Minecraft doesn't use all of my computer's resources.
I observe 0 fps when using 11.16% of RAM and 31.3% of CPU resources. Please tell me how to increase the allocated RAM and increase fps. JVM arguments do not produce results.
Minecraft использует не все ресурсы компьютера.
Наблюдаю 0 fps при использовании 11.16% оперативной памяти и 31.3% ресурсов процессора. Подскажите, пожалуйста, как увеличить выделенную оперативную память и повысить fps. JVM-аргументы не дают результата.
33% CPU usage could actually be 100% usage of a single core on your CPU - make sure that it's actually using your GPU to render. Don't ask me how, I don't know how that works, just search online and I'm sure you'll find an answer.

turning on all cores != a program using all cores. Each process thread can only run under a single core, and Minecraft (and any other OpenGL application) only has a single render thread - which is the same thread as the client tick (for good reasons). Minecraft is programmed to prioritize client ticks over render ticks, so if running at 20 client ticks per second maxes the thread, your FPS will be 0.
Regardless, a 3.3 GHz CPU should be enough, so I highly doubt that's the issue.
