Camera Raw 18.3 - VRAM memory leak on RTX 5060 Ti (Blackwell GPU) causes 100% GPU load and extremely slow file saving

Question

Copia e incolla questo testo nel campo:System configuration:CPU: Intel Core Ultra 7 265KF	RAM: 64 GB	GPU: NVIDIA GeForce RTX 5060 Ti 16GB GDDR7 (Gigabyte), GPU-Z confirms 16,384 MB VRAM	GPU Driver: NVIDIA Studio Driver 596.36 (WHQL)	Motherboard: Gigabyte Z890 AORUS ELITE X ICE	OS: Windows 11 Pro 25H2 (Build 26200)	Photoshop: 27.6	Camera Raw: 18.3	Monitors: BenQ 2560x1440 (primary) + secondary 1920x1080Bug description:After opening RAW files (Canon EOS R6 Mark II, CR3 format) in Camera Raw and applying adjustments such as presets, masks, filters and AI-based operations (Denoise AI, Remove Object), the system progressively slows down until it becomes almost completely unresponsive. Saving a single photo can take over 60 seconds.Key finding confirmed via GPU-Z Sensors:After applying filters and masks in Camera Raw, VRAM usage reaches 15,937 MB out of 16,384 MB total (97% of available VRAM). GPU Load stays locked at 100% and Bus Interface Load stays at 100% indefinitely, blocking file saving. The GPU fans spin up and the entire system becomes sluggish, including unrelated applications.This is a progressive memory leak: after a fresh Photoshop restart, the first exports are fast and VRAM usage is normal. As Camera Raw operations accumulate, VRAM fills up progressively until the system stalls.Steps to reproduce:Open 20+ CR3 RAW files in Camera Raw	Apply a Lightroom preset to all selected photos	Apply masks and manual adjustments to individual photos	Use Denoise AI or Remove Object on one or more photos	Attempt to save/export — saving becomes extremely slow or system freezes	Check GPU-Z Sensors: VRAM usage will be at 95-97%, GPU Load at 100%, Bus Interface Load at 100%What I have already tried:Clean GPU driver reinstall using DDU in Safe Mode	Installed NVIDIA Studio Driver 596.36 (not Game Ready Driver)	Deleted TempDisableGPU files in %appdata%\Adobe\CameraRaw	Reset Photoshop preferences	Updated Camera Raw to 18.3	Verified GPU is correctly detected in Photoshop PreferencesTemporary workaround:Restarting Photoshop resets VRAM and restores normal performance temporarily. Using Edit > Purge > All also helps but does not fully resolve the issue.Note:The GPU hardware is fully functional. Gaming workloads (tested with Assetto Corsa) run perfectly with no issues. This bug appears specific to Camera Raw's interaction with NVIDIA Blackwell architecture (RTX 50 series). Multiple users with RTX 5060 Ti, RTX 5070 and RTX 5070 Ti report identical behavior on Adobe Community forums.

Same issue here with an RTX 5060 Ti 16 GB. Disabling "Use GPU for image processing" fixed it. Data below, in case it helps other users and Adobe.

System: Intel Core Ultra 7 265KF, NVIDIA RTX 5060 Ti 16 GB (PCIe 5.0 x8), 64 GB DDR5-6000, Windows 11 Pro, NVIDIA Studio driver 616.92. Photoshop 27.11, Camera Raw 18.7. Canon R6 Mark II CR3 files (24 MP), 20-30 images open in Camera Raw at a time, with presets, AI masks, AI Denoise and Generative Remove.

What I measured (a small script logged GPU and memory every 10 seconds for 12 working days):
- While working on a batch, dedicated VRAM filled up to 15.3-15.6 GB of 16 GB, and Photoshop then pushed 3-9 GB of its GPU allocations into system RAM.
- At that point the GPU showed about 100% utilization but drew only about 35 W of 180 W, while PCIe traffic was saturated at 17-35 GB/s. The card was waiting for data over the bus, not computing. Saving JPEGs went from about 1 s to about 9 s per image, and AI Denoise practically stalled.
- Photoshop's committed GPU memory grew to 37-55 GB over a few hours and was not released after clicking Done. Only restarting Photoshop cleared it, so I had to restart every 20-30 images.

What fixed it:
1. Camera Raw > Preferences > Performance > Custom: "Use GPU for open and save" OFF. Export went back to 0.6-1.1 s per image.
2. "Use GPU for image processing" OFF. The VRAM build-up stopped completely: typical VRAM use dropped from 10.9 GB to 4-5 GB, Photoshop's GPU memory from about 10 GB to about 3 GB, the overflow into system RAM from up to 9 GB to about 1 GB, and I no longer need to restart Photoshop. AI features (masks, Denoise, Remove) still run on the GPU.

I also set NVIDIA power management to "Prefer maximum performance" for Photoshop, which removed the lag when moving sliders (between interactions the card was dropping to about 400 MHz and PCIe Gen 1).

I hope Adobe can look into the GPU image-processing path on RTX 50 (Blackwell) cards. I'm happy to share my logs.
