It's worth noting that WoW uses Lua; at some point Blizzard switched from Lua 5.0 (with used a stop-the-world GC) to 5.1 (which introduced an incremental GC) specifically because of this problem. Before, UI code could generate excess tables, kick in the GC, and dramatically impact your framerate. The incremental GC significantly helped this, since it permits the GC to be run over multiple frames, reducing or even eliminating the perceptible impact on the user experience. |
