That’s it. No complex installer, no registry edits. Simply launch the game. You will notice immediately that the main menu cursor glides smoothly, and in-game aiming feels tight and responsive.
It is one of the most jarring moments in PC gaming history. You install Grand Theft Auto: San Andreas , excited to revisit the streets of Los Santos. You launch the game, the iconic intro plays, and you reach the main menu. You move your mouse to click "Start Game," and nothing happens. Or worse, the cursor stutters, jumps, or moves with the speed of a sleepy snail.
Open the ZIP file you downloaded. You will typically see a few files, usually including dinput8.dll , MouseFix.asi , and potentially an .ini configuration file.
The most trusted version is hosted on GitHub or major modding sites like GTAGarage or NexusMods. You are generally looking for a file named something akin to "gta-sa-mouse-fix.zip" or part of the "Grand Theft Auto San Andreas Mouse Fix" repository by ThirteenAG.
