Call of Duty: Modern Warfare 4 gets DLSS 4.5 at launch
Day-one DLSS 4.5 for RTX 50-series owners
NVIDIA dropped a Game Ready Driver for Call of Duty: Modern Warfare 4's October 23 launch, adding DLSS 4.5 support alongside Advanced Shader Delivery. Campaign Early Access opened October 16; DMZ followed October 20. Multiplayer arrives when the full game ships.
DLSS 4.5 is NVIDIA's latest upscaler iteration (Blackwell architecture, RTX 50-series). Cyberpunk 2077 also got DLSS 4.5 in this driver update, along with Crimson Desert Enhanced: Charting the Unknown and Phantom Blade Zero. No frame-rate claims or comparison data in the press release — you'll need to benchmark your own rig to see how the new upscaler stacks against DLSS 4.
This is a day-one feature for MW4, not a post-launch patch. If you grabbed Early Access and your RTX card supports DLSS 4.5, the driver's live now. Anyone on RTX 40-series or older stays on DLSS 3.
Run a fresh MW4 playbook to lock settings for launch day — BetterFPS will update targets once multiplayer drops and the benchmark crowd posts real numbers.
