MyTraffic 2002 v 2004

Hello all,I had Mytraffic on FS 2002 and was able to run everything maxed out with useable frame rates (to me anyway!). However with FS 2004 I have to run traffic at below 50%. I guess the reason is slightly better graphics and far better weather. How do the traffic percentages (with MyTraffic)of FS 2004 compare to FS 2002? Will 50% FS 2004 give me the same as 50% with FS 2002?Victor
