his computer is pretty slow for any character animation, u need at least a pentium 2 or 3 , we have a dual xeon 1.7 w/ 1 gig ram and 128 nvidia quattro and even that get's slow at some tasks !
(only more than 40k poly chars.) but i suggest if u use meshsmooth check rendering and put iterations 2 4 or whaever then for view port put 0, this will speed other than that optimize ur models etc.. if u have the money search for "rational reducer" i don't have the mo ney so ... i just use a faster machine (trust me it's cheaper!)
