coming out soon too next few days I imagine just finishing some backend stuff, optimizing some new features and adding several runtime avenues for frames that pair with opti time I also made it more compatible with it as currently it uses compute shaders for the temporal stuff so optitime shuts off a few of its features when it detects it which is counter productive. but working on it. so far it is a bit more tedius than I previously thought and a few harmony patches keep crashing I had to remove AO from it its going to be added to my shader mod same with my fogmod. but so far I can fly through big (NOT REDWOOD LOL) forests at mach speed with little to no lag cpu is uhmmmm higher than willy nelson but its smooth at least. next step is cpu thrashing and a few bottle necks I wanna be able to do big forests and redwoods with my texture pack and yes it has been mentioned a few times especially on modded servers haha I DO CARE ABOUT YOU ALL (and listen :P ) haha <3 

Zettin, Aug 26th at 1:42 AM

Does this work alongside the optimum client?

IllLeroySquad , Aug 29th at 1:36 AM (modified Sep 4th at 9:07 AM)
@Zettin: Does this work alongside the optimum client?

Should be fine in theory. Optimum is its own client, this is just a normal client mod that cleans up leaked meshes. I haven't personally tested the two together though, so if you try it let me know how it goes. After you're in-world, type .vaogc in chat. If it answers, the patch loaded. If Optimum already fixed that leak on their side you might not even need this, but they should not fight each other for settings or anything.Crash log me if something blows up.

theysa, Aug 25th at 10:49 PM

Hiya, this seems really good. Is the source available somewhere? I just personally dont install mods that I cant audit the code, too many things sneaking bad stuff into them these days so I'm a bit extra cautious.

theysa, Aug 28th at 7:45 PM
@IllLeroySquad: yeah fair enough. source is here: https://github.com/leroysquad/vsvaogc same 1.1.4 that's on here, mit. the zip is dll only on purpose.

Thanks! Could it add to the mods source on the moddb? Makes it easier for others to find as well. Really appreciate btw.

Thank you so much for this mod. When I last played vintage story half a year ago this exact memory leak was so incredibly annoying making me restart the game more often than I wanted to, and I'm glad to see theres a mod that fixes it now that I want to start a new world <3

Appreciate that. Honestly I just ran into the same pain, had the tools to dig into it, and figured if I could fix it for myself I might as well share it. Glad it's helping.

StrayFox, Aug 23rd at 4:19 PM

Does this mod have any conflicts with mods like OptiTime?

Solomob422, Aug 24th at 9:13 PM
@IllLeroySquad: not that i know of. if you have any crash reports send them to me ambassador.nki@mailbox.org

I actually did experience a crash related to those harmony ids. But it was in creative while going way too fast into unloaded chunks, though it seems to maybe be incompatibility with Butchery?
I don't actually need this fixed, since I can't recreate it. Just thought it might be some context

@Solomob422: I actually did experience a crash related to those harmony ids. But it was in creative while going way too fast into unloaded chunks, though it seems to maybe be incompatibility with Butchery?I don't actually need this fixed, since I can't recreate it. Ju

Appreciate you posting the report, even if you can't recreate it. I dug through it. The actual NullReferenceException is inside Butchering (EntityBehaviorButcherable.Initialize) while an entity was spawning from a network packet. That lines up with what you said: creative, flying too fast into unloaded chunks. Critical error is blamed on butchering@1.14.0. vsvaogc (and OptiTime) show up under Involved Harmony IDs because we both postfix ClientMain.ExecuteMainThreadTasks. The game lists every Harmony ID that patched that method whenever anything running on the main thread throws. So that line is expected noise here, not proof this mod caused the NRE. Still shipped 1.1.4 with outer try/catch around our Finalize prefix and drain postfix so a dispose/queue failure on our side can't take the client down. Grab it if you want, but for this specific crash I'd point at Butchering + entity spawn into unloaded chunks. Thanks again for the context.
