WoW Vanilla Use Custom Resolution

README.md

Custom WoW Vanilla Resolution

WoW Vanilla supports only as resolution up to 1920 x 1080 in the gui settings. By modifying the value directly in the Config.wtf we can circumvent that limitation.

Note: WoW Vanilla seems to struggle with multiple monitors when this method is used. It might help to disconnect all additional monitors while playing.

Because you have SET gxWindow "1", your set resolution doesn't matter. The game will use whatever native resolution there is.
