Hello! To understand visually. Nominally mats V-Ray has 8 subdivs. As a rule, it is enough for the majority of glossy effects . If, on the material appears, obviously the noise, then the effect is calculated with sufficient accuracy and necessary to increase the number of Subdivs effect. This occurs most often with Reflection glossiness. Sometimes, there is even a relevant value in the 30-40 Subdivs. But this is an extremely rare situation. As for Refraction glossiness, the more likely the other way around, nominal value set in the Subdivs 8, even more than is required, and to increase the speed of rendering refractive materials, it is possible to reduce this value to 6i and even up to 3 Subdivs😉
