Same world, same location but different version. About 250 FPS with 1.7.4 and 60 FPS with the latest snapshot.
Same settings on both instances, no vsync.

Do you have VSync enabled?
VSync synchronizes the frame rate to your monitor's one, so it avoids rendering glitches. Basically if it's enabled, it means that you have a 60Hz monitor, and you really won't be able to see more than 60 FPS. I suggest you to keep it enabled, because there's no difference between what you can see when it's enabled and what you can see when it's disabled.

No, I made sure I had the same settings on both instances.

Have you tried enabling and disabling it again? Sometimes it's a bit buggy

Got little FPS drop and it's making lag spikes. Also if you noticed "Used memory" is freaking out (8Gb allocated).

I usually get the FPS drop in every snapshot. The allocated memory stays to 100MB max and my FPS are above 200 on max settings
