Author Topic: Substance Painter 2021 | Slow and lag with 8K designer materials  (Read 70 times)


The painter is running extremely slow and laggy after importing designer made 8k material. Just changing the offset to even 0.001 takes atleast 15 minutes to move the texture which makes it impossible to work on.

I have upgraded the workstation to be able to work on 4k/8k materials and textures but it has been extremely slow.

I would like to know if I can change any setting in the software (increase cache etc) to speed up the workflow. Below are my computer specs.

PC Specs

Ryzen 7 3800x (8 core, 16 threads)
Rtx 2070 (8gb)
64GB 3200mhz
1tb SSD

Thank you.
