TextureManager::processPendingRequests & CullJob tanking studio performance

Hello, I was trying to edit this place [TESTING] Ventura Developer Build - Roblox when loading into it today it decided to start tanking in performance. Please note it did not do this 2 days ago.



Upon looking into microprofiler it seems CullJob and TextureManager is taking above average ms.

I have attached the latest log and the microprofiler reading in the private content for staff-only.

My device specifications are:
Operating System: Windows 11 Home 64-bit (10.0, Build 26200) (26100.ge_release.240331-1435)
Processor: Intel(R) Core™ Ultra 7 265KF (20 CPUs), ~3.9GHz
Memory: 64GB DDR5 6000 MT/s
GPU: NVIDIA GeForce RTX 5070

Studio Version:

Beta features enabled:
3D importer in ACE
Assistant Mesh Generation
Dragger QoL Improvements
Face Capture
glTF Export
Improved COnstraint Tool
Improved Studio Solid Modeling Controls

New video API
Proximity Prompt Indicators
Reimport
Revamped Asset Manager

Expected behavior

I expected roblox studio to run smooth like it always has with this device.
Note other developers in the teamcreate are experiencing the same issue.

I am still experiencing this issue and its making studio unusable.

This has also been happening in live games, and it’s fairly annoying in tandem with the recently noted horrible performance with CoreUI (ExperienceChatMain, etc). For me it’s usually these wavy spikes on the microprofiler. It mostly seems to be CullJob, even when there’s barely anything on-scene, even to the point of a BSOD (reported by a few users for a game I work for, and myself especially)

Just started getting the processPendingRequests problem after using Studio for a couple hours, no clue why. I don’t know if it occurred during the weekend/previously in general as I tend to restart Studio frequently but it makes Studio pretty much unusable after a while. No abnormal CPU, GPU or memory usage either, and it subsides for me after restarting.

Unsure if it’s related but I also am getting this error: Failed to upload TexturePack (Reason: PublishService AssetUpload failed. Info: Unknown Error ErrorCode: Unknown). PBR textures may not be visible in game. Change a TextureId property to retry.

Have every beta feature enabled except AvatarAbilities and multi-touch

We have started experiencing this as well. Using Team Create, seems to happen more often with more users connected to the server.

Each person has to restart Studio several times per hour to resume getting 60fps.

this is happening to me too
except they arent answering me now when i sent them my microprofile

This has been happening to me as well. For me, it gets very noticeable when having a lot of textures in a place and sitting idle. Despite my efforts to work around the problem by disabling texture streaming entirely (among other reasons), the issue is so much more pronounced in this release. The texture manager is clearly broken :frowning:

Running into this issue currently in studio and unable to do much without constantly restarting.

Update: This flag appears to be a culprit as turning this off completely got rid of the lag. If this isn’t it, idk what did

This issue seems to happen for people with the “MaterialVariant: Alpha Mode” beta enabled. Once all our team members disabled it, we have had zero performance issues.
