Hi. Without any information about light setup and material set up it can only be a guess, but chances are that your curtain material is one of the reasons. Try hiding the curtains and see what happens.

Is bitmap paging (https://forum.corona-renderer.com/index.php/topic,1662.msg12232.html#msg12232) disabled?

Hello

The bitmap paging is disabled.
The problem is actually the material i changed it and rays came up to 1,5kk.
I attached some  info of  scene.
alllight are corona with some ies, and sun light is HDR in enviroment slot.

The material also attached the file.
the one i made it´s does not  really do  the same "ambient."

now i´m getting something like this 1 minute= 1 pass :)
Thanks a lot guys

Hi, this is the curtain material, right? Maybe disabling bump would be enough to make it render faster?

Have you seen this guide:

Yes, that's the surtain material.
Turning off bump did not make any diference.
The fallof setting messes corona. Specially in oppacity.

As a side note:
Your noise comes from GI, you have simple geo and neither DoF nor MoBlur.
If you are on default settings you are oversampling, thus passes take longer and are less effective at clearing noise.

Double or triple the GI/AA Multiplier and for faster renders you can lower the Msi to 4
Your rays /s should even higher.

Sorry but how many of rays your CPU shows in benchmark scene?  https://forum.corona-renderer.com/index.php/topic,559.0.html
Cause I see you get low rays in all of your scenes
Samples of images that you shared in forum attached

Well
Looks like your rays are normal for your CPU
My CPU in coronabench shows 6.5 mln.rays but in a complex scene it will only 3-3.5 mln.
And you CPU is 3 mln in test and it may be 1.2-1.8 mln. in a complex scene
All is ok
Just try to optimize your scenes like it described in the HelpDESK. Simple materials, portals, black diffuse in metal and glass itc.
Cheers!

Always want something more. More speed, more Ghz, more money (;
