For gamers seeking to maximize the performance of their multi-GPU systems, the EVGA SLI Enhancement Patch 26 offered a solution for enabling Scalable Link Interface (SLI) support in newly released games. This article provides a comprehensive overview of the patch, its functionality, considerations for its use, and alternative driver resources.
Understanding SLI and the Need for Enhancements
SLI, developed by NVIDIA, allows compatible graphics cards to work in parallel, theoretically increasing rendering power and improving frame rates in games and other graphically intensive applications. However, for SLI to function optimally, specific profiles need to be created and implemented within the graphics driver. These profiles contain instructions on how the workload should be distributed between the GPUs for a particular game.
New game releases frequently lack these pre-built SLI profiles. Without a proper profile, the potential performance benefits of SLI are unrealized, and users may experience issues such as:
- Lower than expected frame rates
- Graphical glitches or artifacts
- Poor GPU utilization
The EVGA SLI Enhancement Patch 26 was designed to address this issue by providing an immediate solution for enabling SLI support in the latest games, bridging the gap until official driver updates incorporating the necessary profiles were released by NVIDIA.
How the EVGA SLI Enhancement Patch Works
The EVGA SLI Enhancement Patch 26 operates by adding or modifying existing SLI profiles within the NVIDIA driver. This effectively tells the driver how to properly utilize the multiple GPUs in an SLI configuration for the specific game targeted by the patch.
The primary objective of the patch was to offer a rapid turnaround time, ideally within one day of a new game or demo release, to ensure that SLI users could immediately benefit from the increased performance. This proactive approach allowed gamers to enjoy a smoother and more visually appealing experience from day one.
Key Considerations Before Applying the Patch
While the EVGA SLI Enhancement Patch 26 provided a valuable service, users needed to consider several factors before installing it:
- Relevance: The patch was only necessary for users running SLI configurations who were playing games lacking official SLI profiles. If you didn’t use SLI, or the game you were playing already had a working SLI profile in your existing driver, the patch offered no benefit.
- Dual-GPU Cards: The patch was also beneficial for users with single dual-GPU cards, such as the 7950GX2, 9800GX2, or GTX 295, as it could improve performance by properly utilizing both GPUs on the card.
- Custom Profiles: Installing the patch reset all existing SLI profiles, including any custom profiles created by the user. Therefore, it was essential to either avoid using the patch or recreate any custom profiles after installation.
- Driver Updates: The patch was intended as a temporary solution. Once a new NVIDIA driver was released containing official SLI profiles for the games addressed by the patch, it was generally recommended to update to the official driver and remove the enhancement.
- Driver Compatibility: While the patch might have worked with older drivers, EVGA only recommended using it with the driver version specified in the patch’s documentation. Using it with untested drivers could lead to instability or unexpected behavior.
- WHQL Certification: Applying the EVGA SLI Enhancement Patch 26 voided the WHQL (Windows Hardware Quality Labs) certification of the NVIDIA driver. WHQL certification signifies that the driver has been tested and approved by Microsoft for compatibility and stability. Using a non-WHQL certified driver could potentially lead to system instability, although this was generally considered a low risk for a patch from a reputable source like EVGA.
Removing the Enhancement
If necessary, the EVGA SLI Enhancement Patch 26 could be removed by uninstalling the NVIDIA display drivers through the "Add/Remove Programs" (or "Programs and Features") control panel in Windows, and then reinstalling the drivers. This process effectively reverted the driver to its original state, removing the modifications made by the patch.
What’s New in Version 26
EVGA SLI Enhancement Patch 26 specifically enabled SLI support for the Supreme Commander 2 Demo.
Downloading NVIDIA Drivers (Including Alternatives)
While the EVGA SLI Enhancement Patch 26 is no longer actively supported, ensuring you have the latest official NVIDIA drivers is crucial for optimal performance. Below are several reliable sources for downloading NVIDIA drivers:

Note: Always verify the driver version and compatibility with your graphics card and operating system before installing.
Conclusion
The EVGA SLI Enhancement Patch 26 was a valuable tool for SLI enthusiasts, providing a timely solution for enabling SLI support in new games. While the patch itself is outdated, the principles behind it remain relevant. Understanding how SLI profiles work and the importance of keeping your graphics drivers up-to-date are crucial for maximizing the performance of multi-GPU systems. Always prioritize official drivers from NVIDIA whenever possible, and be mindful of the considerations outlined above before applying any unofficial enhancements.
