Yes. Call of Duty: World at War (2008) requires a dedicated GPU for any playable experience. Integrated graphics of that era (Intel GMA 950, X3100) cannot run it.
Any discrete GPU from 2012+ (GT 630, HD 7450, Intel Iris Xe, UHD 630) runs it at 1080p/60 High. Even a $50 used GTX 750 Ti crushes it.
Verdict: Dedicated graphics card mandatory. Check Can You Run It for your exact hardware.
