Minecraft shader makes FPS extremely down?

I have the problem that when I install a shader and then I turn it on, it pulls my FPS down quite a bit into the 20, 30 range. Sometimes the shader is then also different than it is in the pictures. It can't be because of the graphics card because I have an RX 6900 XT. Can someone help me.

Maybe it's your processor?

That is an I7 9700K. And that is only used up to 11%.

Hmm, the RAM? Otherwise I have no idea…

I assigned 6Gb RAM should be enough, right?

Yeah, I meant the speed more. If nothing else helps, try setting the priority to real time in the task manager.

The ddr4 RAM with 3200MHz

Ok, then it's not there either. Right-click on Java in the task manager, switch to details, then right-click again in details and set the priority to real-time. With your system you don't have to worry, nothing happens, even if there's a warning. This is only for 1-core systems.

Depending on the shader, this is normal. For me (9700K and 3070), the fps are sometimes so low.

Thank you for your help. But it wasn't because I had this FPS limit in the Minecraft setting on off or so that there was then V-sync. When I did that at 145 fps it worked again.

Ok I'm pleased.
