Upgraded my RAM today to 12GB still ONI couldn't cap my monitor refresh rate in Oxygen Not Included Posted December 28, 2019 · Edited December 28, 2019 by Calvin Valerian Quote 1. Whats the bug here? I did components upgrades to see if this method will increase my FPS when rendering map with a large base. I was still trying to figure out what went wrong and who did that. Quote 3. The RAM is not your real issue. Your CPU is an old one from 2011, Ivy Bridge generation. Compared to CPUs nowadays, its a toaster. What CPU you might think suitable for me? Quote 4- Dont rely on Windows-Status-Display when it comes to CPU-usage. You´ll never come to a real 100% usage in fact, even if Windows tells you it does. (Your CPU-Cooler would burn if it was on 100% all cores...) I've once reached 100% CPU usage with older CPUs and with every CPU upgrades the more and more harder to find one, but... doesn't mean low CPU usage is bad; if I can get the FPS I deserve (76Hz) for how expensive I bought my IPS LCD monitor for; like 50% CPU usage and 99% GPU usage, THAT IS PERFECT. Why? Because I've been tinkering around with computer parts to see how video games perform in older & newer computer hardwares. But in my case I'm seeing: 44% Utilisation of CPU 23% Utilisation 2.1/6.0GB of Dedicated GPU Memory used (GTX 1060 6GB) 33-44 FPS while fully zoomed out (cycle 1933) I definitely know there's something wrong going on. So what happen to the CPU? Why the CPU doesn't wanna tell the GPU to generate more fps while there's still a fat 4.9GB of unused Dedicated GPU Memory.
