I have fixed the lag in battles by lowering everything, but the lag on the campaign map is unbearable still.

I once had an ATi Radeon 9200 Atlantis with 512RAM and 2.8GHz, which ran everything except buildings and vegetation at the highest levels with AA, but was subject to memory loss and small lag on the campaign.

There was a mod here I used in those times to reduce the lag and cut the loading times or turn times - does anyone use this still - would it work in this circumstance?

Thank you for the replies, I thought I would simply be told it is all futility!

(I cannot afford to spend on anything unfortunately.. I will not be playing games for much longer!)
