Does 32GB RAM reduce stuttering in Cyberpunk 2077?

Yes. At max settings with ray tracing, Cyberpunk can use 18–22 GB of RAM, so 16 GB causes Windows to swap to your SSD, creating microstutters. 32 GB keeps everything in RAM, eliminating those memory-related hitches. However, stuttering from a maxed-out GPU or CPU won’t be fixed by more RAM.
