Quote - 1) Impatient and don't care about quality. These people insist on using DMS for speed and we make fun of them.
2) Impatient but want better quality. These people use RTS but they disable "visible in raytracing" on the hair, so it doesn't slow things down. Then they add hair shadows in postwork, or they just don't bother and we make fun of them.
3) Patient and demanding high quality. These people use RTS and make everything have shadows, no matter that it takes 40 minutes to render.

4. Animators. These people don't know what to use and we pity them.

I'm number two. If it only took 40 minutes to render hair with 'visible in raytracing' ticked, I'd leave it on. If it only took 1hr 40 mins, I'd leave it ticked. In my case, the difference is multiple hours. I have a fairly OLD PC...
