I use an AMD64 on gentoo 64 bit. What would I need to do to make wine run LotrO on just one core, or, does it do that by default anyway, in which case: How do I set it to use both to test if that helps? > > Can anyone chip in there? You need to set the affinity mask for the Wine process so that it only runs on 1 cpu, you can use a tool called schedtool, once you build or install it you run it as: cd ~/.wine/path/to/lotro ~/schedtool-1.2.10/schedtool -a 0x1 -e wine lotro.exe
