Graphics Card Issue?

Hey. I’m asking this here because I think this problem only manifests itself in BGE mode. Also, I don’t think it’s my graphics card, as I think it can handle more complex games with less issues.

Alright, so the problem I’m having is that sometimes, most of the game objects in Blender will disappear. It happens predictably, and happens after three or four runs of the BGE and after at least a few minutes of using Blender. It appears that shadows may also disappear / mess themselves up. I already got the latest driver for my (old) card, and tried changing the render method in Blender’s menu. Any suggestions? :frowning:

I think your graphics card heat sink is full with dust or the fan is blocked.
If this is so and you run the card over hours, the graphics card may have been irreparably damaged by the overheating.

Uhmm, for me that never happened, but blender bugs often with textures with me, the texture desapier or is changed by other somethimes, but graphic things I never saw!

I have no idea, BUT 2.49 did the dissapearing act when I didn’t have debugs on and atleast 1 debug prop showing.

@HG1 - Thanks for the suggestion. I’m currently using ATITool for underclocking my graphics card so that it won’t work so hard - I’ll see if that helps.

EDIT: Ooookay, a few minutes in, and there’s no problems so far… Instead of 500 mhz, it’s running the card’s core and memory CPUs (?) at 475, so maybe that was enough of a difference. The card is at a consistent 64 degrees Celsius, so perhaps it’s alright for now…

EDIT 2: I’m using multitexture mode in Blender 2.59, and it seems like I can run the BGE for quite awhile now without any errors. I believe the problem seemed to arise if I switch scenes a lot and test out the game… After the errors arises at first, it holds through to any other blend file I load, and makes objects with textures disappear.

EDIT 3: However, Blender seems to crash if I use the game engine several times, like over 7 or so. Maybe it’s a memory leak or something - I’m not especially worried about it, as I have Audaspace up and running, so it might be a problem with my sound factory / device creation process.

EDIT 4: @HG1 - I don’t think my graphics card has irreparable damage, but I do know that there is an issue with it overheating. If I played a graphically intense 3D game, even a graphically intense 3D BGE game, for enough time, the graphics would start to corrupt.

However, it would usually be alright for the first 30 minutes or so, so I think that underclocking my card might be a good idea, at least until I physically solve the problem. I probably wouldn’t want to run the fan harder than necessary, either, since the card might very well be clogged with dust.

EDIT 5: Ran Hegira for around 10-15 minutes in the background while I did other things, then went back and played around with it for a little bit. The problem didn’t arise again, so I hope that it’s a little better. Thanks!
