Will upgrading to 32GB of RAM fix game stuttering?

Yes, if the stuttering is caused by running out of memory. Open-world games with huge textures can easily eat 16GB, and when RAM fills up, swapping to your SSD causes micro-stutters. But 32GB won’t fix stutters from a weak CPU, poor optimization, or a GPU bottleneck. Check your task manager — if memory usage is near 100% during stutters, 32GB helps; if under 80%, look elsewhere first.
