I have the following system:
Windows 10 (current version)
64 GB RAM
i9-9900ks
2080 Ti (EVGA Ultra FTW hybrid)
z390 AORUS Master
I spent a few hours yesterday and most of today trying to update everything and figure out what the problem is. Here is what I have done:
Updated my drivers, including reinstalling some relevant drivers entirely
Updated BIOS
Disabled integrated graphics
Tried every single render option in Blender, including combinations
Reset Blender to factory settings
Reinstalled Blender
Tried a new project file
Nothing works. Every time I animate something, Blender slows to about 1 fps. It never uses my GPU at all, and it only uses up to about 50% of my CPU (it was only about a third until I did everything above). My GPU runs perfectly in every other program, and I even left a benchmark running for 5 minutes maxing it out the entire time and did normal on it.
Does the problem only occur with 2.82a? Did this work with previous versions?
For Windows, people recommend downloading the nvidia driver from the official site and doing a clean install (I don’t remember exactly the name of that option in the nvidia installer).
You share here screenshots of how you have GPU related options configured in Blender, and a simple .blend file where you can reproduce the problem.
Hi, do you meant you animate in preview render mode?
Have you change to GPU in render settings?
Is CUDA checked in user preferences > system?
Cycles is not a real time render engine, it need sometimes 10 minutes per frame (or hours). You can use EEVEE render engine for it, nearly.
I have tried every option, but it is always slow in the animations option. I have changed everything I can, and I see that it does use my GPU, but only about 20%, and it only uses about a third of my CPU. After talking to some others that make models, they also see that it only uses about that much of their completely different system.
I have tried them all, but I now leave it on CUDA with my GPU selected. I just started modeling with blender a week ago. I have nearly finished my first two models, though!
You should clarify what you mean by animation and which engine you are using.
If you mean render animation (“Render” menu > “Render Animation”). Or if you refer to Viewport Play Animation preview from timeline.
In any case, you will get better support if you show screenshots of your settings or if you share a problematic .blend file here. Many issues related to slowness have to do with how optimized or heavy the scene is.
