The release of Call of Duty: Modern Warfare is right around the corner and while it will require an insane 175GB of HDD space, the game has even loftier requirements if you want to turn on those gorgeous ray tracing effects.

NVIDIA has detailed the PC requirements to enable ray tracing in Call of Duty: Modern Warfare, with 1080p 60FPS (no ray tracing enabled) requiring a GeForce GTX 970 or GeForce GTX 1660, while ray tracing at 1080p 60FPS is going to need a GeForce RTX 2060 SUPER at a bare minimum.
If you want to bump things up to 120-144FPS on those high refresh rate gaming displays, NVIDIA recommends a GeForce GTX 1080 or newer GeForce RTX 2070 SUPER -- but if you want to step into the Big Boys Club and enabled 4K 60FPS with ray tracing enabled, NVIDIA recommends its new GeForce RTX 2080 SUPER graphics card.
Funnily enough, NVIDIA mentions the GTX 1080 in its 'High/Competitive' option, but no mention of the flagship GeForce RTX 2080 Ti and instead the highest-end option with 4K 60FPS with ray tracing enabled requires the second-fastest Turing-based GeForce in the RTX 2080 SUPER.
I would say Call of Duty: Modern Warfare is NVIDIA's last flagship RTX-enabled game of 2019, and the fastest card it recommends is the second-fastest GeForce RTX graphics card. Interesting.
Still, you're going to need a pretty beefy PC to run Call of Duty: Modern Warfare with RTX enabled -- with NVIDIA recommending you have an Intel Core i7-9700K or AMD Ryzen 7 2700X at a minimum, 16GB of RAM, and the aforementioned GeForce RTX 2080 SUPER to enjoy the game with ray tracing enabled at 4K 60FPS.
