cpu amd 4300 quad core
gpu radeon RX 460
8 gb ram
os windows 7 64 bit
java is up to date drivers are up to date and all that jazz
the issue is in some minecraft 1.10+ modpacks i get 60+ frames but in most of them i get 1-2 frames and i always dedicate the suggested amount of ram like in the new dw20 pack for 1.12 i get 60 but if i try the new sky factory or any other 1.12 1.11 or 1.10 packs i get 1 fps so i was just curious if anyone could give me any suggestions to try i have tried posting in other threads and i have done hours of research to no avail so anything is appreciated.
