How to Get Call of Duty: Modern Warfare 4 Running at Its Best on PC

Call of Duty: Modern Warfare 4 has been out on PC since October 23, and the launch build carries over everything Infinity Ward and PC lead developer Beenox detailed in their pre-launch PC trailer and tech breakdown: three competing upscalers, a split depth-of-field system, an Enhanced FOV mode exclusive to PC, and a built-in benchmark tool meant to replace guesswork with actual numbers from your own rig. With 800+ settings spread across graphics, input and interface menus, the default auto-configuration gets most players to a playable state, but it rarely finds the fastest or clearest setup your specific GPU is capable of. Here is how to work through the menu with intent.

Check Your Hardware Against the Real Tiers

Modern Warfare 4 ships with three official hardware tiers, and knowing which one your PC falls into changes which settings are worth touching at all. The minimum tier (Radeon RX 470, GeForce GTX 970/1060 or Arc A580, 8GB RAM) is built to simply launch the game, not to hit a specific frame rate. The recommended tier (Ryzen 5 3600 or Core i7-8700K, Radeon RX 6600 XT, GeForce RTX 3060 Ti or Arc B580, 16GB RAM) is the one Infinity Ward actually tuned around, targeting 90 FPS in multiplayer on High settings. The ray tracing tier (Ryzen 7 3700X or Core i7-10700K, Radeon RX 9070 XT or GeForce RTX 5070 Ti, 32GB RAM) is what the studio recommends for High-quality ray tracing at an upscaled 4K. Every tier assumes a 115GB SSD install; Modern Warfare 4 does not have a supported path on a hard drive.

Two platform requirements are easy to miss and will block launch entirely if skipped: TPM 2.0 and Secure Boot must both be enabled for RICOCHET Anti-Cheat, and Intel Arc owners specifically need Resizable BAR turned on in their motherboard firmware. Activision keeps its own walkthrough for the TPM requirement, and it is worth confirming before you touch any in-game slider.

Pick the Upscaler That Matches Your GPU, Not the Default

The game's auto-configuration will often land on whatever upscaler is bundled for your GPU vendor, which is the right starting instinct but not always the best end state. NVIDIA RTX cards get DLSS 4.5's deep-learning frame generation and sharpening, Radeon cards get AMD's ground-up FSR Redstone, and Intel Arc owners get XeSS 3. Filmic SMAA T2X remains the default fallback anti-aliasing pass for cards that skip upscaling entirely, and it is also the cleanest option if you are running native resolution on a high-refresh monitor and don't need the frame-rate headroom.

• On RTX 30-series and newer, set the upscaler to DLSS 4.5 and leave frame generation off for multiplayer, where added latency matters more than the extra frames.
• On Radeon RX 6000-series and newer, FSR Redstone at Quality mode is the closest equivalent; test Balanced only if you are chasing a 1440p or 4K target.
• On Arc B-series cards, confirm Resizable BAR is active first, since XeSS 3 performance drops sharply without it.

Whichever upscaler you land on, the new sharpness slider is now global rather than tied to one specific technique, so it is worth re-tuning any time you switch upscalers rather than assuming your old value still applies.

Use the New Clarity Settings Instead of Just Cranking Everything Up

The PC-exclusive Enhanced FOV option is the single setting most likely to change how the game actually feels to play. It uses lens-correction math to widen your peripheral awareness near the edges of the screen without pushing out your center FOV, which is the part that normally makes a wide field of view feel distorted. Pair it with HDR10+ if your monitor supports it; the engine reads your display's real brightness in real time and adjusts contrast automatically, which is a genuine improvement over manually dragging brightness and gamma sliders until a loading screen looks right.

Depth of Field is now two separate settings rather than one. Splitting World Depth of Field from Weapon Depth of Field means you can keep the environment sharp for spotting enemies while still getting the softer, more cinematic blur on your own gun during ADS. For competitive play, turning World Depth of Field off entirely while leaving Weapon Depth of Field on is the setup most likely to help target acquisition without making your own viewmodel look flat.

Run the Benchmark Tool Before You Trust Any Preset

Rather than relying on a generic preset, Modern Warfare 4's built-in Benchmark Tool runs a simulated multiplayer sequence against your actual hardware and reports average FPS, CPU and GPU load, ping and input latency, broken down zone by zone. It then suggests specific settings to adjust for whichever zones ran worst, which is a far more useful starting point than copying a settings list built for someone else's PC. Run it once after any driver update or major settings change, since the shift from, say, a Balanced to a Quality upscaler preset can move your bottleneck from GPU-bound to CPU-bound in ways a single FPS counter won't explain on its own.

Don't Skip the Driver and Shader Steps

Activision's own recommended driver versions are AMD 26.7.1, Intel 32.0.101.8974, and NVIDIA 616.56, with an Advanced Shader Delivery-compatible NVIDIA driver meant to land around launch; installing an outdated driver is one of the more common causes of stutter that looks like a settings problem but isn't. Advanced Shader Delivery itself precompiles shaders ahead of time through the Xbox PC app, which cuts down the traversal stutter that normally shows up on a fresh install or right after a big patch. It only kicks in if the Xbox PC app is installed, even for players running the game through Steam or Battle.net, so it is worth grabbing even if you don't plan to actually launch from it.

Modern Warfare 4's PC hub and the game's Steam store page both keep their hardware and driver guidance current as Infinity Ward and Beenox patch the game, so it's worth a check back after any major update rather than assuming October's numbers hold forever.
