Boosting IRAY renders speed in DAZ Studio

So I thought to share couple of tricks that helped me alot to achieve higher rendering speed with IRAY in DAZ
Though most of the experienced Artists must be well aware about those quickies already.
It may help newbies or artists who are having old NVIDA GPUs or not so high end PC (like me)

Here are some of those tips -

1. Iray Uber shader 
For IRAY to work fast and best, every object must be converted to IRay Uber shader. if an object/model doesnt have IRay presets, then convert its shader to Default IRAY Uber shader without replacing its images of course!

2. Smaller Texture size- This is just my personal experience for clothing & other 3D objects, keep your texture tiling to minimum, especially when texture images are of low res.

3. On the Render Settings - Optimizations Menu - Set the Instant Optimization  from 'memory' to 'speed'

4. if you are rendering a Close up shot and you want to highlight Models instead of background. Its better to enable DOF on main camera. I found it increases Iray speed to 2x times.

5. Make sure to render couple of draft images on smaller scales or low res initially before rendering final image

6. On Rendering Settings > Advance Tab > Enable OptiX Prime Acceleration . 

7. Connect Monitor to your PC's motherboard on board /integrated graphics port. This way you totally free up card's memory to store more objects & textures

Do share your experience. Happy Rendering! Enjoy!
