I have an i5 9600k and an rx 6600 xt, but my pc performs slowly and not up to the standard ive seen performing on benchmarks of identical systems. ( i see some benchmarks saying 70 fps on cyberpunk high, while mine struggles to pull 60 on low sometimes. ) it isnt a cooling issue as i have 6 case fans , good airflow and a water cooler on my cpu, is there anything i can do to find out why it performs poorly ?
