catalyst 9.5 seems to be out.

I don't have windows. I am windows free since 1999

ok, this time I saw something in the first and the fourth scene (and I did not bother to watch the rest). But I am not sure that the distortion is caused by the playback and is not part of the material

Doesn't tear on a nv card so it can't be the material.

It is not part of the material. Disable Desktop Effects (compositing), use the gl2 (yuv) renderer of mplayer instead of Xv, enable VSync in Catalyst Control Center, and try again. Then, and only then, will the video play as it should.

For my eyes, Xv is almost useless in Catalyst right now.

You example video even shows extreme tearing with the oss driver in the upper area which is usually black with 16:9 movie...

[RealNC]

Yeah, it's the video I usually stick to someone's face when they say "there's no tearing" :P

Heh, good choice.

My main machine has a hd4850. Jaunty with the latest fglrx. My monitor is only 60Hz, so maybe it's because the card is too fast? As I said, happens with both fglrx and radeon. And to tell the truth, even X11 output has tearing, so I doubt it's just the drivers.

Doesn't work that way, or else videos would playback faster. I'm sure a video I watch here that is, say, 30 minutes long, is also 30 minutes long on your PC. 25 FPS here, 25 FPS there, and everywhere else. How fast the card is doesn't matter. The fact that your monitor runs at 60Hz doesn't mean anything (the video I linked to is a 60FPS video. Since your monitor runs at 60Hz, it's in perfect sync. But, it tears like crazy anyway.) Tearing is the result of the card not waiting for the monitor to get ready before sending it the next frame, resulting in the monitor displaying two frames at the same time, and a "line" is manifesting between those two frames. Some people are able to strongly perceive that line; to those people, it's very annoying. Some lucky ones don't notice it, it seems.

As I said, happens with both fglrx and radeon. And to tell the truth, even X11 output has tearing, so I doubt it's just the drivers.

X11 output is *supposed* to have tearing. There's no way to V-Sync it. Xv is not supposed to tear since the driver *should* V-Sync it. But with ATI, well guess; no V-Sync, hence: tearing.

Using Catalyst 9.5 now, stock Ubuntu 9.04 (Jaunty) AMD64, HD4770. Fixed my low res textures in Quake 4 issue, was config file options. See this thread for details.

Compiz seems smoother than with Catalyst 9.4, and of course the "Unsupported hardware" overlay is gone. Alpha blur still doesn't work (apparently it never has, according to another member here .. as if, ATI devs, come on ). Compiz's burn (fire) window close effect is really slow when in Expo mode, however is fine when viewing a normal desktop. Good way to test this is just open a terminal, run "sleep 5s ; exit", then go out into Expo and wait for the window to close itself (obviously need to set your window close effect to burn). This was never an issue with my 7900GT and nVidia drivers.

Sauerbraten (recent release in 2009) has a texture corruption issue (or something?) where enemies' fireballs look corrupted until they get close, same with health pickups and other items. Same issue occurs in the display settings menu (didn't occur with Catalyst 9.4)

Nexuiz 2.5.1 appears to work fine.

Scorched3D 42.1 appears to work fine (windowed, under Metacity).

Playing a video (the one RealNC uses to test for tearing) under VLC with GLX output is perfectly smooth (with Metacity as WM, no compositing), until I drag another window over the top of the GLX output.. stutter deluxe. I don't recall this being an issue on my 7900GT either.

Hmm, yep, nVidia's binary drivers seem to be A++. Definitely, "The way it's meant to be played"
