They care even more, they just use less snake oil these days, as the experimentation is much more precise than before. The main focus for today's competitive players is not throughput, but motion-to-photon latency and its consistency (consistent frame times, constant input lag). Both improved greatly in recent years from thoughtful tweaks such as limiting your FPS to avoid GPU queue congestions, and due to software developers finally paying attention (NVidia and AMD introduced several low-latency tricks into their drivers, Microsoft also did lots of scheduling-related work). Hardware also got substantially better with latency.
