In the wake of Windows Vista’s rocky launch, Windows 7 emerged in 2009, garnering a wave of positive reviews that have endured for nearly two decades. Its reputation as one of the most cherished versions of Windows remains intact. However, the question arises: how does this venerable operating system perform on contemporary hardware? To explore this, we installed Windows 7 on a modern PC and conducted a performance evaluation across eight DirectX 11 games and two DirectX 9 titles, comparing its gaming capabilities to those of Windows 11.
Performance Testing
Our testing encompassed ten games: eight utilizing DirectX 11 and two based on DirectX 9. The focus primarily rested on the DirectX 11 titles, as both operating systems support them natively. Windows 11 manages DirectX 9 games through the D3D9On12 mapping layer, while Windows 7 runs them natively. Although there are workarounds for Windows 11, we aimed to assess the out-of-the-box experience for most gamers, anticipating an advantage for Windows 7 in the DirectX 9 titles.
The performance advantages of each operating system varied depending on whether the system was CPU-limited or GPU-limited.
Metro 2033 Redux (DX11)
Metro 2033 Redux, released in 2014, showcases a sophisticated lighting engine and enhanced visual fidelity. While the game is predominantly GPU-bound, there are moments when GPU utilization dips, leading to CPU limitations and a corresponding performance drop.
Interestingly, while Windows 11 achieves a higher average frame rate, Windows 7 demonstrates superior handling of CPU-related performance drops, resulting in significantly stronger 1% lows. The installation of AMD chipset drivers and enabling Resizable BAR slightly improves 1% lows on Windows 11, yet it still lags behind Windows 7. The advanced graphics driver in Windows 11 provides an edge in GPU-limited scenarios, while Windows 7’s lower CPU overhead ensures more consistent frame pacing, albeit with lower peak performance.
Batman: Arkham Origins (DX11)
Running on a modified version of Unreal Engine 3, Batman: Arkham Origins utilizes several DX11 enhancements, including tessellation and ambient occlusion. In our tests, Windows 7 outperformed Windows 11 in both average frame rate and 1% lows at 1080p, even extending its lead at 4K, albeit with a smaller margin. This trend, however, is not consistent across all titles.
Batman: Arkham Knight (DX11)
Despite a troubled launch, Batman: Arkham Knight remains visually impressive, and modern hardware can easily handle its demands. At 1080p, Windows 7 again shows higher performance when CPU-limited, while Windows 11 takes the lead in GPU-limited scenarios at 1440p and 4K.
Batman: Arkham City (DX11)
This sequel introduced DirectX 11 support, enhancing geometric detail through tessellation. Our testing revealed that Windows 11 held the advantage across all resolutions, as the system was GPU-bound throughout.
The Witcher 3: Wild Hunt (DX11)
Initially controversial for its image quality, The Witcher 3 quickly addressed concerns with patches that improved visuals. Despite being GPU-bound, Windows 7 managed to outperform Windows 11 in 1% lows at 1080p, while Windows 11 took the lead at higher resolutions.
Control (DX11)
The latest title in our comparison, Control, launched in 2019 and remains graphically advanced. As expected, Windows 11 outperformed Windows 7 across all tested resolutions due to its GPU-centric optimizations.
Hitman: Absolution (DX11)
Utilizing the Glacier 2 engine, Hitman: Absolution was groundbreaking at its release. Our tests confirmed that Windows 11 maintained a performance edge, particularly as the system was GPU-limited at all resolutions.
Batman: Arkham Asylum (DX9)
As our first DirectX 9 game, Windows 7 demonstrated significant advantages in average frame rate and 1% lows, especially at lower resolutions. The performance gap narrowed at 4K, yet Windows 7 continued to deliver smoother overall performance.
Borderlands 2 (DX9)
In our final test, Borderlands 2 reaffirmed Windows 7’s dominance at lower resolutions, with performance at 4K being nearly identical across both operating systems.
Windows 11 is Optimized for GPU-Hungry Games
The results of our testing reveal a nuanced landscape. While Windows 7 excels in CPU-limited scenarios, Windows 11 shines in GPU-bound situations, thanks to its advanced graphics drivers. Microsoft’s ongoing K2 plan aims to enhance Windows 11’s performance and reliability, and we hope these efforts yield improvements. The lower CPU performance observed in Windows 11 cannot be solely attributed to its security features, as we disabled them during testing. Ultimately, a leaner and more efficient Windows 11 could unlock further performance potential, particularly on the CPU side.
