DAZ Studio 4.7 keeps causing access violations against my video driver

ken-2263604

I upgraded to Daz Studio 4.7 last night (now wish I hadn't) and ever since the upgrade, Daz Studio has been causing access violations against my video driver and then crashes. Specifically, I get the following error:

DAZStudio.exe caused ACCESS_VIOLATION in module "C:\Windows\system32\nvoglv64.DLL" at 0033:0000000069188BD6, DrvPresentBuffers()+2400806 byte(s)

This was not happening with the same scene under Daz Studio 4.6.

The scene is quite large and Daz Studio is using over 8GB of RAM when it is open, but Daz Studio 4.6 was able to handle it. Even though the scene is large, because these are access violations and they weren't happening under 4.6 I tend to think it is a new bug in 4.7.

One workaround would be to reduce the size of the file, but I haven't been able to keep the scene open long enough under 4.7 so that I could eliminate/simplify some elements. I'd probably go back to Daz Studio 4.6 if I could since it wasn't having problems, but I don't know if that is possible. I'd love to know some settings I could do that might make it possible for DAZ Studio to handle larger project sizes like mine. I could live with less rendering detail through the design phase as long as I could get full rendering quality when it came time to render final images.

For troubleshooting purposes:

I'm using a Lenovo Thinkpad w520 (4270CTO) with 32GB of RAM and a NIVDIA Qaudro 1000M graphics chipset. It runs 64bit Win7 Pro. All drivers and software are updated to their latest versions.

go to preferences and turn down all your preview settings and turn off unneeded ones, the ones that are using opengl and your card, it will only affect viewport not render

Thanks!

That seems to have done the trick. On the interface tab all I did was disable animations and set the texture resources to the next to highest quality setting (it was at the highest quality). The crashes seem to have stopped. RAM usage is still up around 9GB, but no crashes so I'm happy.

I do like the look of the 4.7 interface. It is way more compact than 4.6, which means more space for the viewport.
