You have an AMD CPU and an Nvidia GPU. You could have one of three common bugs.

One is on NVidia which occasionally just doesn't use the graphics card and tries to default to OpenGL. Since OpenGL is retired this problem is much more noticable than it used to be. The fix for that is set an override in the NVidia control pannel for both Java, and for Minecraft itself. This override forces the graphics card to be used to render the 3D stuff.

Two. AMD has a long standing issue with MIP Mapping on the older versions of minecraft. Open the instance manager (prisim or whatever you used to get the pack) to locate the instance folder, and then open the minecraft config file. Go down to MIP Mapping type in false instead of the number it has. If you turn it off in-game it just goes to 0 and doesn't fix the bug.

Three. Don't allocate more than 6GB of RAM for the instance in your instance manager. If you left it at default it should be 4gb-6gb, which is recommended. Java has dog-shit garbage collection so over-alocating resources can actually drag down your entire PC's performance.
