Weird Artifacts in Videos

Recommended Posts

Hello,

So I have an Alienware Aurora mALX, with the works. Basically, everything but the Blu-Ray drive. Dual 7950 GTXs in SLI mode, currently using 177.66 for Forceware, courtesy of this site. It seems that no matter what Forceware version I use, I always get weird artifacts while playing videos, even off of the SATA drive. For example, in the just-released 720p trailer for Midnight Club, I grabbed this screenshot of what can typically be seen when it messes up. The screenshot is following, and then my system info from the NV Control Panel afterwards. Thanks!

Oh, I have the KLite Codec Pack installed, a mega/full version.

A few questions if u don't mind. Are u using any filters or image enhancements in ffdshow video decoder? Does this artifacting occur in all videos like

avi, mpeg2, mkv, mpeg4, h.264, Etc. And are u using any nvidia based enhancements such as inverse telecine?

And last one, have you tried disabling sli then playing a video?

No problem, whatever can get me closer to a solution. The installation of ffdshow has been untouched, so whatever are the default settings are what it has turned on. I'd say this happens for videos of all types, except web videos like YouTube... Oh and I haven't a clue what inverse telecine is, so chances are that is not enabled.

I will try playing the video with SLI disabled (Moving a ton of files in preparation of a different secondary hard drive so I'll try it right after), but I'd much rather have it on so I don't have to remember to turn it on while gaming and of course run that risk that I'm required to reboot to re-enable it, such an annoyance...

What are your gaming/idle temps? Are you having problems with other games. This problem could be driver related.

I cannot check temps for whatever reason, perhaps because of it being a mobile system? The only temp I get is that of the CPU, which will stay around 75-80 deg. C. when running games like Mass Effect, but cooler otherwise when playing video... Oh I just remembered this issue also doesn't exist for Joost.

Well, I just tried 177.79, and now the video simply stops for a second or so every couple of seconds while the audio kind of stutters, so yeah this is most likely driver related. Should I just forgo extra performance and go back to what Alienware has, 86.14???

Edit: I just found 175.28 on their drivers page, going to try those and see what I get...
