We tested gaming performance in 17-year-old Windows 7 on a modern gaming PC against Windows 11

In a recent test comparing gaming performance between Windows 7 and Windows 11 on modern hardware, the results revealed notable differences. Windows 7, launched in 2009, was still widely regarded as a favorite operating system despite its age. To evaluate its performance, researchers installed Windows 7 on a modern PC and conducted tests across eight DirectX 11 games and two DirectX 9 titles.

Upon installation, Windows 7 exhibited many similarities to its predecessor, Windows Vista, including technologies like SuperFetch, ReadyBoost, and native processor power management. However, Windows 7 introduced improvements such as enhanced control over User Account Control (UAC) and better handling of hardware advancements. One significant advantage of Windows 7 was its compatibility with modern hardware, as mid-range and budget PCs often struggled with Vista's demanding features, like Windows Aero, during its launch.

When testing gaming performance on the AMD Radeon RX 6950 XT GPU with 64GB of RAM, Windows 7 surpassed Windows 11 in several aspects. Windows 7 was more adept at handling CPU-related performance drops, particularly in DirectX 11 games that were predominantly GPU-bound. In these situations, Windows 7 showcased stronger 1% lows, indicating more stable and consistent frame rates.

The test also highlighted the importance of driver support, as Windows 7 required slipstreamed drivers for NVMe and USB 3.0 support, while Windows 11 relied on the newer Adrenalin 22.6.1 driver package. Despite these differences, both operating systems performed well on DirectX 9 titles, with Windows 7 having an advantage in those scenarios.
