Yes it did reduee my render time a lot. However, as noted in this video, my animation is not smooth.
Not so important to me. I expect people to stop the video and watch the stills.
My settings are:
Render samples: 16,
Denoiser is NVM.
16 is smooth especially the edges. 8 distorts the surface. 4 is clean but distortion is obvious.
For viewing, I use 1 sample only.
Tile size was 128. 256 slows down all my graphic cards, GTX1650X, GTX860M, and QUADRO K2100M.
The transmissions, leave it to 12 until a PC breaks down. My most expensive laptop, the Lenovo Y50-70 crashes a lot, and had to resort to lowering the Lightpaths\Maximum bounces to 8 etc. Then render samples to even 4. Even the Cautics.
The Caustics affect my Transparent Car a lot. If I disabled both, I cannot see inside the transparent skin of the car. But when I only disabled transmission, I still can see. But sometimes, it failed also.
The best option for me is just not use this Y50-70 to render any image but use it to combine the images into a video. Y50-70 is my faster machine but handicapped by 16Gb of RAM.
My desktop PC, despite using an old AMD microprocessor, is equipped with GTX1650S, and is therefore faster in rendering.
A lot of rendering software uses NVIDIA graphic cards. Even MicroCFD uses CUDA, which is why it is not advisable to buy AMD graphics cards.
