Direwolf20 lays despite enough specs?

I play the modpack direwolf20 in minecraft and it lays despite 8gb ram, a ryzen 5 2500u and vega 8.

what can I do except the graphics settings anyway at the minimum?

have just under 3 fps

I know your problem: / It could be that you have not allocated enough RAM to Minecraft yet. If you do not know how to allocate RAM, then contact me!
