hi,
I Got M&M 6 working on my laptop great, but when running 7 and 8 the npc's appear normal but my character movements are slow and jerky, I have tried it in compatibility modes, applied patches, ran as admin, all things suggested to do first but nothings changing. I am running windows 7 pro 32 bit. I have updated everything and its all working correctly. Can anyone suggest anything? Thanks in advance :)

Thanks for that, downloaded the patches but still having the same problems. will keep looking for solutions though.
