Hello, Masmore I haven't used Iray for a long while but if I remember correctly and looking at your settings sample iterations 25,000 and max seconds. Of 5000 I believe what may be happening is you are timing out before you reach the 25,000 iterations due to your max seconds. To answer the second part of your question is more subjective it depends on the results you're after if your goal is that the image has too much grain I would increase the iterations but I have never needed more than 500 to,5000 or so but if its photorealism you're after its more about proper lighting and shaders and materials, I hope this has helped some.
Best regards. Kevin L

There is a denoising function (I don't remember the exact name), which will take care of many artifacts you may see.
You would normally enable it a few frames before the end of the render. You can see if that gives you improvements without doing so many iterations.
Also, there is a reduced rate of return, because every time after an update it will take more cycles to get to the next update.
For animations, the only realistic number would be less than 500 and use denoising.
You can also render at a smaller size and use something like Topaz Gigapixel Ai to enlarge the image. Sometimes that will give you more details/sharpness than you would get with just rendering at the larger format.

Wow Kevin L, thanks a lot for answers, tips work awesome, just to adjust time and iteration samples on Iray Render.
That give more realistic look that i trying to achieve.
Tyvm Animagic for the tips, thats definitely the goal make a full animation with iRay Render, that a least dont take a week to render lol. The Gigapixel AI is a great idea thanks again for help.
I never try De-Noise before is this option?
I tested the result look awesome.
