Hello all, so quite recently my little brother got a pre-built pc and being an entry level machine it should run Minecraft with shaders smoothly at 1080p on ‘Fast’ and render distance 8 chunks. However the game it self runs just fine but the shaders just screw up badly. (screenshot attached)https://imgur.com/a/Sq0v5tr
Anybody has a clue what could be the issue? Please help 'cuz he is driving me nuts about this -,-
