How do I stop unit lag when deploying large armored clusters in Ground Control 2?

I was deploying armored clusters when I noticed visible lag in unit turning, caused by background processes hogging 12.5-14.2GB of memory. I tried cleaning temp files, but it made no difference. I used GamePP Resource Scheduler to set the game process to Real-time priority and switched to High Performance. RivaTuner confirmed frame intervals dropped from 9.2-13.5ms to 5.8-6.9ms, and AIDA64 showed memory temps stable at 55-60℃. This saved my immersion.
