I have an Alienware M17 (laptop) with specs:
i7 8750H, RTX 2070 Max-Q (set as preferred for the game), Intel UHD 630, 16GB RAM, BIOS 256GB SSD, Main 1TB Hybrid Drive and Killer AC Wireless 1550
I looked into required specs to run Warzone and it said I only would need an i5 2nd Gen and GTX 970
My PC is actually well above the specifications listed there however the CPU clocked up to 100% dropping from 3.9Ghz to 3Ghz
I did alter some settings in the Nvidia Control Panel below:
Altered background app frame rate to 200Fps
Low Latency Mode on Ultra
Max Fps to 1000Fps
OpenGl Rendering set to the RTX 2070 Max-Q
Power Management set to Consistent Performance
Threaded Optimisation set to ON
Triple Buffering set to ON
If any of this alters how Warzone runs please do tell how
