I’ve started using Blender not a long time ago, and this is one of my first projects. As a newbie, I’m probably doing something wrong with the render options. So I was rendering 1 frame per 2 mins, and I managed to render 100 frames yesterday, until I came across this error - “CUDA error at cuCtxCreate: Illegal address” and I wasn’t able to render anymore, so I had to change some render settings. I managed to fix the problem, but now the rendering takes way too long.
I’m rendering with GPU only, before the error I was using both CPU and GPU, but now it doesn’t seem to be as fast as it used to be.
The render slows down a lot when getting closer to the finish.
Same render, but this one is when I took the pic way earlier, it says it will be finished in 2 mins, but when waiting longer, the render time goes all the way to ~12 minutes per frame…
Notes: I must keep the 1920x1080 resolution. I’ve been playing around with rendering settings, turned volumetrics off, ambient occlusion too, I’ve baked everything including animations. Found the sweet spot for the tile size (256), but it isn’t enough. I lowered the subdivisions in “Simplify” tab to 2, decreased rendering samples to 64. I’m double sure that I’m using CUDA with GPU only selected, and also the GPU compute option selected.
What I might be suspicious of, is my denoiser in the “Compositing” workspace, I’ve seen on the internet that it helps to speed the rendering up and also removes all of the noise, but then also that CUDA error appeared after I added it and rendered 100 frames, but it might be a problem with my scene only, I don’t really know anymore.
- Processor - Intel® Core™ i7-9750H CPU @ 2.60GHz 260GHz;
- RAM - 8.00 GB;
- The program is installed on SSD disc;
- Windows 10 Home 64 bit (version 1809);
- GPU - NVIDIA GeForce GTX 1650 4 GB.
Any suggestions are welcome, because this animation is around ~800 frames, and later on I will have to film the scene from different angles, and I’m nearing to my deadline.
