gamespeed

comment

Represents a game speed option at which the map can run. There are five predefined settings, but only SLOWEST, SLOW, NORMAL can be set and used. Setting FAST or FASTEST will automatically set it to NORMAL instead.

Warcraft 3 game speed setting:

Menu Name Game constant Speed 10 seconds is
High (default) MAP_SPEED_NORMAL 1.0x 10s
Medium MAP_SPEED_SLOW 0.8x 12.5s
Slow MAP_SPEED_SLOWEST 0.6x 16.667s
note

This setting is actually just a multiplier for a "base game speed", which is normally set to 1.0x (100%).

You can achieve a higher "base game speed" via a .wgc file only for testing. The in-game gamespeed is actually a multiplier on top of that. The results are shown in the table below:

Base game speed Game speed option Effective speed
1x 0.6x 0.60x
1x 0.8x 0.80x
1x 1.0x 1.00x
2x 0.6x 1.20x
2x 0.8x 1.60x
2x 1.0x 2.00x
3x 0.6x 1.80x
3x 0.8x 2.40x
3x 1.0x 3.00x

(v1.27, v1.32.10 tested) Restarting the map from the F10 in-game menu will reset the "base game speed" back to 1x.
