I got a Dell 7577 laptop that i undervolted,I realised my fps drops down to 5-10 for a real long time then gets back up to 60-70 in games like Warzone, I monitored my cpu and learned that when i get a huge drop the voltages that goes to cpu drop to real low numbers and cpu clock sets 800-799Mhz, get red POWER text in throttlestop as well i got a i 7 7700HQ, here are the settings i use. I am not a competitive gamer all i need is 60-50 FPS in best optimal ways with significantly less and shorter(time) fps drops
