Describe the bug
fps without mods and texture packs does not exceed 40fps at medium graphics settings. When i install the Bare Bones texture pack, the fps is kept at 20 frames. compared to rethinking voxels beta (or seus renewed) that have an average of 90fps it's not so stable. dedicated memory for java 4gb.
I would like to know if this is a problem with Optifine or the shaders themselves?

Expected behavior
stable fps at least 60-90 fps

Desktop (please complete the following information):

• nvidia rtx2060
• Intel core i7-10700
• ram 16gb
• OptiFine 1.19.2_HD_U_I1

OptiFine HD U I1

Additional context
Sun and moon looks way too big and bright, especially at night. it would look more natural if the shape of the sun repeated the original shape from minecraft and did not overlap the texture.

Hello, could you provide your Optifine settings, shader settings, and F3 screen for more additional info?
