This results in sharper, more stable shadows that better connect to the object casting them (with less acne/peter-panning). This is a demanding setting compared to `/smsize 14`, but modern high-end GPUs can still render the game smoothly with `/smsize 15` in most maps. Still, given how demanding this setting is, it's intentionally not exposed in the graphics options menu.

/smsize 14, but modern high-end GPUs1 can still render the game smoothly with/smsize 15in most maps. Still, given how demanding this setting is, it's intentionally not exposed in the graphics options menu.I also tried exposing
/smsize 16for fun, but it looks the same as/smsize 15– presumably because GPUs don't support such large textures in the first place. (I'm surprised/smsize 15even works here…; I remember when smoothly using/smsize 14was just a pipe dream.)Footnotes
Roughly RTX 3080 level in terms of rasterization performance or better. ↩
