Since the 2015 Gunmetal update, Valve has used BSPzip compression for new and updated maps. Community experiments have shown that applying this compression to all maps can reduce the maps folder from 4.23 GB to 2.64 GB—a 38% reduction—without significantly impacting gameplay, though it may slightly increase initial loading times.
TF2 is heavily dependent on single-thread CPU performance. In your Task Manager, you can set the game's "affinity" to use real physical cores rather than hyperthreaded ones (e.g., selecting cores 0, 2, 4, 6) to avoid micro-stuttering.

To get "extra quality" performance—meaning high FPS without making the game look like a "Minecraft" mod—you should use optimized configuration files rather than just lowering in-game settings. Since the 2015 Gunmetal update, Valve has used
This is widely considered the gold standard for TF2 performance. It optimizes both graphics and networking. In your Task Manager, you can set the
By combining legitimate map compression techniques with a high-performance configuration like Mastercomfig, you can achieve a "highly compressed" installation that still delivers "extra quality" gameplay.
The term typically refers to a combination of two distinct goals: reducing the game's substantial disk footprint through advanced compression and optimizing the Source engine to maintain high visual fidelity (extra quality) while achieving maximum frame rates.
