--- Comment #6 from winebugzilla.kyoo@xoxy.net 2009-11-07 02:40:11 --- The two options that I see labeled "Sync to VBlank" are now checked. I see none with "vsync" in the name. Ragnarok Online still takes 90-100% of the CPU. Less, by necessity when more than one copy is running. With two copies running, the game is slightly jerky on both copies.
