Minecraft Performance Problems with Ryzen?

Since today for an inexplicable reason have an extremely low GPU utilization at Minecraft?

Minecraft is CPU-heavy, as long as you do not have a shader installed, your GPU has nothing to do either.

Trzdm should you have more at such a high rate

've also currently installed the sildurs shader mod

I have not run Minecraft for ages, but even if I look at your picture, Minecraft is still a single-core process, you only use the 16th core, as you can see. And besides, Minecraft is poorly optimized and jerky like no idea what.
