We compute Lüscher corrections to the effective string tension in the Pilch-Warner background, holographically dual to N = 2* supersymmetric Yang-Mills theory. The same quantity can be calculated directly from field theory by solving the localization matrix model at large-N. We find complete agreement between the field-theory predictions and explicit string-theory calculation at strong coupling.
