Revit material browser slow

[Anonymous]

open the revit material takes 10 minutes why?

I purged only the unused "Materials" and "Material Assets" (Appearance, Physical, Thermal), and that fixed the problem.

Here it is January of 2022 and this problem still persists. I have a workstation with an Intel Xeon W-2235 CPU @ 3.80GHz 3.79 GHz, 80 gb of ram and an NVIDIA Quadro M6000 24 gb GPU. My SSD drive is dedicated to hosting only the Operating System (Windows 10 Pro) and programs, all of which are legitimate, no cracked software or junk from sketchy software companies. There is zero reason why changing a material should take 5 minutes. Not only slow, but is causing crashes about 50% of the time.

Check for missing images in maps, textures, etc.

Most of the time it is caused by missing bitmap files in Appearance Assets. First, purge unused Materials and Appearance Assets. Then, use material browser to try to find out the rest Appearance Assets that may have any missing bitmap files' paths and fix them. There's also some app in App Store can help you with this.

It's 2023 and the project browser is still the biggest grief when using Revit.
New topo functions are cool in 2024 Revit, but come on, can we fix this and make the browser function smoothly. Nothing I have ever read and tried has worked. 💀

Crazy isn't it? If it were my product, I'd say "fix this!". Especially if I had the resources that AutoDesk has. The software isn't cheap. I've lost countless hours of work due to the material browser. Now I have had to get in the habit of saving every time I venture to the material browser. Not even sure why this is a thing.

Sometimes it can happen that an old bug keeps happening, where a Standard material and Standard assets are duplicated thousands of times: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/File-performance-p...
Maybe this helps to solve the slow Material browser.

Ok, this worked. unchecking the hardware acceleration box.

I wonder what i would be missing out on by unchecking hardware acceleration.  this seem to be the only thing that fixed my issue.  It was taking about 5 minutes to cycle through materials.  I thought I had corrupted materials and it was taking me for ever to delete them all 1by1... (is there a way to delete more at a time?) anyways, this fixed it but now i wonder what i asked and underlined above. 

thank you

Slow graphic performance as Revit relies soly on CPU, not GPU.

It seems like my NVDIA GE Force 3070 is not compatible with REVIT24 ?

as of June 2024, Revit 2025, problem not solved.

Turning off the Hardware Accelerator fixed the problem for one of my users today. That some Graphics Cards are just not up to the task of Revit Materials it seems.

Autodesk in a nutshell is having the Hardware Accelerator slow down performance...

Purging materials worked for me too. I only checked everything to do with materials. after press ok I needed to do it another few times until no more materials show up to be purged. then material browser and paint tool pop up instantly. Life saver!

Thank you!

Its just a normal thing for Revit, i feel that the material browser gets slower every year, it's just said.

Turning off hardware acceleration doesn't help and makes Revit unusable.

Everything is working fast more or less, but this materials browser is retarded, to wait more than a minute to open up.
