Does Disabling Sysmain Improve Performance For Gaming & FPS in 2024?

I turned off Superfetch on Windows and it solved 90% of my performance issues.

In the world of gaming and FPS enthusiasts, the debate over whether to disable Sysmain, also known as SuperFetch, is a topic that frequently surfaces.

Gamers often seek ways to enhance their gaming experience, and some believe that disabling Sysmain can lead to improved performance and FPS (frames per second).

The discussion revolves around questions like, “Should I turn Sysmain off for gaming?” and “Does disabling Sysmain really boost performance?

In this article, we’ll delve into these questions, explore the impact of Sysmain on gaming, and provide insights into whether toggling this setting can be a game-changer for your gaming sessions.

What is SuperFetch/Sysmain & Purpose?

Sysmain, also known as SuperFetch, is a Windows service designed to enhance system performance by predicting and preloading frequently used applications into the system memory (RAM).

The primary goal is to reduce the load times of applications, making them launch faster and improving overall system responsiveness. SuperFetch analyzes the user’s usage patterns and learns which applications are frequently accessed, preloading relevant data into RAM to make them readily available when needed.

In essence, Sysmain is a feature aimed at optimizing system performance by proactively loading frequently used data into memory, but its impact on gaming performance remains a subject of discussion among users.

Does Disabling Sysmain (SuperFetch) Improve Performance?

The opinion varies on whether disabling Sysmain (SuperFetch) improves performance. Some users on Reddit suggest that turning off Sysmain can lead to better gaming experiences, especially if they encounter stutters or high CPU usage during gaming sessions. Disabling Sysmain is seen by some as a potential solution to address these performance issues.

However, it’s essential to note that there are differing perspectives, with some users pointing out potential drawbacks. Disabling Sysmain may result in increased RAM usage since it also handles memory compression. Memory compression is a feature that reduces RAM usage by compressing data but may use additional CPU resources in the process.

In conclusion, while some users believe that disabling Sysmain can enhance gaming performance, it’s crucial to consider the trade-offs and potential consequences, such as increased RAM usage and the impact on other system processes. Users are encouraged to test and assess the impact on their specific system configurations before deciding to disable Sysmain.

Sysmain On or Off for Gaming (Pros/Cons)

This could lead to higher RAM usage as it preloads data into memory.May use some system resources to pre-load frequently used data.Reduces memory and CPU usage, potentially improving responsiveness.
Game Loading TimesMay contribute to faster game loading times by pre-loading data.Loading times might be slightly longer as data isn’t pre-loaded.
RAM UsageCould lead to higher RAM usage as it preloads data into memory.May reduce RAM usage as preloading is disabled.
CPU UsageUtilizes some CPU power for data pre-loading.Low CPU usage as pre-loading is turned off.
Stuttering & PerformanceMay cause occasional stutters during background data pre-loading.This may lead to a more responsive system during gaming.
Overall Impact on GamingThis may result in smoother performance without background pre-loading.May lead to a more responsive system during gaming.
