This is almost true. ALMOST because all people including me have 30-40% CPU utilisation MAX (looking at specific cores). There's even no 100% vram usage - i have 32GB RAM and 8GB VRAM system. AT most it utilised 3,7GB vram of 8. So 40% CPU + 50% GPU + 50%vram + 25% RAM utilized. No throtling, noc1 states, performance everywhere. It means streaming system. Thank you.
p.s. plus my 15 years of experience
