But the method you choose to install it matters. The offline installer emerges as the clear winner for several compelling reasons:
You own an MSI gaming laptop or desktop. The deep hardware integration, MSI Center compatibility, and exclusive features like per-key RGB lighting effects make it the obvious choice for MSI users.
Web installers do not actually contain the software; they are simply lightweight scripts that ping remote servers to pull data down in real time. If MSI’s hosting servers are undergoing maintenance, experiencing high traffic during a major update, or suffering an outage, your web installer becomes completely useless. You will be stuck staring at a frozen progress bar.
Software has a habit of changing. The online installer always fetches the latest version at the time of installation. While this sounds good in theory, it can be problematic if a new version introduces bugs, removes features you rely on, or has compatibility issues with your specific hardware.
Once installed, open the engine settings to maximize performance: Allocate at least and 4GB of RAM to the engine.
