I have 2 computers that run the same macros,
on windows xp (non-SLI) this example loop will execute pretty fast

<begloop>(99)
<getpixel>(10,10,color)
<if>("color == somenumber")
some command
<endif>
press a key
<wx>(35,0)
<endloop>

but on windows 7 with SLI 2 Geforce 8800 gtx it runs
like the wait interval is 700ms instead of 35ms.

The only reason why I concluded this might be a problem with SLI
was one time on windows 7 the graphics driver crashed (with the windows titlebar
semi-transparency isnt working) and i noticed that the slowness isnt there anymore!

i didnt check the nvidia settings if SLI was turned off when the crash happened,
i just assumed that might be the problem. or maybe its something with windows 7?

k i have confirmed that it isnt the SLI thing. because I turned SLI off and it's still slow.

for now I can live with it

i finally figured it out. on windows 7 i disabled "enable desktop composition" and it worked fast

system properties > advanced > performance options > visual effects

for future reference
