M17x DPC Latency

[.breath]

After one hour of testing with the new driver i got these results.

Absolute maximum dpc spike 1405. I didn't hear any audio stutter, stop, noise etc.

I played 2 youtube videos 1080p side by side on chrome, 1 internet streaming radio, 1 mp3 with windows media player, scrolled a bit some .pdf, repeatdly opened and close browser windows, moved mouse around fast and randomly (setted on 500hz ill test if the 1000hz setting will give problems).

I'll play some games later, but i never had any fps problem, so i dont think ill get now.

About dpc lat, i never got any red spike (normal usage, i dont even read ppl talking about red spike when the notebook is going out of sleep or ejecting the dvd, i have seen so many laptops acting strange in these situations, i know too well that these are critical stuff and dont matter in testing (or real usage)), so, no red spikes, some yellow, rare, about 1 bigger green every 15 seconds. Also would like to add that the using the System Temp monitoring software (HWmonitor), results in some more bigger green spikes, never red.

I'd say atm its everything all right, just the only thing is that when i installed the beta driver it seemed to mess up with the nvidia ethernet driver (yellow ! on the device manager), just had to reinstall that driver.

Ill probably do a format and clean install of everything in these days.

ok its a usb mouse? its microsoft?

thus can you scroll the pdf file inside stamatisx test? in fullscreen please.

I used his test playing 2 1080p youtube videos, mp3 with visualizer, scrolled with pdf fullscreen for 30 secs constantly. Not one red spike. Here's a screenshot after the test.

I've done pretty much the same tests as in the posts above - No red spikes. Just from the eject button now which isn't even worth my time to think about.
Seems they did a good job with the driver - Not having much knowledge in the driver department i'm just hoping they haven't done anything to decrease performance.

Performance wise, running 3dmark vantage I scored 500 more points then with 186.82 drivers. One big downside atm is that I need to press the F8 everyboot

Finally..
A03 and the 196.86 beta drivers resolved all latency/stutter issues of my M17x.

Thanks NBR!

Me Dos!!!! Wooo

Dell-Bill, can you pass that information along to the engineers please? Thanks!

I'm pretty sure they saw it. A few of them are watching the Nvidia thread and this one. I know they're keen to pick up on anything that shows how AW engineers were instrumental in getting some movement on this, such as a Clevo owner modding our inf and posting results.

Here is a screen of me just surfing on tumblr, site where people post pics. All I am doing is scrolling through firefox and clicking on the next page link. Nothing else going on at all...

Have you got a copy of Win7, or interested in seeing what happens in Win7 instead of Vista?

Long lunch. Back in a couple of hrs.

guys can someone please try to reproduce my tests...

switch off SLI, monitor your GPU clock, let your GPU clock down to the minimum state, and suddenly stress it with a movie or 3d application. I'm getting single 18k spikes when the GPU goes up from level 1 to level 4 clock, but all other transitions are clean.

seems like there is still a DPC problem when the GPU jumps up clock rate too fast. you wont be able to reproduce this if you run a thousand different applications at once, you need to let your GPU downclock to the minimum

hehehe thanks Bill, my pleasure

Yes there are still DPC spikes with the new drivers. But it is MUCH MUCH better than before. I dont notice any audio stuttering anymore unless i stress out the laptop.

Nicely done.
