Windows 11’s GPU scheduling can reduce VRAM by nearly 1GB on budget GPUs

Hardware-accelerated GPU scheduling (HAGS) in Windows 11, enabled by default, can reduce available VRAM on GPUs with 6GB or 8GB by nearly 1GB. Disabling it improves performance in memory-heavy games but may cost a few frames per second, a trade-off that could matter for budget or older hardware users.

What hardware-accelerated GPU scheduling does

Hardware-accelerated GPU scheduling (HAGS) was introduced by Microsoft in a May 2020 Windows 10 update. Before HAGS, a high-priority CPU thread managed all tasks sent to the graphics card, which could cause delays and inefficiencies. With HAGS enabled, the GPU handles most scheduling tasks using its built-in hardware, aiming to reduce latency and improve performance.

Nvidia, AMD, and Intel support HAGS on select GPUs. Nvidia added support for GTX 10-series cards and newer in June 2020. AMD was the last to adopt it, enabling HAGS on the RX 7900, 7800, and 7700 in December 2023. Intel supports it only on its Arc B-series cards.

Why disabling HAGS helps budget GPUs

HAGS is required for features like DLSS Frame Generation, but it can reduce available VRAM on GPUs with 6GB or 8GB. Tests on an 8GB RTX 2070 Super showed that disabling HAGS freed nearly 950MB of VRAM, which improved texture loading in games like Cyberpunk 2077 and Stellar Blade. The trade-off was a minor drop of 3-5 frames per second.

Steam’s September 2026 hardware survey found that 8GB GPUs make up over a quarter of the market, while 6GB GPUs account for 5.12%. This means the VRAM limitations HAGS imposes affect a significant portion of users, particularly gamers using budget or older hardware.

Performance benchmarks from Tom’s Hardware and Gamers Nexus found minimal impact from HAGS. Some tests even showed slight drops in FPS, such as a 2.4% decrease in F1 2019 on a system with a four-core Intel Core i3.

When to disable HAGS

Disabling HAGS is recommended for users with 6GB or 8GB GPUs who experience VRAM-related performance issues, such as texture pop-in or stuttering in memory-intensive games. It may also help address problems in recording or streaming software like OBS, which officially recommends turning off HAGS if issues arise.

Changes to HAGS settings require a system restart to take effect. Users can toggle the feature in Windows 11’s graphics settings under "Graphics performance preference."

What this means

Lazyfounder analysis — our interpretation, not reported fact.

For founders and operators building or optimizing products that rely on Windows-based hardware—whether for gaming, streaming, or AI workloads—this insight highlights a critical but often overlooked setting. Budget GPUs are common in entry-level gaming rigs, cloud gaming setups, and even some AI inference deployments. Disabling HAGS could be a simple way to extract better performance from hardware that’s already in the market, delaying costly upgrades.

The trade-off between VRAM and FPS is particularly relevant for products targeting cost-conscious users or markets where hardware refresh cycles are slow. If your software pushes memory limits, testing with HAGS disabled might reveal opportunities to improve stability or user experience without requiring new investments in hardware.
