Hello again, once more posting another problem I've had and hoping that you guys can help out.

Our game, Kino One, has some random video pause issues. What I mean by that is the video just kind of pauses while the game keeps going. It's not the engine being paused that's a definite, I've tested to make sure that's not it.

The odd thing is that when I change resolutions or go into window mode and come back to full screen while the video is stuck, it fixes itself, but the problem will occur again.



According to the manual certain shaders can cause video freezes, which is what my problem is. And here's the curious thing....the problem only occurs on Nvidia Chipsets from the tests that we've done. I'm not sure if Ati has some kind of error correction for shaders or something, but there's no problems on them so far.

Also, I tested each shader to make sure if they could be the problem, but I don't think so. I've removed all but FFP shaders and still got the lock. If need be I can give you all the shaders so that you can see if there is something wrong. Just ask for more info and I'll give as much info as I can, and will provide tests and results.

My question is has this been reported before? Has anyone here had the problem? If so were you able to fix it and how.

No, this has not been reported before. I don't think shaders can affect video streaming. It could be a problem of the CODEC of the video format that you're using.

There are no videos playing, I mean to say that the video just freezes, I think it's a video driver failure, but it doesn't record anything in the acklog. Audio is still going and if I change resolution or go to window mode, it'll fix it.

That means it can be a. a driver issue (most likely!!) or b. something with your graphics card(s) (unlikely, but plausible) or c. your motherboard might be dying on you (possible) or d. bad RAM (don't know how likely or possible that would be).

I'd reinstall the drivers and make sure to clean them properly first. Other than that, I can only say that I am using A6.60 all the time and never ran into rendering issues like that. On both ATI and Nvidia hardware and with or without shaders.

There are of course certain shader related commands that make a code act differently on Nvidia graphics cards, but in most cases this shouldn't cause a freeze of rendering.

Cheers

It could also be a hardware defect of the PC, or the video hardware. How much power does it consume? Is the power supply sufficient? Are you using overclocking?

can't be any of those, nope not using overclocking, and on A6, only this game messes up. And the problem occurs on multiple systems, any systems that have a GeForce. And the problem is so random that sometimes you can play and it won't happen, sometimes it will. It's can't be any computer based problems because of the fact that happens with : A. Nvidia chipsets 2. It happens on multiple systems, and no they aren't having other problems no other games (even A6 ones) mess up.

We also think that the problem may come from the fact that it may be a shader issue and it may be because it's not compiled.

You could temporarily disable all material effects and check if this fixes the freezing.

When the program freezes, does it still react on keys? Or is it completely frozen?

It still reacts to key presses and everything, all the sound plays. Everything keeps going except for the video being frozen. It may be a refresh issue and a shader caused it.

There's just one problem, we use .fx files on the models directly, so to remove all the materials, we have to remove them from the models.

We also think that compiling may fix the problem, which we'll test soon. Have you ever heard of this happening?

Set the NOSHADER flag for the camera view. This disables shaders and then you can see if they were the reason.

hadn't thought of that, I'll probably try it this week at work. Anyway we think we'll test building it and seeing if the problem occurs then, if not it may just be a fluke. :P
