Hi all, I wonder if somebody can help me with what is becoming a very annoying problem.

Basically I am getting crashes with layout v8.5 on PC - it is something to do with the OpenGL I believe.

Basically in layout the OpenGl is jerky in that it moves OK for a few seconds then freezes and then redisplays the layout. You can use layout like this (annoying as it is) but within 2 or 3 minutes layout crashes completely - please see the image attached that shows the error message.

My machine is:
AMD Dual Core 4800+ on a Asus SLI Premium mobo (A8N-SLI)
GeForce 7800GTX (just the one!) running Forceware 84.21
2Gb RAM
Win XP Pro 32-bit (fully patched etc)

If I go back to 78.01 Forceware drivers then things seem OK - but I really would rather not now as the later drivers are obviously designed for performance and comaptibility with the latest applications.

If anybody has any suggestions how I might overcome this I would be very grateful - and don't say by an ATI card!! :)

Otherwise I will need to head back to the old drivers :(

Many thanks.
Steve

Sorry all, I guess I should I have posted this in the PC Support forum rather than here.

It's not uncommon for a particular video card driver release to break something in OpenGL, although nVidia is usually pretty good about not doing that. However, if installing a newer driver slows the system down that considerably, the older driver may be a better choice until nVidia hands out a new one.

I'm using 8.1.9.8 and that seems fairly stable. If you manage to get hold of that one and you're still having problems, it could be memory...

Quoted for truth.

You just answered your own question. I would contact NewTek support and see if they can confirm the issue. If they can verify, they can open a case with nVidia.

Thanks for everyones replies.

I have already filled in the support request on the Newtek website (about 5 days ago) and so I am waiting for them at present.

There is abother thread in the PC Support Forum with posts about this issue also, for clarity and to reduce confusion and duplication I will follow up on there rather than here.

Thanks again.
