Posted this aswell on Dual-boxing, but I think here it would be better in place.
Short info:It worked before I stopped playing in June, no big changes on my side, only monitors swapped on the desk... no new hardware/software. Just Wow5.x
Updated wow to new version, and started. playing.
HW: gtx560ti and gtx275 for the 2nd+3rd screen.
SW is unplayable now, fps on the main screen is bad...<24fps, stuck at 13 most of the time.
Did a fresh install of windows+wow (so no addons and whatever)+isboxer.
Removed maxfps in wow and isboxer.
Starting wow.exe gives 85+ fps. (double click on wow.exe), screen setting is 1680x1050 windowed.
Starting wow from my new freshly wizarded ISboxer.... 25fps with luck. Staying at the same spot.
Loginscreen started from isboxer does 400+ fps, hard to read.
Here is my isboxer setup.
I am completely clueless what might be causing this problem, reinstalling everything did not solve it.
My girlfriend also plays wow, multiboxes it too, and has no problems, with the same setup. (GTX560=GTX460)
Keep in mind it did work before.
My old xml is still available, but suffers the same problems like my new one.
Looking forward to some tips...
