Well yeah, it's a iMac 20" 2.4GHz with 4GB RAM and the legendary (lol) Radeon 2400 XT. Just getting choppy minimising on windows etc. I'm running leopard 10.5.6 with all updates downloaded and installed. It was running fine when on 10.5.5 but as soon as I upgraded to 10.5.6 choppy graphics. I had to do a complete re-install, re-format and everything that was fine but that was my problem, nothing to do with this problem I'm discussing now boot camp ****ed that up; before the re-format 10.5.6 was running smoothly though. I'm maybe thinking it's just needing a few days to get used to it or something, build the cache up I don't know. Tell me your thoughts.
