Recently, I noticed that when I play minecraft, in any version, the render distance is seemingly stuck to a max of 16. It can go lower than this but 16 is the highest even with optifine. I tried re downloading and deleting java and minecraft, and deleting all mods and all everything to due with minecraft. I even updated drivers and did a security check and everything else under the sun. If anyone has got any ideas, they are much appreciated. Thanks.
Im playing in 1.14.4 and the whole problem started I think possibly when I increased my allocated RAM from 5GB to 5.5GB. Even though I knew I don't need that much, I did anyways. I now have changed it back to 4GB or even 2GB and did everything else i mentioned, but the problem is still here. It kinda happened randomly and very serious chunk loading lag came with the problem as well. Its basically unplayable now.
