Big problem with my fps since the 20w22a

Since the 20w22a, my minecraft doesn't stop spinning at 5fps max.

Before the snapshot:
my minecraft (before the snapshot) was running around 50-60 FPS sometimes at 80

Since the snapshot:
My minecraft is running at 5-2 FPS.

which I guess is the problem:
since 20w22a, mojang replaced the old rendering system with a new experimental one, and they said that PCs with old graphics cards would have problems. So it might have something to do with that.

Intel HD graphics (integrated)
