Heya! I have an issue with LightWave 9.6 on Win7. It does occasionally crash my display driver (only when i drag my cursor holding LMB). Disabling Aero did not help(but fixed same issue with Adobe Photoshop). I can't register on nVidia forum(tried 2 times, but not receiving confirmation mail). So i have no idea, how to fix it. Any suggestions?

P.S. Config:
Win 7 x32;
Core i7 920;
3GB RAM working(4GB real);
GeForce GTX 295(Drivers = 197.45);

I'm currently using Win7 64 and have been using mostly LW 9.6 32-bit (for plug-ins) and some 64 bit for Layout and I'm using the 197.45 drivers with no issues (9800GX2). I am also using 196.21 with Win7 32-bit + GTX285 without any problems.

If you can't find the 196.21 driver and haven't tried it, let me know and I will post it or send it to you.

EDIT: With your system, I highly recommend going to 64bit Win7 if possible. The differences with Vista were nominal, but I have found that the 64bit version of Win7 is quite 'zippier' than the 32 bit version.

Try this.

1. Delete the Nvidia folder on your C: drive.

2. Uninstall your current driver.

3. Boot into safe mode.

4. Install drivers.

This may also help.

Good procedure and usually works when you have strange nVidia issues. Also, Guru3D does exactly what it says it does and is a fine tool to have.

And it's free.

According to google search, this crash is more GTX2xx-specific.

P.S. about x64 i'm not going to use my W7 x64 installation before i get additional 4GB of ram to compensate memory usage of x86 applications on x64 platform. But i can't see a reason to do that while any application can't to use more, than 2GB.

P.S. Sorry for bad english, i hope you understand everything.

Nop, still crashes. And yep, i've tried 196.21 driver before, but it didn't help.

That's the spirit.

When running a x64 OS, LW x64 will access all available memory.

So i don't have idea now, what to do(except of learning that suckin' 3ds and spending tons of money on license D:). I'm sure, that's nvidia fail, because i had crashes with photoshop too. So it looks like major OpenGL bug.

Hmm...Probably fixed by disabling SLI for LightWave Modeler/Layout. My bad, forgot about 2 GPU's often causing compatibility problems. I'm not sure, but worked for ~1 hour without crashes.

Sir, your command of the English language is quite commendable and better than most native speakers.

I have definitely noticed that having an application set to the default "Mutli-GPU Mode" in the nVidia control panel can cause serious issues even though the application is obviously not full screen SLI capable. When set to this mode, the firmware of the card is attempting to use both GPU's for frame buffering, which can wreak havoc on OpenGL applications like LightWave.

Disabling SLI just reduced crash rate. But it still happens. So i totally need nvidia.com forum account.

Im wondering if this is a case of bad driver support, just thinking of
the term certified drivers when using quadro fx cards as opposed to gtx cards.
just wondering.:stumped:

since Im about to choose between gtx 280 and quadro fx 3800 cards.

I've updated to nVidia Beta drivers(257.15). I'll post in case i'll experience crashes again.

You could try different shading methods in LW in the opengl tab and see if it makes a difference.
