The reason for wineq 2 is because of eqplaynice, which prevent eq from taking far too many resources when in use and especially when not in use. The other thing you need to check is that your paging file size is fairly large. If you are unaware how to do that you can right click on My Computer, select properties, click on advanced tab, performance click settings. then click the advanced tab and under virtual memory click change. pick custom size and type in a larger number. I use 2048 but thats because I play up to 7 on the same machine, for 4-5 1024 should be plenty. Be sure to set the initial size and maximum to the same value(ie 1024 and 1024) to prevent fragmentation and you'll be set.
for those who have been using different values and fear they may have fragmentation, set both values to zero, restart, set both values to the same number where you want the max, and restart again and you'll be fine. may want to do a full defragment too.
