long render times?

I am fairely new to Daz 3D. the problem I am having is rendering with Iray takes well over an hour for a decent well lighted photo. even more if I want a proper background. I have been using a simple back drop for my renders because it takes so long otherwise. I have an i7 CPU and a nvidia 750 ti GPU . my GPU is newer but the rest of my PC is 6 years old.

 

is there any settings or easy lighting/scenes I can use to reduce render time? or is there something with nvidia I can do to help it along? Thanks in advance!

    The bottleneck is your hardware...The nvidia 750Ti is pretty old and slow with 640 cuda core and with only 2GB of Vram easily your scene switch on cpu render. You can try to reduce texture with scene optimizer, etc etc...but I don't know how much it will help. Did you tried to render the "benchmark" scenes present on post https://www.daz3d.com/forums/discussion/53771/iray-starter-scene-post-your-benchmarks/p1  to compare performance and have a better view of the situation?

    What Marco mentioned is right, I wouldn't expect miracles from a 750Ti. You could try https://www.daz3d.com/scene-optimizer , it can make textures smaller and optimize your scene by removing unwanted materials amongst others. Maybe it will help a little bit keeping memory free and everything under 2gb limit of your card.

    As to tips, outdoor scenes are a lot faster than indoor, so you could perhaps try one of the HDRI DOF series to render characters or objects without any additional geometry. Indoor scenes incorporate a lot more calculations on the whole, so they are slower.

    Is it still possible to render in 3delight? its been so long since I tried and I wasn't good at it then. but I have no clue how to do it anymore without mixing Iray materials as well

    Yes, 3DL is still pretty common. Many items from the store have both Iray and 3DL materials included. For ones that are Iray only, you can generally replace the shaders. There is also the RSSY Iray to 3DL converter that can do some of that, leaving you with the task of refining the shaders for certain objects.

    You might want to check out the aweSurface for 3DL which makes it possible to use true pathtracing inside DS;) An update is in the pipeline, with an Iray to awe converter.
