(BUG) Memory Leak in 295.51
  1 / 5    
[size="3"][b]**** The issue has been fixed with 295.73 WHQL ******[/b][/size]
Easily reproduced by playing video (non-DXVA accelerated), and watching nonpaged pool rising.
Nonpaged pool goes up rapidly (I've seen 2400 MB on my 4GB system after few hours of video playback),
can't be released, and the only way to reclaim that RAM is a system reboot.

Culprit seems to be[i] nvlddmkm.sys[/i]

[/i]
DXVA accelerated video does not seem to be affected with this.


Here is a screenie, and the [url="http://www.youtube.com/watch?v=mlvUOuo23JU&feature=youtu.be"]video[/url] demonstrating nonpaged pool rising while playing movie.

FIX: Re-installed 290.53 and no more memory leaks.
I even got my nonpaged RAM back.

Without rebooting! Gotta love hot driver installation.

75% of your RAM is nonpaged pool limit for Windows 7.

That's 3072MB for my 4GB system, but I've see "only" 2400MB stolen.

The issue here is with nonpaged memory.

Which is mostly used to hold drivers and kernel stuff that can't be paged(put on your swap file) - hence [i]nonpaged.[/i]

Under "normal" circumstantial this amounts to maybe 50-100MB, regardless of your total ram.
But if you play video with 295.51 installed it will grow and be only limited by:

available kernel-mode virtual address space, the NonPagedPoolLimit registry key value, or physical memory.

Well, as you can see it's in there a few times :)

It does seem very odd that this didn't appear during testing at all. I have to say, we've had and still have some broken video overlay using direct draw with certain renderers on dual screens. There's broken video playback in the most recent whql. Now this.

That's three clear recent problems with video playback. In each instance I'm not sure why they were even tinkering with it in the first place and surely if you are tinkering with this stuff you test these items afterwards. Well, maybe not.

This bug was already reported there. But it's good you made a topic about it. Otherwise it might go unnoticed (it might still, but at least the odds are better).

You know what, this problem is actually a lot worse. I've not tested ffdshow but what you are saying makes sense to me. I can confirm it with lav decoding as I put above.

I watched 105mins of streamed video in VLC today which uses its own internal codecs which are different to those and it's a different renderer and I found myself with nonpaged kernel memory of 1.5gigs, which was about all it could get its hands on at that time.

I quicky tested VLC and it was occuring with h264 and xvid so....I'd say if you like (or dislike and still watch I suppose) watching video it's probably best to just avoid this driver version.

EVGA 2x570 SLI
2500k OC to 4.7ghz
