Hi, I have just purchased a new computer with a GEForce RTX 2070 graphics card. When I set the advanced option in the Render Settings to use only the GPU all I get as the result of rendering is a black image. iRay worked just fine under the same settings with a GeForce 1050 as well as a GeForce 1080, but with this new card it isn't.

I know the iRay plugin has been loaded correctly by looking at the information about the plugins. NVidia iRay has a green icon. I also know that Daz Studio recognizes the card correctly because it shows all the things the card supports under Help -> Troubleshooting -> About your video card. Yet when I start a render the dialog that shows the progress of the render never even mentions iRay and it closes in less than a second giving me a completely black render.

I have updated the card's driver to the latest one and nothing has improved.

I have tried this with Daz Studio 4.11, 4.10, and even 4.9 and the result is the same.

I can render images using the CPU but it takes way too long and at that rate why have such a fancy graphics card if it doesn't do the render?

Any help on this subject will be greatly appreciated.

The driver was updated from nVidia, not from Windows Update? You can check the current version number from the nVidia Control panel. launched from the Windows desktop right-click menu.

Only 4.11 will support the 20x0 cards, so not working with 4.9 or 4.10 is expected.

You are a rapid responder, RHaseltine :)

Thank you very much for the response. After installing the latest driver (from NVidia) and re-installing Daz Studio 4.11 the problem has been solved. You have no idea how happy I am after sinking a lot of money in the new computer with the fancy graphics card. Thank you.

One item of note - Windows Update (Windows 10) likes to update itself without your permission (or even notification.) Might want to go look up how to keep that crap at bay (I set my connection to "metered", which keeps it stopped unless I feel like updating.)

The back-story is that Microsoft and nVidia are still arguing over WHQL certification - the decent nVidia drivers don't have it, the craptastic Microsoft-written one does, so guess what replaces your decent, working GPU driver every time Windows updates?

I seem to have turned this off somehow - I believe it is an option, though I can't recall where.

If you leave your updater turned off for too long, MS will tell you that you can;t update without executing a full re-install of current version. This means re-installing all software on your system. I miss service packs!

Agreed, on both counts (SPs made things much easier.) I usually get around the update bung-up by updating when I have the time to do it (roughly once a month, sometimes once every two months), so I know to go back in and re-replace the crappy MSFT driver with a known-good one right after the updates.

Note - even when disabled, if you do a manual update run, it will quite often happily undo everything you did to prevent it from updating all on its own in the first place. Only real way around that is to set up all your known Internet connections (wired and wifi) as "Metered." (Well, so far it seems to work...)

I meant turn off updating the video drivers, not general updates - I haven't had to undo an unhelpful change for ages, and my nVidia drivers were way out of date until the new version of Iray forced me to get new ones.
