: StarCraft II allows you to start playing at an "Optimal" point (roughly 6GB), while the remaining ~24GB—containing high-resolution textures, cinematics, and high-quality audio—continues to download in the background.

While V-Sync is often shunned for introducing input lag, it is required for one of the most powerful performance tweaks. Set "Vertical Sync" to in the game's options. Then, force it on in your GPU's control panel (NVIDIA or AMD), and set "Triple Buffering" to Force On . This combination has been reported to provide performance boosts of 10 FPS or more, especially during large battles, by smoothing out framerate delivery. starcraft 2 preparing game data extra quality

It turns out, the seemingly simple act of loading a map is a complex intersection of Blizzard’s server architecture, high-fidelity texture streaming, and a strange player obsession with minimizing the wait.

This is one of the best "free performance" tweaks available. In your Variables.txt file, find or add the line transparentshadows=1 and change it to transparentshadows=0 (zero). Disabling this feature often yields an additional 5-10 FPS gain with an almost imperceptible visual difference in most gameplay scenarios.
