Hi

i'm a interactive visual designer for theatre/installation and i run some very complex realtime system using touch designer
www.touch077.com

it is not a well threaded application so it is common practice to have multiple instances running and shunting data around to achieve output

i have run into a throttle even when i'm not at 100% across all 4 cores, in fact i'm at 63% according to task manager and at 72% GPU load
4 intances running

its a longer throttle cycle than on the synthetic benchmarks posted, but the drop in performance is certainly noticeable and imho, unacceptable for performance. i'm getting rough 88msec rendering time per frame at 550mhz, dropping to 224 at 383
a 2/3 drop in performance

(sorry i was working on some other phtos and accidently layered the waterfall. but the details were as above)

also while a synthetic measure, of note i'm running into the throttling problem with intelBurn running with only 2 threads and furmark

it also throttles in assassins creed

(please note that it was run in full screen, not windowed, i just did that to get a piccy of both assasins creed and GPU-Z)

i think that it is reasonable to expect that a notebook of this calibre could handle this without throttling
if the laptop can't even run at stock settings then i guess anyhopes that hte extreme edition chip and its unlocked overclockability is gone?

i'm running an m15x with the i920xm chip and 8gb of RAM
latest nvidia drivers with 'prefer performance' selected
195.62 and the A02 drivers, windows 7 64bit, 256gb SSD

-John, can we expect a fix for this or is it a design feature as seems to be the official line?
i do love my machine, and it is very fast for a laptop. BUUUT, for the $7400AUD i paid for it, and the fact that i rely on it for realtime performance and work, i'm very disappointed to find that it falters when pushed even moderately hard...
and i for one certinaly do not accept that computers aren't designed to run at 100%
they damn well are - thats what they're good for: render farms, number crunching, servers i dont accept that anyone would design a cpu that is only design for occasional bursts of speed.
