Modern Warfare 4 PC Beta Performance Guide for Max FPS and Ray Tracing

What This Modern Warfare 4 PC Performance Guide Does for You

Modern Warfare 4 PC beta performance optimization is the process of matching your hardware to the official specs, then tuning graphics, upscaling, and ray tracing settings so you get the highest possible frame rate without sacrificing visual clarity or competitive visibility across different maps and modes. If you’re the friend everyone asks “why does my game stutter?”, this guide is for you. The only real prerequisite is an SSD and a reasonably modern CPU/GPU that meet the beta’s minimum requirements; beyond that, the gains come from smart settings, not magic. We’ll walk through hardware tiers, the best competitive-focused graphics options, and how to experiment with DLSS 4.5 ray reconstruction in the beta so you can push ray tracing while keeping FPS high.

Know Your Modern Warfare 4 PC Specs Before You Touch Settings

Before you chase ray tracing and DLSS tweaks, make sure your PC lines up with the Modern Warfare 4 PC specs the beta expects. The open beta uses three tiers—minimum, balanced, and performance—so older and newer builds both have a clear target. Minimum spec asks for Windows 10 64-bit, an AMD Ryzen 5 1600 or Intel Core i5-8400, 12GB RAM, and GPUs like Radeon RX 470, GeForce GTX 970/1060, or Intel Arc A580 with at least 3GB of video memory, plus 50GB on an SSD. Recommended spec steps up to Windows 11 64-bit, Ryzen 5 3600 or Core i7-8700, 16GB RAM, and cards such as RX 6700 XT, RTX 3060 Ti, or Intel Arc B580 with 8GB VRAM, again on an SSD. One quotable summary from the official chart is that "Infinity Ward has kept the requirements for the PC port quite normal" compared to many current AAA games.

If you sit near the minimum tier, aim for smooth performance at 1080p and prioritize visibility over eye candy. On balanced or performance hardware, you can push higher refresh rates and experiment with ray tracing. Either way, an SSD is not optional for the beta and helps reduce loading delays and streaming issues during matches. Think of these specs as the envelope: graphics settings optimization will help you stay comfortably inside it without random frame drops.

Step-by-Step: Beta Graphics Settings Optimization and DLSS 4.5 Setup

Here’s the practical walk-through, like I’d give you on voice chat. We’ll start with core display and quality tweaks aimed at 1080p and GPUs around an RTX 3060 Ti, then fold in the DLSS 4.5 ray reconstruction preset that’s available in the beta on compatible NVIDIA RTX cards. The big idea is simple: cut latency and heavy effects, keep clarity high, then use upscaling and ray reconstruction to make ray-traced scenes sharp instead of smeared.

1. Confirm your PC meets at least the beta’s minimum specs (Windows 10 64-bit, Ryzen 5 1600/i5-8400, 12GB RAM, and a GTX 970/1060-class or equivalent GPU with 3GB VRAM on an SSD).
2. In the game’s Display settings, set Fullscreen Exclusive, highest available refresh rate, your monitor’s native 1920×1080 resolution, and turn Background Shader Preloading On and NVIDIA Reflex Low Latency On.
3. Disable V-Sync for Gameplay (leave Menus as you prefer), set a Custom frame rate limit that matches or slightly under your monitor’s refresh, and keep Pause Game Rendering Off for consistent frame times.
4. Switch Graphic Preset to Custom, keep Render Resolution at 100%, turn Dynamic Resolution Off, choose NVIDIA DLSS as Upscaling, set DLSS Preset to Ultra Performance, and DLSS Sharpness around 50–60 for clear visuals at high FPS.
5. Turn off ray tracing reflections, motion blur (world and weapon), and weapon depth of field; leave world depth of field On if you like a bit of background separation but avoid anything that smears edges in gunfights.
6. Lower heavy settings first: set Particle Resolution, Shader Quality, Shadow Quality, and Volumetric Quality to Very Low or Low, and disable Screen Space Shadows, Occlusion and Screen Space Lighting, and Screen Space Reflections to reduce GPU load.
7. Adjust Texture Resolution to Normal on GPUs with 8GB or more VRAM, or Low on cards with 4GB or less, and use Low to Normal anisotropic filtering for sharp surfaces without much performance cost.
8. Set VRAM Scale Target to around 80% so the game does not fully saturate your GPU memory, and keep On-demand Texture Streaming and Local Texture Streaming Quality at optimized/low to avoid streaming hitches.
9. If you have an NVIDIA RTX GPU and want to experiment with DLSS 4.5 ray reconstruction, download the Modern Warfare 4 beta to get the DLSS 310.7.128 files, copy the nvngx_dlssd.dll from that package, open NVIDIA Profile Inspector, select the Modern Warfare 4 game profile, find "05 – Upscaling and Frame Generation," then set "DLSS-RR – Forced Preset Letter" to Preset F and apply the profile.
10. Launch the game, let shader preloading complete fully on the main menu before joining matches, then play a few games and review performance and clarity—DLSS 4.5 Ray Reconstruction Preset F should make ray-traced scenes look noticeably sharper compared to older DLSS 4 implementations.

The gotcha here is impatience. If you skip shader preloading or crank up textures and effects beyond what your VRAM can handle, you’ll see stutters and streaming artifacts even with strong hardware. On the DLSS side, remember this is a leaked implementation: you cannot enable DLSS 4.5 Ray Reconstruction through the standard NVIDIA app yet, and only games that already speak DLSS ray reconstruction will respond to Preset F. According to John from a PC-focused outlet, "NVIDIA has stated that it will officially release DLSS 4.5 Ray Reconstruction in August," so treat this as a beta experiment, not a permanent setup.

Why These Settings Boost FPS Without Killing Visibility

Competitive play lives and dies on clarity: seeing an enemy one frame sooner matters more than fancy puddle reflections. The beta graphics settings optimization above is built around that idea. Using DLSS Ultra Performance at 1080p lets you run higher frame rates while keeping edges and silhouettes readable, especially when you add some sharpness. Turning off V-Sync in gameplay removes input latency, while NVIDIA Reflex Low Latency cuts down on GPU and CPU queue delays so shots feel snappier. Disabling ray tracing, motion blur, and most depth of field cleans up the image: there’s less visual clutter, and the game stops smearing motion that can hide sprinting players or recoil patterns.

The biggest performance wins come from shadows, volumetrics, and complex particles. Shadow Quality, Volumetric Quality, Screen Space Shadows, and Screen Space Reflections are heavy on both GPU time and VRAM; lowering or disabling them can free up a large chunk of resources for raw FPS. In contrast, Texture Resolution has a smaller effect on FPS but uses more VRAM, which is why Normal textures are fine on 8GB cards while 4GB cards should drop to Low. Texture filtering is the helpful exception: keeping anisotropic filtering at Normal or High makes surfaces look sharper with relatively minor performance impact. On top of that, Background Shader Preloading in the beta helps prepare shaders for lighting, shadows, and effects up front, cutting down stutters and frame-time spikes when matches get chaotic.

DLSS 4.5 Ray Reconstruction, Shader Preloading, and Final Takeaways

DLSS 4.5 Ray Reconstruction is the fun extra for NVIDIA RTX owners: the beta’s leaked 310.7.128 package plus Profile Inspector gives you access to Preset F, which focuses on sharpening ray-traced content. In practice, scenes that looked blurry with older DLSS 4 ray reconstruction become sharper and more readable, which is ideal in a shooter where you still want reflections and global illumination without sacrificing target clarity. Remember that you cannot toggle this from the usual NVIDIA app yet, and not all games support 4.5 ray reconstruction; Modern Warfare 4’s beta is mainly your source for the DLLs, and other compatible titles like Cyberpunk 2077 and Alan Wake 2 have already shown how much sharper Preset F can be.

On the stability side, the beta’s shader preloading system and the way it handles shader compilation on Steam and Battle.net are small but important fixes for long-standing PC performance headaches. Letting preloading finish before matches reduces random hitching when the game first encounters certain effects. Viewed as a whole, the Modern Warfare 4 PC beta performance guide boils down to this: respect the official specs, trim the heavy eye candy, lean on DLSS and Reflex, and use ray reconstruction where it adds clarity instead of blur. It takes a bit of menu time, but once you do it, the game feels smoother, sharper, and far more reliable in the moments where wins and losses are decided.
