gladiator

thanks chaps but the question still stands what causes the slow down? too many units or the resolution? poor cpu? is the combat computation against computer ai slowed up by the number of units it has to work on or by the textures on them? is a single soldier as complex for the computer to work on as say a single tank? what are sensible limitations when making a scenario via the editer when playing only against the computer ia maybe over a hundred tanks per side is to much?

I have been playing combat mission since its first emergance with beyond normandy and i have always wondered what takes my pc so long to calculate each turn? is it the video memory being used, the power of the graphics card, or processor and main memory? i have noticed that even though i have upped my cpu to amd2600xp and a gig of ram the rendering still takes as long. is it the textures on the models or is it the number of models or the size of the battlefield. i quite often have battles with just 20 or so tanks a side but as soon as infantry arrive the rendering time from one turn to the next increases. basicly i just want to cut down waiting time between turns and am willing to spend money to do it! what is the best set up to get the quickest game.
