I receive Aero Lag when opening and closing windows in Windows 7

EPIC FAIL!!!

Oh this was way too funny to pass up talking about. I was on Hulu about to watch a Family Guy episode. Of course after the intro there was a commercial, in this case a Win7 commercial. And 3/4 in to the commercial, BAM! LAG! It was an epic fail.

I do have a spare PS2 mouse, I think. I will look in the morning. In the meantime, I've posted a link here to my Conflicts/Sharing.

I also join the club. At the end of the opening animation and at the beginning of the closing animation there is a stutter. My computer:

1. Nvidia GeForce 7300
2. I tried everything: driver from Windows Update, latest final driver from nvidia.com and beta driver 195.39 from nvidia.com
3. Clean Install, no upgrade
4. Motherboard: Asus M2N-SLI

On a blank clean installation, withouth crapware or anything else, with all driver up to date, without any overclocking, I have this problem.

Yes, my graphic card is not fast, but every Aero animation is running as smooth as I can imagine besides exactly two things: opening windows and closing windows. This point and the fact, that people with high end graphic cards also have the stutter problem, let me think, that my slow graphic card is not the problem.

My laptop with integrated graphic unit and running Vista is not as fast as my desktop pc. But it can close and open windows without stuttering. I also tried the "Aero animation slow motion registry hack" on the notebook (Vista) and on my desktop pc (Seven). The result: Seven Aero is stuttering in real time and in slow motion. Vista Aero is not stuttering in real time and is not stuttering in slow motion.

The problem is opening and closing windows. Everything else is smooth.

Is there anybody without this problem? If yes, could this person please make a slow motion video of opening and closing windows? That would be nice. Thank you.

I use an M2N-SLI Deluxe myself, but with an 8800GS TOP from ASUS as well. I don't, however, use the onboard sound (switched off in bios settings, no driver or anything) as I use my Audigy 2 instead.

I think the onboard was the Realtek High Definition Audio Controller, though I might be remembering wrongly. Can you check your drivers? Are you using the latest Nvidia chipset drivers (without the network management software if it offers to install it, just the drivers) and graphic drivers from Nvidia web site (not ASUS)? The latest Win7 drivers reported for my vid card from Nvidia web site are 191.07, are your's WHQL? They seem to be newer (beta?). Are you using the latest Realtek audio drivers?

If you can post your essential IRQ numbers it may provide further insight. It may not, of course...

And quite where do I go to find audio chipset and driver info on that?

Here is a link to see my IRQ's I'm no expert in these kind of things.

Now pardon me while I reboot, again.

Hmm. The vid card and audio is not sharing, but the audio is sharing with the standard USB controllers (though not the enhanced ones, which do share with the vid card). My vital IRQs (the usuals stripped out are the same as yours) are laid out as follows:

(PCI) 040000010  (16) JMicron JM836X Controller

(PCI) Ox00000010 (16) NVIDIA GeForce 8800 GS

(PCI) 040000012  (18) Creative SS Audigy 2 (WDM)

(PCI) Ox00000013 (19) 1394 OHCI Compliant Host Controller

(PCI) Ox00000013 (19) Texas Instruments 1394 OHCI Compliant Host Controller

(PCI) Ox00000014 (20) NVIDIA nForce 10/100/1000 Mbps Ethernet #2

(PCI) Ox00000014 (20) NVIDIA nForce Serial ATA Controller

(PCI) Ox00000014 (20) Standard OpenHCD USE Host Controller

(PCI) 040000015  (21) NVIDIA nForce 10/100/1000 Mbps Ethernet

(PCI) Ox00000015 (21) NVIDIA nForce Serial ATA Controller

(PCI) Ox00000015 (21) Standard Enhanced PCI to USE Host Controller

(PCI) Ox00000016 (22) NVIDIA nForce Serial ATA Controller

(PCI) OxFFFFFFFD (-3) PCI standard PCI-to-PCI bridge

(PCI) OxFFFFFFFE (-2) PCI standard PCI-to-PCI bridge

Not quite sure what the last two are up to, but if it works...

Note that my vid card only shares with my external SATA port (unused so no issue there) and my audio card is on its own. Your resource setup shouldn't be a problem, but could be an indicator as to where a problem will show up if there is one.

I believe Realtek are providing your audio, so there should be a Realtek driver in the sound section of the Device Manager. There may be newer Win7 drivers for this around.

Of course, IRQs shouldn't be a problem but sound cards are notorious for causing stuttering as the first sign of resource issues. Thing is, this can be caused by so many things (memory, PSU, latency in drivers, mobo, IRQ issues from OS, IRQ issues from mobo, badly written audio drivers etc.). When the sound does go screwy, it can cause other things to stutter as well.

Such issues are much less common now with modern motherboards and OSs, but if Windows 7 or the drivers are not working correctly anything is possible.

I am considering the theory that either Windows 7 is handling the resources poorly for some reason, or the mobo or device drivers are, and your mouse (USB I can see, as there is no PS2 resources allocated to it) is fighting with your audio. They should play well, but if they don't then this might influence things.

I wonder, what happens if you use a PS2 mouse? Or even a PS2 keyboard (a USB one could possibly cause the same effect of course)? Do you have one about, or did the mouse come with an adapter?

It's worth checking for new Win7 motherboard chipset drivers (motherboard manufacturer's web site) and new Win7 audio drivers (Realtek web site, if I guessed the model right).
