16GB will likely fix your Warzone stutters.

Yes, upgrade to 16GB. Your 5600X and 3060 are fine for Warzone — 8GB of RAM is the bottleneck.

Warzone is a memory hog. It can easily eat 10–12GB during a match, especially with background apps. When you only have 8GB, Windows starts swapping to disk, and that micro-stutter you’re feeling is the system begging for breathing room. Go to 16GB (dual-channel, ideally 3200MHz or faster) and those stutters should vanish.

The GPU is not the problem here. The RTX 3060 handles Warzone fine at 1080p or even 1440p with some settings tweaks. If you still get stutters after the RAM upgrade, then start looking at drives (make sure it’s on an SSD) or driver settings.

RAM is cheap. Do it.
