Hi, have built a PC and am of ner 1050ti on a RX 580 8gb converted. But I have almost the same amount of fps as with the 1050ti. Actually, it should be a little more with the RX 580 right? What could be the reason? In the task manager CPU and GPU are at 50% load, tested with Minecraft. Even RAM or other is only minimally utilized. Need help quickly…

Then your CPU is at its maximum.

Grade of Minecraft, the graphics card is secondary

Maybe also software problem or similar.
