It seems very unlikely that there is a solution to this considering that you're talking about old hardware not working as well as new hardware, which is to be expected.
sorry for triple post, i cant seem to get the edit button to work,
here ya go :D, if theres anything i should omit for security purposes, (i glanced over it, looks fine) because im not sure really, i assume its all just system specs, but tell me if i should censor any information.
everything in DxDiag cannot be used against you, all it contains is the system specifications, your connected things (Like speakers etc) and general info about your computer (Model, Name, Computer Name) etc etc. I don't see anything wrong with it, but i'm not that good with looking over things, what are your settings on both computers.
