Hi everyone!
As the title suggests I need help optimizing blender to be the fastest possible. I set my preferences to use optix for the gpu only (both gpu/cpu options pop up) as well as the viewport/render denoise is set to optix.
However, I am not sure if I am missing a step here as I noticed whenever I change materials to my daz character and hit render preview button blender constantly loads “render kernels” and takes quite a bit to load the setup… once that’s done though it is quite fast to go from textured view to render preview using optix but how do I speed up that beginning kernel stage?
Thanks for any tips!
Blender is already a optimized software but there’s some adjustments that can increase performance:
Blender Preferences > Viewport > Viewport Anti-Aliasing > No Anti-Aliasing
Use CPU + GPU option, tile size set to 256x256. I prefer CUDA but I think Optix need some test renders.
Render with Adaptative Sampling and use compositor Denoiser.
Disable all addons, and start to turning on as needed.
Keep in mind that an enabled modifier is computinal heavier than an applied one.
That BVH built before each render is mostly liked to be affected by memory frequency, don’t know for sure.
Yet I think with that setup you can just play around without think about all those minors improvements. If you’re going to manage big scenes, it’s more efficient to think about model, texture and sampling optimization.
