Bought new GPU, got black screen renders

Its the first time that I bought a GPU. I installed the GPU correctly, installed the drivers, installed a suitable power supply unit.

The GPU is an Nvidia GTX 1650 card. I can render characters and primitives just fine with IRAY, but not any environment.

The environments turn out black renders. No idea what to do.

The following is the error code from the log file. Hopefully this will turn up some solutions. Thanks for your help.

    It appears to be running out of memory.

    The 1650 only has 4GB of VRAM. That is serious liability with Daz and Iray. The VRAM of a GPU is the ultimate capacity of your scene. Everything in your scene needs to fit into VRAM of that GPU or the GPU will not run at all. A few years ago 4GB might have been ok, but today with all the textures and geometry in a scene, 4GB will not get far at all. I hate to say that, but is doubtful you will be able to render characters and an environment at the same time with that card. A fair number of environments can run past 4GB by themselves.

    All you can do here is to optimize as much as you can to get under that 4GB limit. Get rid of things you don't need or cannot see.

    If it is not too late, perhaps you can return the 1650. It is tough right now, the market is crazy. But if you can get a GPU with 6 or 8GB you would be better off, more so if it is 8. The 1070 is an older card, so maybe you can find one at a decent price used. Maybe, like I said the market is crazy. But the 1070 is special because it should be one of the cheapest options that offer 8GB. It is probably faster than the 1650, too. If the market was normal, these cards would be pretty cheap on ebay now, but sadly things are what they are.

    A 1060 with 6GB would be another option. This one of the most popular GPUs ever released, so there are lots of them out there.

    I cant return this card anymore. I am stuck with this one for now. I know how the supply of GPU's is these days. Its no big deal. I am only starting out with daz, I have a lot to learn. If these are the limits then so be it.

    I will see if scene optimizer can be of any use to me.

    Also, thanks for letting me know that the 4gb cards are too small for most stuff these days. I will take that into account for the future.
