This error is the canary in the coal mine for unstable GPU clocks. If you have an overclocked GPU (RTX 3060 Ti, RX 6800 XT, etc.), the error will happen frequently during the loading screen because the shader compiler is the most sensitive workload.

The PREGFXMPFF error often occurs because the GPU driver takes longer than 500ms to fetch a texture. By limiting VRAM usage to 65%, you leave a massive safety buffer. The game no longer has to "hunt" for memory.

In plain English: The game tried to load a texture, shader, or 3D model for a multiplayer match, but the data it read from your system was corrupted, missing, or timed out. The game panicked and crashed to prevent a hard system freeze.

Most instances of this error are resolved by clearing the game's temporary cache or updating system software.
