I'm struggling to understand why is performance so bad when I'm editing rig controls or whenever I start the animation playback. My scene is a mannequin character exported from the Unreal Engine 5. I checked the tris count and it's almost 100k which isn't really that much. Then whenever I perform any of the above mentioned actions the FPS drop to range between 12 and 15 which I consider bad.

My specs: RTX 4070 Ryzen 7 3700X

I have tried looking through different settings inside preferences but no luck there. I also tried installing different Blender versions so I tested this on Blender 3.3, 3.4 and most recent 3.5, all of them act exactly same.

Does anyone have an idea what could be happening here? Cheers for any help!

    $\begingroup$ that doesn't sound normal indeed, could you do file > external data > pack all into .blend file, then file > save as : enable compress in sidebar and save a copy of your file, then upload it somewhere like Blend-Exchange and share the link here with us so that we can dig in? $\endgroup$

  • $\begingroup$ Sure thing, file is too big for blend-exchange but I uploaded it to my mega cloud, you can download it here: mega.nz/file/… Let me know if it's all right and nothing is missing! Thanks for checking this out $\endgroup$

  • $\begingroup$ I checked the file, and I'm pretty sure there isn't any issue there. So I'd advise you to first try to make a clean reinstallation of your graphics driver, and try again. If this doesn't work, then go to the menu Help > Report A Bug and send a bug report with the pre-filled instructions, and send the file there too. Hopefully the devs will either find out what's going on, and make a fix for it if need be. $\endgroup$

  • $\begingroup$ Right, so I was afraid it might be an issue on my side. I have recently performed clean driver installation as I was switching from RTX 2070 to 4070 and figured this might be the issue. I'll report the bug. Thanks for your help! $\endgroup$
