Call of Duty 4: Modern Warfare GPU Requirements — Integrated vs Dedicated Graphics

You don't *strictly need* a dedicated GPU for Call of Duty 4: Modern Warfare (2007), but it's highly recommended.

Why a Dedicated GPU Matters

• Performance: Offloads rendering from CPU → smooth gameplay, higher FPS, better visuals.
• Minimum specs list a GPU: While integrated graphics *might* run it at lowest settings, experience will be poor (lag, stutter, low res).

Integrated vs. Dedicated

• Modern Integrated (Intel UHD/Iris Xe, AMD Radeon Vega/RDNA2): Can run CoD4 at 720p Low ~30-60 FPS. Playable but not great.
• Dedicated (GTX 1050 / RX 560 or better): 1080p High 60+ FPS easily. Vastly superior.

Conclusion

Technically possible on integrated graphics, but a dedicated GPU—even an older budget one—transforms the experience. For a 2007 game, any discrete card from the last decade will max it out.
