[Pocus]

Has someone tried to put his FPS to the maximum supported by his hardware -fps 999, and then disabling the background in the tac battle (key w). Perhaps the game will run at a fast enough speed. Then when you are at the situation you want to check, restore the background (w key).

Though I wonder what can be the technical issue they encounter. Ideally the data engine & renderer have only a unidirectional link data>renderer, so shutting down the rendering should pose no problem (you should be able to have a text Version of the tac replay for example, without too much hassle). Calculate the rounds as fast as possible (limited my CPU power only), then reconnecting the renderer so that the display his restored and synchronized.
