Same problem here, the problem don't come from the ressource pack, because everyone have the same issue with all pack.
When i disable the ressource pack's font with optifine (or if the pack have no custom font) i have the same issue.
However ! If i load a ressource pack with custom i have no problem.
This issue comes only when the pack have no custom font.
Why this post is already lock _ ?
This bug is not resolved.
In 1.8 i have 600 fps,and this is a void world with the same render distance :o ! (EXTREM 32 chunk)
And my fps don't drop to 42 in 5 min.
