[SOLVED] 4.12 + RTX 2017: GPU rendering not working?

I installed 4.12 on my Windows 10 hoping to get that sweet sweet faster GPU rendering, but my renders seem to be just as slow as before. I have an RTX 2070 graphics card, and my Nvidia driver version is 432.00. Is there a step I'm missing? What else can I do to troubleshoot? Renders seem identical to the speed they previously were. Thank you!

    I think you might need to update the driver.

    430.86 should work, so  432.00 should be fne - assuming ti supports your card, I have a 1660 Super in this card and the oldest driver the nVidia site will give me is ne of the 440.x (annoyingly).

    Did you bench the card in DS 4.10 and again in 4.12 or is this just a feeling? What sorts of scenes are you rendering and how long is it taking?

    I'm not sure what "bench the card" means, but from context it sounds like you mean measuring the time it takes to render and comparing between 4.11 and 4.12. No, I did not do that. I realize that having this data would be helpful. Right now, it's just a hunch on my part - the render doesn't seem any faster based on eyeballing it. I've spent enough time doing test renders of the scene that I think I have a general sense of how long it took before I upgraded to 4.12. It takes 5 minutes to get to 10% completion right now, which is in line with what I remember in the past. There's no easy way to downgrade back to 4.11 and do this test, unfortunately.

    I'm rendering the attached scene out at 2400x2400.

    Update: I tried rendering out some other scenes and can confirm that everything is, indeed, rendering faster now and seems to be using the GPU. I also used the NVIDIA control panel to confirm that the GPU is being used. Not sure why the one scene still feels as slow to render as before, but I do see an improvement overall so I'm happy. Thanks to everyone who took the time to reply!

    there was only a relatively minor speed increase between 4.11 and 4.12. RTX was enabled in the steop from 4.10 to 4.11.
