Issues with GTA V performance.
open the windows search, type "defrag" and it should appear there. Just note that you didn't defrag your SSD. Also, adjusting your page file was something I did before my GTA ran smoothly. I set it up in advanced settings, then performance options, and finally advanced again. I usually use my SSD for the page file, choosing a size of about 1.5 times total RAM as a minimum and up to 2.5 times for maximum.
Consider reviewing a manual that walks through the configuration options and highlights the parts that strain the CPU or GPU. Check if your advanced game settings are disabled or adjusted. (Also experiment with grass settings—V-High instead of Ultra.) This approach kept GPU utilization steady around 98-100%, compared to a more fluctuating 80% before.
