Question: Older computers

[Imp]

Got rid of an old Dell around this time last year so may have been the previous patch rather than current one.
Cant remember model but basic running XP used for email & documents while away plus of course WINSP.
Worked fine after fiddling with settings, move delay etc. AI turn took considerably longer as in do something in earshot & come back when the fan had come off overdrive but it never faltered.
