Hi,
Once loaded i also tried to /console maxfps 45 and /console maxfpsbk 45 but it didnt change anything.
maxfpsbk should be MUCH lower if you are having performance problems, perhaps around 5. This limits the FPS on background WoW windows to the indicated number.

As keyclone has noted, this expansion is significantly more resource intensive than BC. IMO, a quad-core CPU is probably needed for satisfactory performance if you're trying to 5 box on one machine. In addition to dropping your display detail, make sure you are not running any WoW addons. You can add these in later one at a time frugally after your system reaches an acceptable performance level, assuming it can.

If the differences are truly seen only when running keyclone, that's pretty weird. When you say "If i run wow without using a keyclone everything runs good.", are you running multiple copies of WoW just as you do when you run keyclone? If so, you can run keyclone _after_ all your WoWs startup and I suspect you will find it has little to no impact. If that's the case, tweaking with your CPU affinity and maxfpsbx settings in keyclone may be helpful.
