System Information
Operating system: Win 10
Graphics card: NVIDIA GeForce GTX 1050 Ti

Blender Version
Broken: 3.6.0

Short description of error

I have some problems while opening a file. For a long time Blender wouldn't let me open it because there was a command "program is not responding". Now, after the same command, Blender manages to open, however it works very slowly and is laggy. I don't know if that's helpful, but after opening a file, my memory goes up to 98% in Device Manager. tried to follow this thread: #86778, and update drivers, but it doesn't solve anything. Please help.

This could help further with the system-info file, that is available from the Blender menu:

Help > Save System Info

Also, an error causing version of your blender file could help the troubleshooting. It could also matter which version of Blender the file was created in.

Hey, thank you for a reply! Here's system info. I don't really know what you mean by "an error causing version of your blender file". You want more specific details? Screenshots? Files?

The file was created in the same verion of Blender I stated in my report. I started using Blender several days ago.

Meaning, any .blend file that you are using that causes the problem to occur on your computer. If you can upload it, this will also help the troubleshooters further.

Also try these steps, just to get them out of the way:

File > Defaults > Load Factory Settings
and if that doesn't help
Run the script file blender_factory_startup.cmd that resides in your Blender installation folder
Apparently, there are some addons that can cause issues that the above steps can help resolve.

Oh sorry, I could swear I attached .blend file to my report, but for some reason it's not there, here you are.

EDIT: Oh now I know why, file is too big. I'm sending this via wetransfer, hope you don't mind. https://we.tl/t-QArF4XIKuA

This is a huge file, almost 900 MB. And it takes up more than 20 GB of RAM just to open it.

To the extent of my limited knowledge of Blender, unless the computer has at least 32 GB of RAM, with a GPU that has at least 8 GB of VRAM, using this file will be panifully laggy in Blender, and that is if you are running only Blender on the computer. If you want to run more programs with Blender with this file, then 64 GB of RAM would be better.

To open this file without freezing/lagging, Blender needs a more powerful computer than what you have, or Blender needs this file to be simplified. For example, the mesh is using more than 13 Million triangles. If you are learning Blender, you don't need such a dense mesh to practice, unless that is the requirement for your course.

If you don't specifically need the density as a requirement for your workflow, you can use the decimate modifier on the mesh. For the GTX 1050 TI, I would use Decimate > Collapse at a ratio below 0.5. This would be less than half the density of the current mesh, and would at the least make your Blender experience much less laggy, if not smooth. It will still take time to open it, but not as much as before. And depending on how much available RAM you have, you may still experience some intermittent freezing.

Thank you so much, it helped! Although you worried me, because I would never suspect Blender to be THAT demanding. I barely started working and the file is already that huge.

Do you have any more advises how to make my work more bearable to my computer? I'm scared similar situation might occur in the future.

I am glad it helped.

Watch your mesh density and your computer will be responsive.
